Developing ClipApp with ChatGPT
Below you’ll find the full conversation discussed in a post where a Python GUI app was developed using ChatGPT. While I tried to get ChatGPT to write most code, going in myself, fixing an issue, and providing this back to the AI typically is more efficient than trying to get 100% of the code generated by ChatGPT. As covered in the post, you’ll get the best results if you can get ChatGPT to work on small bit of code with a well-defined function.
Developing ClipApp : The full conversation with ChatGPT
You: I’m making a GUI application in python, can you pick a good library for a small program and show me code to start off with?
ChatGPT: There are several libraries you can use to create a GUI application in Python, but some of the most popular ones are Tkinter, PyQt, and wxPython.
Tkinter is a built-in library in Python for creating simple GUI applications. It is a good choice for small programs and beginners. Here is an example of creating a simple window using Tkinter:python
import tkinter as tk
root = tk.Tk()
root.mainloop()
PyQt is another popular library that is widely used for creating more advanced GUI applications. It is a set of Python bindings for the Qt library. Here is an example of creating a simple window using PyQt:python
import sys
from PyQt5.QtWidgets import QApplication, QWidget
app = QApplication(sys.argv)
window = QWidget()
window.show()
sys.exit(app.exec_())
wxPython is another popular library for creating GUI applications in Python. It is a set of Python bindings for the wxWidgets library. Here is an example of creating a simple window using wxPython:python
import wx
app = wx.App()
frame = wx.Frame(None, title='Hello World')
frame.Show()
app.MainLoop()
It’s worth noting that PyQt and wxPython are larger libraries and more complex than Tkinter. You can choose the one that best fits your needs based on your skills and the requirements of your project.
You: Let’s continue with Tkinter, I need in the middle of the screen a widget that can display an image with an editable text box underneath. Right of the text box an ‘Ok’ and ‘Cancel’ button. Left and right of the image buttons to navigate.
ChatGPT: You can accomplish this layout using a combination of Tkinter’s built-in widgets such as the Label
, Entry
, Button
, and Frame
widgets.
Here is an example of how you can create this layout:python
import tkinter as tk
from tkinter import PhotoImage
root = tk.Tk()
root.geometry("500x500")
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
#Creating Image
image = PhotoImage(file = "path_to_image")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=0, padx=50)
#Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
#Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda:print("OK button pressed"))
ok_button.grid(row=1, column=1)
#Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda:print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
#Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda:print("previous button pressed"))
previous_button.grid(row=0, column=1)
next_button = tk.Button(middle_frame, text="Next", command=lambda:print("next button pressed"))
next_button.grid(row=0, column=2)
root.mainloop()
In this example, the middle_frame
is created and added to the root window. The image_label
is created to display the image, and it’s added to the middle_frame
. The text_box
is created to allow the user to enter text, and it’s added to the middle_frame
. The ok_button
and cancel_button
are created and added to the middle_frame
.
The previous_button
and next_button
are created and added to the middle_frame
.
The grid
method is used to position the widgets within the frame.
The padx
and pady
options are used to add some padding around the widgets.
The file = "path_to_image"
should be replaced with the path of the image you want to display.
The lambda:print("OK button pressed")
and lambda:print("Cancel button pressed")
is a simple callback function to check if the button is pressed.
You can customize the layout and functionality to suit your needs.
You: I updated the code, can you add a menu bar with a button file and a dropdown with an Open button and Exit button. The exit button needs to close the app
if name == ‘main’: import tkinter as tk from tkinter import PhotoImage
root = tk.Tk()
root.geometry("1000x900")
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=1, padx=50)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
root.mainloop()
ChatGPT: You can add a menu bar in Tkinter by creating an instance of the Menu
widget and adding it to the root window. You can then create instances of the Menu
widget for each menu option and add them to the main menu. To create a dropdown menu, you can create instances of the Menu
widget and add them to the main menu using the add_cascade
method. Here is an example of how you can add a menu bar with a “File” menu that has an “Open” button and an “Exit” button:python
import tkinter as tk
from tkinter import PhotoImage
root = tk.Tk()
root.geometry("1000x900")
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=1, padx=50)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
# Creating main menu
menubar = tk.Menu(root)
root.config(menu=menubar)
# Creating File menu
file_menu = tk.Menu(menubar, tearoff=0)
menubar.add_cascade(label="File", menu=file_menu)
file_menu.add_command(label="Open", command=lambda: print("Open button pressed"))
file_menu.add_command(label="Exit", command=root.destroy)
root.mainloop()
In this example, the menubar
is created and added to the root window. The file_menu
is created and added to the main menu using the add_cascade
method. The Open
button and Exit
button are created and added to the file_menu
using the add_command
method. The command
option is used to specify the function that should be called when the button is pressed. In this case, when the Exit
button is pressed the root.destroy()
function is called which will close the app.
You can customize the menu and the functionality to suit your needs.
You: The button “Open” needs to show a dialog where a folder can be selected. Which changes do I need to make to command=lambda: print(“Open button pressed”) to do this?
