tkinterdnd2 0.6.0

TkinterDnD2 is a python wrapper for George Petasis'' tkDnD Tk extension version 2

TkinterDnD2

Eliav2/tkinterdnd2 is a fork of the (unmaintained) pmgagne/tkinterdnd2 which is a python wrapper for tkdnd .

This repo was originally forked and edited for the purpose of publishing to pypi so one could simply install this package with pip install tkinterdnd2.

This repository is being maintained to ensure availability of tkinterdnd2 into the future, providing Tkinter native drag and drop support for windows, unix and Mac OSX.

What is TkDnD

tkDnD2 is a tcl/Tk extension adding native drag and drop support.

This repository contains the compiled binaries from https://github.com/petasis/tkdnd/releases/tag/tkdnd-release-test-v2.9.5 and my own compiled binaries for full Tcl 9 support: https://github.com/Squiblydoo/tkdnd.

Install

python -m pip install tkinterdnd2

Usage

import tkinter as tk

from tkinterdnd2 import DND_FILES, TkinterDnD

root = TkinterDnD.Tk()  # notice - use this instead of tk.Tk()

lb = tk.Listbox(root)
lb.insert(1, "drag files to here")

# register the listbox as a drop target
lb.drop_target_register(DND_FILES)
lb.dnd_bind('<<Drop>>', lambda e: lb.insert(tk.END, e.data))

lb.pack()
root.mainloop()

see any of the demos for usage examples.

Framework Integration

If you are using a GUI framework that manages its own Tk root window (such as PySimpleGUI or CustomTkinter), you cannot use TkinterDnD.Tk() as the root. Instead, call TkinterDnD.require() on the framework's existing root after it has been created. This loads tkdnd into the shared Tcl interpreter, making drag-and-drop available to all widgets in the process.

The following are some simple examples:

PySimpleGUI

import PySimpleGUI as sg
from tkinterdnd2 import TkinterDnD, DND_FILES

def on_drop(event):
    window["-FILE-"].update(event.data)

layout = [
    [sg.Text("Drag & Drop a File Here")],
    [sg.Input("", key="-FILE-")],
    [sg.Button("OK"), sg.Button("Cancel")],
]

window = sg.Window("File Drop", layout, finalize=True)

# Inject DnD into PySimpleGUI's own root — no dummy window needed
TkinterDnD.require(window.TKroot)

# Register any widget as a drop target
window["-FILE-"].widget.drop_target_register(DND_FILES)
window["-FILE-"].widget.dnd_bind("<<Drop>>", on_drop)

while True:
    event, values = window.read()
    if event in (sg.WIN_CLOSED, "Cancel"):
        break

window.close()

CustomTkinter

import customtkinter as ctk
from tkinterdnd2 import TkinterDnD, DND_FILES

def on_drop(event):
    entry.delete(0, "end")
    entry.insert(0, event.data)

app = ctk.CTk()
app.title("File Drop")

# Inject DnD into CustomTkinter's root
TkinterDnD.require(app)

entry = ctk.CTkEntry(app, width=400, placeholder_text="Drag a file here...")
entry.pack(padx=20, pady=20)

entry.drop_target_register(DND_FILES)
entry.dnd_bind("<<Drop>>", on_drop)

app.mainloop()

pyinstaller

When using pyinstaller, you should use the hook-tkinterdnd2.py file included to collect the TkDnD binaries and build them into the project. To use it, copy it into the base directory of your project, then run pyinstaller as follows:

pyinstaller -F -w myproject/myproject.py --additional-hooks-dir=.
