[issue37693] IDLE/Tkinter: File names are hidden in "Open" menu (Linux)

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

This is definitely not an IDLE issue. To open files, IDLE calls tkinter.filedialog.Open(parent, filetypes).show(initial_dir, initial_file).  Open is a subclass of filedialog._Dialog(commondialog.Dialog).  It sets command = "tk_getOpenFile".  Dialog.show calls the command with root.tk.call after fixing passed in options.  It then fixes the result and returns it.  I believe this command calls the native file dialog.  Since tkinter's option processing, converting python object to strings suitable for tk.call, is OS independent, I presume the problem is in tk_getOpenFile.  I suspect tcl/tk developers have trouble keeping up with the parade linuxes and window managers.  (What is a 'DE?)

If so, this should be closed as 3rd party.  If you want to test first, bypass IDLE and most of tkinter with the following, run directly in Python.

>>> import tkinter as tk
>>> r = tk.Tk()
>>> r.tk.call("tk_getOpenFile")  # select codecontext.py, hit 'Open'
'C:/Programs/Python38/Lib/idlelib/codecontext.py'
>>> r.tk.call("tk_getOpenFile")  # hit 'Cancel'
''