ChatGPT: You can use the filedialog
module from the tkinter
library to show a dialog for selecting a folder. The askdirectory()
method is used to open a dialog for selecting a folder. Here is an example of how you can modify the “Open” button’s command to open a dialog for selecting a folder:python
import tkinter as tk
from tkinter import PhotoImage
from tkinter import filedialog
root = tk.Tk()
root.geometry("1000x900")
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=1, padx=50)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
# Creating main menu
menubar = tk.Menu(root)
root.config(menu=menubar)
# Creating File menu
file_menu = tk.Menu(menubar, tearoff=0)
menubar.add_cascade(label="File", menu=file_menu)
file_menu.add_command(label="Open", command=lambda: select_folder())
file_menu.add_command(label="Exit", command=root.destroy)
def select_folder():
folder_path = filedialog.askdirectory()
print(f"Selected folder: {folder_path}")
root.mainloop()
In this example, the function select_folder()
is defined that uses the askdirectory()
method to open a dialog for selecting a folder. The filedialog.askdirectory()
method returns the selected folder path as a string. The returned path is then printed, so that you can use it later in your code as per your requirement.
You can customize the function select_folder()
to suit your needs, for example, you can use the selected folder path to change the image displayed on the image_label
or perform other operations with the selected folder.
You: I need a function that, given a path to a folder, can give me all image file in that folder.
ChatGPT: You can use the os
module in Python to list all the files in a given folder and then filter the files to select only the image files. Here is an example of a function that takes a folder path as an argument and returns a list of all the image files in that folder:python
import os
def get_image_files(folder_path):
image_files = []
for file in os.listdir(folder_path):
if file.endswith(".jpg") or file.endswith(".jpeg") or file.endswith(".png") or file.endswith(".gif") or file.endswith(".bmp"):
image_files.append(os.path.join(folder_path, file))
return image_files
# Usage example
folder_path = "path/to/folder"
image_files = get_image_files(folder_path)
print(image_files)
In this example, the get_image_files()
function takes a folder path as an argument and uses the os.listdir(folder_path)
function to list all the files in that folder. It then iterates through the files and checks if the file has the extension of an image file (i.e .jpg, .jpeg, .png, .gif, .bmp). If the file has a valid image file extension, it’s added to the image_files
list. Finally, the image_files
list is returned.
You can adjust the image file extensions in the if
statement to match the format of images you are working with.
You can also use a library like glob
or pathlib
to get the list of files in a folder with a specific extension, which can make the code more readable.
You: My current code is shown below, I need to use the function get_image_files on the folder selected with button open and store the results somewhere. Can you refactor the code to do this.
import tkinter as tk from tkinter import PhotoImage from tkinter import filedialog import os
def get_image_files(folder_path): image_files = [] for file in os.listdir(folder_path): if file.endswith(“.jpg”) or file.endswith(“.jpeg”) or file.endswith(“.png”) or file.endswith(“.gif”) or file.endswith(“.bmp”): image_files.append(os.path.join(folder_path, file)) return image_files
def select_folder(): folder_path = filedialog.askdirectory() print(f”Selected folder: {folder_path}”)
return folder_path
if name == ‘main’: root = tk.Tk() root.geometry(“1000x900”)
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=1, padx=50)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating main menu
menubar = tk.Menu(root)
root.config(menu=menubar)
# Creating File menu
file_menu = tk.Menu(menubar, tearoff=0)
menubar.add_cascade(label="File", menu=file_menu)
file_menu.add_command(label="Open", command=lambda: select_folder())
file_menu.add_command(label="Exit", command=root.destroy)
root.mainloop()
ChatGPT: You can use the select_folder()
function to get the selected folder path and then pass that path to the get_image_files()
function to get the list of image files in that folder. One way to store the results is to create a global variable that can be accessed from anywhere in the code. You can then update this variable with the result of the get_image_files()
function. Here is an example of how you can refactor the code to do this:python
import tkinter as tk
from tkinter import PhotoImage
from tkinter import filedialog
import os
image_files = []
def get_image_files(folder_path):
image_files = []
for file in os.listdir(folder_path):
if file.endswith(".jpg") or file.endswith(".jpeg") or file.endswith(".png") or file.endswith(".gif") or file.endswith(".bmp"):
image_files.append(os.path.join(folder_path, file))
return image_files
def select_folder():
folder_path = filedialog.askdirectory()
print(f"Selected folder: {folder_path}")
global image_files
image_files = get_image_files(folder_path)
print(image_files)
if __name__ == '__main__':
root = tk.Tk()
root.geometry("1000x900")
# Creating Frame
middle_frame = tk.Frame(root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
image_label = tk.Label(middle_frame, image=image)
image_label.grid(row=0, column=1, padx=50)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating main menu
menubar = tk.Menu(root)
root.config(menu=menubar)
# Creating File menu
file_menu = tk.Menu(menubar, tearoff=0)
menubar.add_cascade(label="File", menu
You: continue
ChatGPT: continue
file_menu.add_command(label="Open", command=lambda: select_folder())
file_menu.add_command(label="Exit", command=root.destroy)scss
root.mainloop()
In this refactored code, I’ve created a global variable image_files
that is initially an empty list. The select_folder()
function is modified to call the get_image_files()
function with the selected folder path and store the result in the global image_files
variable. Also, I’ve added a print statement to print the list of image files to check if the function is working as expected.
You can now use this image_files
list to update the images displayed on the image_label
or perform other operations with the selected folder’s images.
You: can you refactor the code as a Class, ClipApp, to avoid the use of global variables and allow the app to become more modular?
