The window can not be clicked through (tkinter wm_attributes("-transparentcolor", color) method)

[astqx]

Description of the issue

When using the tkinter module's method wm_attributes("-transparentcolor", color), the specified color will be treated as transparent (the region of the window containing the color can be clicked through). If the script is run normally / packaged using the --onedir mode of pyinstaller, the behaviour is as expected but, if --onefile mode is used, click-through does not work in the resulting exe.

Context information (for bug reports)

• Output of pyinstaller --version: 4.1
• Version of Python: 3.8
• Platform: Windows

A minimal example program which shows the error

from tkinter import *

def focus(event):
	print(event)

root=Tk()
root.config(bg='blue')
root.wm_attributes('-transparentcolor',root['bg'])
root.attributes('-topmost',True)

root.bind('<FocusIn>',focus)
root.bind('<FocusOut>',focus)

root.mainloop()

Can you try with PyInstaller 4.2?

Click-through indeed does not seem to be working in onefile with 4.1, but it seems to work with 4.2. According to git bisect, 3c3228d was the commit that fixed it.

I don't exactly see how linked commit fixed this, but the click-though does work with 4.2. Thank you and sorry to have wasted your time.

That is very weird. Does adding an icon break it again by any chance?

[astqx]

Just tested, adding an icon does not break it, using --icon=NONE does, click-through did not work.

Hmm, that is indeed the case, and a very useful hint.

And as is often the case around here, the problem was lying somewhere else, but was triggered by icon being disabled. Or, prior to 3c3228d, by not being specified.
