🧩 Parameters

🌙 Dark Mode Preview

☀️ Light Mode Preview

Package constants

This module has constants that can be used outside or inside the dialog, they are used to obtain paths like /home/user or /home/user/.config/ Here is a basic example

#!/usr/bin/env python3 
import customtkinter as ctk 
from CTkFileDialog import askopenfilename
from CTkFileDialog.Constants import HOME

root = ctk.CTk()

def open_file(): 
    f = askopenfilename(initial_dir=HOME, autocomplete=True)
    if f: 
        print(f"file selected: {f}")

ctk.CTkButton(master=root, command=open_file, text="Open File").pack(padx=10, pady=10, anchor=ctk.CENTER)

root.mainloop()

And here are the constants available from the package

Mini Dialog

This is a parameter of the file dialog, but it's more powerful than the default one. As I mentioned earlier, it doesn't support parameters like tooltip, preview_img, or video_preview.

🌙 Dark Mode Preview

☀️ Light Mode Preview

The mini design wasn't created by me; it was created by this user, and all credit goes to him. I also want to thank him for creating that design in advance.