ChatGPT: Yes, you can refactor the code as a class to avoid the use of global variables and make the app more modular. Here is an example of how you can refactor the code to a class, ClipApp
:python
import tkinter as tk
from tkinter import PhotoImage
from tkinter import filedialog
import os
class ClipApp:
def __init__(self):
self.root = tk.Tk()
self.root.geometry("1000x900")
self.image_files = []
# Creating Frame
middle_frame = tk.Frame(self.root)
middle_frame.pack(pady=50)
# Creating Image
image = PhotoImage(file="./img/empty_file.png")
self.image_label = tk.Label(middle_frame, image=image)
self.image_label.grid(row=0, column=1, padx=50)
# Creating navigate button
previous_button = tk.Button(middle_frame, text="Previous", command=lambda: print("previous button pressed"))
previous_button.grid(row=0, column=0)
next_button = tk.Button(middle_frame, text="Next", command=lambda: print("next button pressed"))
next_button.grid(row=0, column=2)
# Creating Text Box
text_box = tk.Entry(middle_frame)
text_box.grid(row=1, column=0, padx=50)
# Creating Ok button
ok_button = tk.Button(middle_frame, text="OK", command=lambda: print("OK button pressed"))
ok_button.grid(row=1, column=1)
# Creating Cancel button
cancel_button = tk.Button(middle_frame, text="Cancel", command=lambda: print("Cancel button pressed"))
cancel_button.grid(row=1, column=2)
# Creating main menu
menubar = tk.Menu(self.root)
self.root.config(menu=menubar)
# Creating File menu
file_menu = tk.Menu(menubar, tearoff=0)
menubar
You: continue
ChatGPT: continue
menubar.add_cascade(label="File", menu=file_menu)
file_menu.add_command(label="Open", command=self.select_folder)
file_menu.add_command(label="Exit", command=self.root.destroy)scss
def select_folder(self):
folder_path = filedialog.askdirectory()
print(f"Selected folder: {folder_path}")
self.image_files = self.get_image_files(folder_path)
print(self.image_files)
def get_image_files(self, folder_path):
image_files = []
for file in os.listdir(folder_path):
if file.endswith(".jpg") or file.endswith(".jpeg") or file.endswith(".png") or file.endswith(".gif") or file.endswith(".bmp"):
image_files.append(os.path.join(folder_path, file))
return image_files
if name == 'main':
app = ClipApp()
app.root.mainloop()vbnet
In this refactored code, I’ve created a class ClipApp
that contains all the code for the application. The __init__
method initializes the Tkinter root, sets the default geometry and creates the GUI layout, including the image label, text box, buttons, and menu bar. The select_folder()
method is now a method of the ClipApp
class and it no longer uses global variables. Instead, it updates the image_files
attribute of the ClipApp
instance. The get_image_files()
method is also now a method of the ClipApp
class and it takes the folder path as an argument.
This way, by creating an instance of the ClipApp class you can use the same code in different parts of your program, it also allows for a more organized and readable code.
You: Here is the code with your changes and a few tweaks. Can you suggest further improvements to make it more modular?

self.image_files = get_image_files(folder_path)
print(self.image_files)
if __name__ == '__main__':
app = ClipApp()
app.root.mainloop()
ChatGPT: Here are a few suggestions for further improvements to make the code more modular:You can extract the GUI layout code into its own method, such as create_layout()
, to make the __init__
method less cluttered and easier to read.You can create methods to handle the behavior of the buttons, such as previous_button_handler()
, next_button_handler()
, ok_button_handler()
, and cancel_button_handler()
, instead of using lambda functions in the button creation. This way you can more easily modify the behavior of the buttons in the future.You can create a method to handle the navigation of the images, such as navigate_images(direction)
, and call this method from the button handlers. This way you can easily add new navigation functionality without modifying the button handlers.You can move the functionality of the ‘Open’ button to a separate class that manage the images, this way you can further improve the modularity of the code.
Overall, by breaking down the code into smaller, more specific methods and classes, you can make the code more modular and easier to understand and maintain.

print("previous button pressed")
def next_button_handler(self):
next_image = self.image_handler.navigate_images("next")
self.update_image(next_image)
print("next button pressed")
def ok_button_handler(self):
print("OK button pressed")
def cancel_button_handler(self):
print("Cancel button pressed")
def update_image(self, image_path):
# code to update the image in the GUI

if __name__ == '__main__':
app = ClipApp()
app.root.mainloop()
In the update_image method you can add the code to update the image to the one passed as a parameter. In this way, you can use the same method to update the image when navigating between images and when changing the folder.
This way you can keep the code more readable, and if you need to change the way the images are handled you can simply modify the ImagesHandler class without affecting the rest of the code.
You: Lets work on the function update image, this should load the new file into the element we created with “image = PhotoImage(file=”./img/empty_file.png”)” only show the lines of code that need to change
ChatGPT: Here is the updated update_image
function that loads a new image file into the image_label
tkinter Label widget:python
def update_image(self, image_path):
new_image = PhotoImage(file=image_path)
self.image_label.configure(image=new_image)
self.image_label.image = new_image
In this example, the update_image
function takes a file path as an argument and creates a new PhotoImage
object with that file. Then it updates the image
attribute of the image_label
widget with the new image, and assign the new_image to the same attribute of the label so that the image object is not garbage collected.
You will also want to add a default image to show when no folder is selected.
You: Next we’ll need a function that can take an image path and change the extension to .txt.
