arm64-tkinterdnd2-for-trixie

A patched/fixed version of tkinterdnd2 that actually works on Raspberry Pi 5 (arm64) running Debian Trixie.

The official pip install tkinterdnd2 fails on this platform due to tkdnd library compatibility issues (wrong ELF class, version mismatches, etc.).
This repo provides a working replacement.

Tested on

• Raspberry Pi 5 (8 GB)
• Raspberry Pi OS 64-bit (Debian Trixie / Bookworm successor)
• Python 3.11–3.13 (venv)

What was fixed / changed

• Downgraded to libtkdnd2.9.2.so (compiled correctly for arm64)
  • Original 2.9.3 failed with ELF class mismatch
  • 2.9.5 also didn't work
• Modified tkdnd/linux-arm64/pkgIndex.tcl → changed all 2.9.3 references to 2.9.2

That's it — no other code changes.

It ain't perfect

• in order to get this to work as it doesn't out of the box, I had to bypass the core drop signal as it kept erroring over e.serial = getint(nsign), _tkinter.TclError: expected integer but got "%#"
• so if you're having issues, check to see that the test script test_tk_dnd.py works and if it does then you have a place to start.

How to use it (recommended: method 2)

Method 1: Overwrite files in existing pip install (quick but dirty)

1. pip install tkinterdnd2 in your venv
2. Copy these files from this repo:
   • modified_tkinterdnd2/tkdnd/linux-arm64/libtkdnd2.9.2.so
   • modified_tkinterdnd2/tkdnd/linux-arm64/pkgIndex.tcl → overwrite (must match version)
3. Use normal import: from tkinterdnd2 import TkinterDnD, DND_ALL, ...

Method 2: Use the whole folder as a local module (cleaner, recommended)

1. Copy the entire modified_tkinterdnd2/ folder into your project's module directory. Or create a modules directory and put it in your sys.path:

   import sys
   sys.path.insert(0, os.path.expanduser("~/your/modules/path"))

2. In your script, :

   from modified_tkinterdnd2 import TkinterDnD, DND_ALL

Happy Dragging and Dropping..