ChatGPT: Here is a function that takes an image path as an argument and returns the same path but with a .txt extension:python
def image_to_text_path(image_path):
path, ext = os.path.splitext(image_path)
return path + ".txt"
You can use this function to generate the text file path that corresponds to an image file by passing the image file path to it.
You can also use os.path.splitext(file) method, which returns a tuple containing the root and extension of the file path.
In this case, the path contains the root and the ext contains the extension.
So you can then join the path and the extension with .txt
python
def image_to_text_path(image_path):
root, ext = os.path.splitext(image_path)
return root + ".txt"
This will give you the same result of the first one.
You: Take the first function and add type annotation and a docstring
ChatGPT: Here is the updated function with type annotations and a docstring:python
def image_to_text_path(image_path: str) -> str:
"""
Given an image path, return the corresponding text file path by replacing the extension with '.txt'
:param image_path: The file path of the image
:return: The file path of the text file with the same name
"""
path, ext = os.path.splitext(image_path)
return path + ".txt"
The type annotations indicate that the function takes a single argument, image_path
which is a string, and it returns a string.
The docstring gives a brief explanation of what the function does, the inputs and the expected output.
It is a good practice to add docstring and type annotations to your functions, it will help you and other developers to understand the code better and avoid errors.
You: Now let’s make a TextHandler class that can open a textfile (or create an empty one if it doesn’t exist and open that), read and store the original text and allow a new text to be written to the file.
ChatGPT: Here is an example of how the TextHandler class could be implemented:python
class TextHandler:
def __init__(self, text_path):
self.text_path = text_path
self.original_text = ""
self.load_text()
def load_text(self):
if os.path.exists(self.text_path):
with open(self.text_path, "r") as f:
self.original_text = f.read()
else:
with open(self.text_path, "w") as f:
pass
def save_text(self, new_text):
with open(self.text_path, "w") as f:
f.write(new_text)
The __init__
method initializes the class with a text file path and calls the load_text
method to load the text from the file. If the file doesn’t exist, it will create an empty one.
The load_text
method, read the text from the file and store the original text in the class variable original_text
.
The save_text
method, takes the new text as an argument and writes it to the text file.
You can use this class to read and write text to a file, and store the original text in a class variable so you can easily access it later if you need to compare it with the new text or make any other operations. You can also add some error handling to the class, to handle cases where the file is not accessible or an error occurred while reading or writing the text.
You: Add type annotation and docstrings to the previous code
ChatGPT: Here is the updated class with type annotations and docstrings:python
class TextHandler:
def __init__(self, text_path:str):
"""
Initialize a TextHandler instance with a text file path
:param text_path: the path to the text file
"""
self.text_path = text_path
self.original_text: str = ""
self.load_text()
def load_text(self) -> None:
"""
Load the text from the file, if the file doesn't exist, it will create an empty one.
"""
if os.path.exists(self.text_path):
with open(self.text_path, "r") as f:
self.original_text = f.read()
else:
with open(self.text_path, "w") as f:
pass
def save_text(self, new_text:str) -> None:
"""
Save a new text to the file
:param new_text: the text to be written to the file
"""
with open(self.text_path, "w") as f:
f.write(new_text)
The type annotations indicate the type of each variable and function arguments, it helps to make the code more readable and catch potential errors early. The docstrings give a brief explanation of what each function does, the inputs and the expected output, it helps you and other developers to understand the code better. It’s a good practice to add docstrings and type annotations to your code, it will make it easier to understand, maintain and scale.
You: Add a TextHandler to ClipApp and when updating an image use image_to_text_path to open the corresponding text file and show the text in the text box. The ok button should save the text box to the file and cancel set the text back to the original.

from image_handler import ImageHandler
from text_handler import TextHandler
def test_image_handler():
# Create test image file
with open("test_image.jpg", "wb") as f:
f.write(b"test image")
# Create ImageHandler instance
image_handler = ImageHandler("test_image.jpg")
# Test that image_path is set correctly
assert image_handler.image_path == "test_image.jpg"
# Test that image_data is set correctly
assert image_handler.image_data == b"test image"
# Test that image is saved correctly
image_handler.save_image("test_image_copy.jpg")
with open("test_image_copy.jpg", "rb") as f:
assert f.read() == b"test image"
# Clean up test files
os.remove("test_image.jpg")
os.remove("test_image_copy.jpg")
def test_text_handler():
# Create test text file

You can run these test by running pytest
command in your terminal on the file where the test are defined.
You will also need to import the classes ImageHandler and TextHandler in your test file.
You: This app is intended for annotating folders with images for training a generative AI (like stable diffusion). Can you provide a readme (readme.md) in markdown format covering installation, intended use,…
ChatGPT: Image Annotation App
This app is intended for annotating folders with images for training a generative AI like stable diffusion. It allows you to navigate through the images in a folder, view them, edit and save the captions for each image.InstallationClone the repository or download the zip filebash
git clone https://github.com/yourusername/image-annotation-app.git
```Install the required packages```pip install -r requirements.txt
```Run the app```python app.py
```Usage
When the app starts, a dialog will appear to select the folder containing the images to be annotated.
Once the folder is selected, the images will be displayed one by one.
Use the "Previous" and "Next" buttons to navigate through the images.
Use the text box below the image to add or edit the caption for the image.
Use the "OK" button to save the changes and "Cancel" to discard any changes.
From the "File" menu, select "Open" to change the folder containing the images.
Select "Exit" to close the app.NotesThe App only considers the images with the following extensions: .jpg, .jpeg, .png, .gif, .bmpThe App creates a txt file with the same name of the image, in the same folder where the image is, and saves the caption on it.ContributionIf you want to contribute to this project, please open a pull request.Feel free to open an issue if you find a bug or have a feature request.License

**You**: Will this code work with the nuitka package to create a stand alone executable? Or pyinstaller?
**ChatGPT**: The code should work with both ```nuitka``` and ```pyinstaller``` to create a stand-alone executable.
```Nuitka``` is a Python compiler that converts the Python code into an executable binary. You can use it to create an executable from your Python script, and it will bundle the required libraries and dependencies into the binary, so the end-user doesn't need to have Python installed on their machine.
```Pyinstaller``` is another similar package, which also converts Python code into an executable binary. It also bundles the required libraries and dependencies into the binary.
Both ```nuitka``` and ```pyinstaller``` are popular choices for creating executables from Python code, and they have been known to work well with Tkinter, the GUI library used in this project.
However, it's always a good idea to test the executable on a machine that doesn't have Python installed, to ensure that the executable is working correctly and that all of the required dependencies are included.
**You**: How to use nuitka here?
**ChatGPT**: To use Nuitka to create an executable from your Python script, you can use the following steps:Install Nuitka using pip:```pip install nuitka
```Go to the directory where your script is located in the command lineRun the following command to create the executablecss
```css
nuitka --standalone --python-version=3.x script.py
Where script.py
is the name of your script and 3.x
is the version of python you are using.
Nuitka will generate a build directory with the executable and all the required dependencies.
Test the executable on a machine that doesn’t have Python installed to ensure that it is working correctly.
Note: When creating the executable with nuitka, you may need to specify certain dependencies that are not automatically bundled. This can be done by specifying the --include-modules
option in the command line and providing a comma-separated list of modules. This can be useful if you are using any additional modules, like the os module in this case, that are not automatically bundled by Nuitka.
For example, you can use the following command:css
nuitka --standalone --python-version=3.x --include-modules=os script.py
And that should create the executable for your script.
You: The image needs to be a fixed size of 512x512 pixels. If it is to big it needs to be scaled down which changes need to made to ClipApp to do this?
ChatGPT: To scale down the image to a fixed size of 512x512 pixels, you can use the PIL
library (Python Imaging Library). You can install it using pip:```pip install pillow
Here are the changes that you need to make to the ClipApp class to scale down the image:Import the ```PIL.Image``` module at the top of the file:python
```python
from PIL import Image
```In the ```select_folder``` function where you get the images, before displaying it, open the image with PIL, and resize it to 512x512 pixels.python
```python
def select_folder(self):
folder_path = filedialog.askdirectory()
print(f"Selected folder: {folder_path}")
self.image_files = get_image_files(folder_path)
print(self.image_files)
current_image = self.image_files[0]
img = Image.open(current_image)
img = img.resize((512, 512), Image.ANTIALIAS)
self.image_label.configure(image=img)
self.image_label.image = img
```Where you update the image, scale down the image before displaying itpython
```python
def update_image(self, new_image_path):
img = Image.open(new_image_path)
img = img.resize((512, 512), Image.ANTIALIAS)
self.image_label.configure(image=img)
self.image_label.image = img
This should scale down the image to a fixed size of 512x512 pixels before displaying it. The resize
method of the Image
class takes two arguments: the new size (in this case, 512x512) and the resampling filter to use. The Image.ANTIALIAS
filter is a high-quality downsampling filter that minimizes aliasing artifacts.
You can also use other resampling filter like Image.NEAREST
,Image.BICUBIC
or Image.LANCZOS
depending on the quality you want to achieve.
You: Is there a way to do this built in tkinter without using PIL?
ChatGPT: Yes, it’s possible to resize an image without using the PIL library by using the PhotoImage
class from tkinter. The PhotoImage
class has a zoom
method that can be used to resize an image.
Here is an example of how you can use the zoom
method to resize an image to a fixed size of 512x512 pixels:python
def select_folder(self):
folder_path = filedialog.askdirectory()
print(f"Selected folder: {folder_path}")
self.image_files = get_image_files(folder_path)
print(self.image_files)
current_image = self.image_files[0]
img = PhotoImage(file=current_image)
img = img.zoom(512/img.width(), 512/img.height())
self.image_label.configure(image=img)
self.image_label.image = img
And for the update_image
functionpython
def update_image(self, new_image_path):
img = PhotoImage(file=new_image_path)
img = img.zoom(512/img.width(), 512/img.height())
self.image_label.configure(image=img)
self.image_label.image = img
You will need to divide the size you want to scale to by the current width and height of the image. This will give you the zoom factor that you can pass to the zoom method.
Note that this method can be less efficient than using PIL because the image will be loaded into memory multiple times. Also, PIL offers more options for resizing and adjusting the image quality.
Please note that the zoom
method from PhotoImage
class does not support the resampling filter like PIL
does, so the image quality could be affected.
You: Next i would like the left and right arrow keys do the same as the previous and next button
ChatGPT: To make the left and right arrow keys control the “Previous” and “Next” buttons, you can use the bind
method of the root window to bind the arrow keys to the corresponding button commands. Here is an example of how you can do this:python
def __init__(self):
self.root = tk.Tk()
self.root.geometry("1000x900")
self.image_files = []
self.root.bind("<Left>", self.previous_image)
self.root.bind("<Right>", self.next_image)
# ...
def previous_image(self, event):
current_index = self.image_files.index(self.current_image)
if current_index == 0:
new_index = len(self.image_files) - 1
else:
new_index = current_index - 1
self.update_image(self.image_files[new_index])
def next_image(self, event):
current_index = self.image_files.index(self.current_image)
if current_index == len(self.image_files) - 1:
new_index = 0
else:
new_index = current_index + 1
self.update_image(self.image_files[new_index])
In this example, the previous_image
function is bound to the left arrow key, and the next_image
function is bound to the right arrow key. The event
argument is passed to the function, but it is not used in this example.
You will also need to add an attribute current_image
to keep track of the current displayed image.python
def update_image(self, new_image_path):
self.current_image = new_image_path
img = PhotoImage(file=new_image_path)
img = img.zoom(512/img.width(), 512/img.height())
self.image_label.configure(image=img)
self.image_label.image = img
You may also want to change the previous_button
and next_button
commands to call the previous_image
and next_image
functions respectively, so that both the buttons and the arrow keys perform the same action.
You: Is this using the Imagehandler correctly?
ChatGPT: The ImageHandler class is not being used in the code provided. In order to use it correctly, you would need to create an instance of the ImageHandler class in the ClipApp constructor and use it to manipulate the image. Here is an example of how you can do this:python
def __init__(self):
self.root = tk.Tk()
self.root.geometry("1000x900")
self.image_files = []
self.image_handler = ImageHandler()
self.root.bind("<Left>", self.previous_image)
self.root.bind("<Right>", self.next_image)
# ...
def update_image(self, new_image_path):
self.current_image = new_image_path
img = self.image_handler.resize_image(new_image_path, 512, 512)
self.image_label.configure(image=img)
self.image_label.image = img
In this example, we create an instance of the ImageHandler class and use it to resize the image when calling the update_image
function.
You could also add a method open_image
to the ImageHandler class, so that it can be used to open an image and resize it.python
class ImageHandler:
def __init__(self):
pass
def open_image(self, path:str, width:int, height:int):
img = PhotoImage(file=path)
img = img.zoom(width/img.width(), height/img.height())
return img
And then you can update the code of update_image
to use this methodpython
def update_image(self, new_image_path):
self.current_image = new_image_path
img = self.image_handler.open_image(new_image_path, 512, 512)
self.image_label.configure(image=img)
self.image_label.image = img
However, it’s important to note that, since the PhotoImage class does not allow to resize image, you will need to use a library such as PIL(Python Imaging Library) to resize the image, or use another library.
You: Will this app show a command line window along the GUI? Can this be prevented so only the GUI is shown when running the app once compiled with nuitka
ChatGPT: When you compile the app with Nuitka, it will create a standalone executable that runs the Python script without the need for a Python interpreter. When the executable runs, it may or may not show a command-line window depending on the platform and how the executable was built.
To prevent a command-line window from showing when running the app, you can use the --standalone
option when compiling with Nuitka. This option will package the Python interpreter and all dependencies into the executable, making it a self-contained executable.
Also, you can use the --windows-disable-console
option to prevent a console window from opening in Windows.
You can use the following command to build the standalone executable :css
nuitka --standalone --windows-disable-console main.py
Here main.py is the main file of the project.
It’s also important to note that if you’re using any external libraries that are not built-in in python, you will need to make sure that these libraries are available to the executable. You can use the --include-plugin-directory
option to include the location of the library in the executable.
Please also be aware that this method may not work on all platforms, and some other steps may be required to prevent the command line window from showing when running the app.
You: I like to improve the layout. Can an element span multiple columns in a grid?
ChatGPT: Yes, you can make an element span multiple columns in a grid using the columnspan
option when creating the element.
For example, you can use the following code to create a label that spans three columns:python
label = tk.Label(root, text="This label spans 3 columns")
label.grid(row=0, column=0, columnspan=3)
Here, the label is created on the first row and first column and it spans 3 columns.
You can also use the rowspan
option to make an element span multiple rows in a grid.
For example, you can use the following code to create a button that spans two rows:python
button = tk.Button(root, text="This button spans 2 rows")
button.grid(row=0, column=0, rowspan=2)
Here, the button is created on the first row and first column and it spans 2 rows.
You can combine both rowspan
and columnspan
options to create an element that spans multiple rows and columns.python
label = tk.Label(root, text="This label spans 2 rows and 3 columns")
label.grid(row=0, column=0, rowspan=2, columnspan=3)
Here, the label is created on the first row and first column and it spans 2 rows and 3 columns.
You can use the above options to improve the layout of your GUI.
It’s important to note that when an element spans multiple rows or columns, other elements in the grid should not be placed in the rows or columns that are spanned by the element.

ChatGPT: The error is caused by the fact that the zoom method expects integers as arguments, however, width / new_image.width() and height / new_image.height() will return floats. To fix this, you can use the int() function to convert the result to integers before passing them to the zoom method.less
new_image = new_image.zoom(int(width / new_image.width()), int(height / new_image.height()))
Alternatively, you can use the round() function to round the result to the nearest integer before passing it to the zoom method.less
new_image = new_image.zoom(round(width / new_image.width()), round(height / new_image.height()))
This way, the image can be scaled down to the fixed size of 512x512 pixels.
You: when creating a textbox, with the code below, I’d like it to be 100% of the possible width. Can you change the code below to do so?
self.text_box = tk.Entry(middle_frame)
self.text_box.grid(row=1, column=1, columnspan=6)
ChatGPT: Sure, you can set the columnspan
option to 6
to make the text box span across 6 columns.python
self.text_box = tk.Entry(middle_frame)
self.text_box.grid(row=1, column=0, columnspan=6, padx=50, pady=50, sticky="ew")
You can also set the sticky
option to “ew” to make the text box expand to fill the available space horizontally( east and west )
Also added padx and pady to keep it in center and make it look good.
You: the text_box element is only one line. Is it possible to increase the height and enable word wrap so it can show the text on multiple lines?
ChatGPT: Yes, you can use a Text widget instead of an Entry widget, which allows you to specify the height and width of the text box and enables word wrap.lua
self.text_box = tk.Text(middle_frame, wrap=tk.WORD)
self.text_box.config(height=10, width=50)
self.text_box.grid(row=1, column=1, columnspan=6)
This will create a Text widget that is 10 lines high and 50 characters wide, with word wrap enabled. The columnspan
attribute in the grid
method allows the widget to span across multiple columns.
You: can the width of the text box be set to fill the full available width ?
ChatGPT: Yes, you can set the width of the text box to fill the full available width by using the sticky
option in the grid
method and setting it to tk.W+tk.E
, which will make the widget expand to fill the available space in the horizontal direction.
Here is an example:python
self.text_box = tk.Entry(middle_frame)
self.text_box.grid(row=1, column=1, columnspan=6, sticky=tk.W+tk.E)
You could also use pack
method with fill
option set to tk.X
python
self.text_box = tk.Entry(middle_frame)
self.text_box.pack(fill=tk.X)
You: Can you update the function below to work with a Text instead of an Entry?
def update_image(self, image_path: str, width: int = 512, height: int = 512):
"""

:param image_path: the path of the image file to be displayed
:param width: Width of the image to be displayed. default is 512 pixels
:param height: Height of the image to be displayed. default is 512 pixels
"""
new_image = PhotoImage(file=image_path)
# new_image = new_image.zoom(width / new_image.width(), height / new_image.height())
self.image_label.configure(image=new_image)
self.image_label.image = new_image
text_path = image_to_text_path(image_path)
self.text_handler = TextHandler(text_path)
self.text_box.delete(0, tk.END)
self.text_box.insert(0, self.text_handler.original_text)
ChatGPT: Sure, here is an updated version of the function that uses a Text
widget instead of an Entry
widget:python
def update_image(self, image_path: str, width: int = 512, height: int = 512):
"""
Update the image displayed in the app with a new image
:param image_path: the path of the image file to be displayed
:param width: Width of the image to be displayed. default is 512 pixels
:param height: Height of the image to be displayed. default is 512 pixels
"""
new_image = PhotoImage(file=image_path)
# new_image = new_image.zoom(width / new_image.width(), height / new_image.height())
self.image_label.configure(image=new_image)
self.image_label.image = new_image
text_path = image_to_text_path(image_path)
self.text_handler = TextHandler(text_path)
self.text_box.delete(1.0, tk.END) # change from delete(0, tk.END)
self.text_box.insert(tk.END, self.text_handler.original_text) # change from insert(0, self.text_handler.original_text)
In this version, we are using the Text
widget’s delete
method to delete the contents of the text box, which takes two indices to specify the start and end of the text to delete, with the indices being in the format of line.column
. We also use the insert
method to insert the text, which takes an index and the text to insert.
You: Update the function below to work with a Text widget instead of an Entry
def save_text(self):
"""
Save the text in the text box to the corresponding text file
"""
new_text = self.text_box.get()
self.text_handler.save_text(new_text)
ChatGPT: def save_text(self): “”” Save the text in the text box to the corresponding text file “”” new_text = self.text_box.get(“1.0”, “end-1c”) self.text_handler.save_text(new_text)
#Note: “1.0” indicates the first character of the first line and “end-1c” indicates the last character of the last line in the Text widget. The “-1c” is used to exclude the newline character at the end of the text. This is to ensure that the text saved matches the text displayed in the Text widget.
You: could this also use tk.END as the previous example?
ChatGPT: Yes, you can use tk.END when working with a Text widget instead of an Entry. The method is the same, but instead of using the get()
method on the text box, you would use the get(1.0, tk.END)
method, which gets all the text in the widget starting from the first character (1.0) to the end (tk.END). Here is an example of how the modified save_text
function would look like:python
def save_text(self):
"""
Save the text in the text box to the corresponding text file
"""
new_text = self.text_box.get(1.0, tk.END)
self.text_handler.save_text(new_text)
You: I have a line below to link a function to pressing ‘Enter’, change it to trigger the function when ‘Ctrl’+’Enter’ are pressed
ChatGPT: python
self.text_box.bind("<Return>", self.save_text)
change it to:python
self.text_box.bind("<Control-Return>", self.save_text)
You: When a Text element is in focus and the user presses Enter a newline is added to the text. Is it possible to ignore this?
ChatGPT: Yes, it is possible to ignore the newline that is added when the user presses Enter in a Text widget. One way to do this is to use the bind()
method to bind a function to the <Return>
event that prevents the default behavior of inserting a newline. The function can then perform any desired action, such as calling another function or updating a variable.
Here is an example of how to bind a function to the <Return>
event in a Text widget:less
def on_return(event):
# code to be executed when the user presses 'Ctrl'+'Enter'
# ...
text_widget = tk.Text()
text_widget.bind("<Control-Return>", on_return)
Note that, the event argument will contain the event information and the function can be programmed as per the requirement.
You: a newline is still added to the text-box, where is the issue with the code?
ChatGPT: The issue with the code is that the bind()
method is still bound to the <Return>
event, which is the default event for the newline action. In order to avoid this behavior, you need to unbind the <Return>
event from the Text widget.
You can use the unbind()
method of the Text widget to unbind the <Return>
event like this: self.text_box.unbind("<Return>")
.
Another solution is to change the binding to a key that isn’t already bound to something else, such as the <Control-Return>
event.
You can bind the function to the <Control-Return>
event like this: self.text_box.bind("<Control-Return>", self.save_text)
You: that doesn’t work either
ChatGPT: The problem is likely that the Return
key event is still being bound to the default behavior of inserting a newline. One solution would be to unbind the Return
key event before binding the custom key event.python
self.text_box.bind("<Return>", lambda event: event.widget.event_generate("&#8203;`oaicite:{"index":0,"invalid_reason":"Malformed citation <<CustomReturn>>"}`&#8203;"))
self.text_box.bind("&#8203;`oaicite:{"index":1,"invalid_reason":"Malformed citation <<CustomReturn>>"}`&#8203;", self.save_text)
This way the default behavior of the Return
key is unbound and it will only trigger the new binded key event.
You can also use event.widget.unbind("<Return>")
before binding your custom event.
You: I’m currently using the code below, and newlines are still added? can you fix it?
self.text_box.unbind("<Return>")
self.text_box.bind("<Return>", lambda _: print("Enter ignored"))
ChatGPT: The problem is that the bind
method is only binding to the Return
key event and not the Enter
key event.
The Return
key event is usually generated by the enter key on the numeric keypad, and the Enter
key event is usually generated by the enter key on the main keyboard.
So, you can try to fix it by binding to the Enter
key event by replacing Return
with Enter
:python
self.text_box.unbind("<Enter>")
self.text_box.bind("<Enter>", lambda _: print("Enter ignored"))
orpython
self.text_box.unbind("<Return>")
self.text_box.bind("<KP_Enter>", lambda _: print("Enter ignored"))
It’s also worth noting that in your case, you might need to use the Text
widget tag_config
method to change the default behavior of the Enter
key event. But you need to be more specific about the behavior of your text widget and the desired outcome.
You: For testing ImagesHandler and TextHandler with pytest, where do I put the code and how to I run the tests
ChatGPT: To test the ImagesHandler
and TextHandler
classes using pytest, you will need to create a separate directory for your tests and place test files in that directory. It is a common practice to name this directory tests
and to place it in the same directory as your module (the module containing the classes you want to test).
You can then create a test file for each class you want to test, such as test_imageshandler.py
and test_texthandler.py
. In each of these files, you will import the class you are testing and write test functions that will test the different methods of the class. These functions should be named test_*
, so that pytest can discover them automatically.
To run the tests, you can navigate to the root directory of your project in the terminal and run the command pytest
. This will run all the test files that pytest can discover in the current directory and its subdirectories.
Alternatively, you can run pytest path/to/tests
to run the tests in a specific directory, or pytest path/to/test_file.py
to run the tests in a specific file.
Also, you might want to install pytest in your enviroment as it may not be installed by default. You can do this by running pip install pytest
You: My package is in a folder clipapp, draw a file structure where the tests should be for pytest to find them
ChatGPT: clipapp/ clipapp/ init.py image_handler.py text_handler.py tests/ init.py test_image_handler.py test_text_handler.py
You can put the test files in the tests folder, and make sure the folder contains an init.py file to make it a package. Then in the command line navigate to the parent folder of clipapp and run pytest or pytest clipapp to run the tests.

class. The test functions include test_get_image_files
, test_navigate_images
and test_current_image
.

function creates an instance of the ImagesHandler
class and calls the get_image_files
method passing a directory path ‘tests/test_images’ as the argument. The function then asserts that the length of the returned image_files
list is 2 and that all the files in the list have valid image file extensions.
The test_navigate_images
function creates an instance of the ImagesHandler
class and calls the get_image_files
method passing a directory path ‘tests/test_images’ as the argument. It then sets the current_image_index
to 0 and calls the navigate_images
method with the direction as ‘next’ and ‘previous’ and asserts that the returned image file path is the expected one.
The test_current_image
function creates an instance of the ImagesHandler
class and calls the get_image_files
method passing a directory path ‘tests/test_images’ as the argument. It then sets the current_image_index
to 0 and 1 and asserts that the returned current_image path is the expected one.

assert text_handler.original_text == "new text"
In the above example, I’ve used tmpdir
fixture from pytest to create temporary files. This allows to create test files without polluting the file system and also cleaning them up automatically after the test.
In the test_init
function, we test that the instance is correctly initialized with the text_path and the original_text is empty string.
In the test_load_text
function, we create a temporary text file, write some text to it, create a TextHandler instance and load the text. Then we assert that the original_text attribute is the same as the text written to the file.
In the test_save_text
function, we create a temporary text file, create a TextHandler instance, save a new text to the file and assert that the text in the file is the same as the new text and the original_text attribute is also the same as the new text.
