On WSL2: Cannot clickthrough example hud

[twilwa]

expected behavior: i should be able to click on stuff through the hud

actual behavior: clicking on things underneath the hud doesn't function. I can click-drag to highlight text displayed on the HUD, however. after a few minutes, or so, a window for "Web Inspector" appears, although it doesn't appear to be clickable, after which the HUD transparent window can be click-dragged off of the screen. there's no associated terminal output, as far as i can tell.

i suspect it may either be an issue with wsl, or an issue with my package manager, tea (tea.xyz), which sometimes messes with PATHs and such.

steps to reproduce: ./run.sh as per the readme, window key to show taskbar, left click to browser window.

environment: Ubuntu 23.04 via WSL2

Perhaps the issue is related to Windows not supporting GTK's input_shape_combine_region function, which hudkit uses to make the window click-through ("transparent" to mouse clicks);

On the Win32 platform, this functionality is not present and the function does nothing.

A possible workaround using AutoHotkey, from forum user dangerdogL2121 in 2015: It appears an AutoHotkey script can make windows click-through (archive link), using some Windows-specific window attribute. The crucial lines:

WinTitle = Calculator ;or whatever you want
SetTitleMatchMode, 2
WinSet, ExStyle, +0x20, % WinTitle ; 0x20 = WS_EX_CLICKTHROUGH

Hudkit's window title is hudkit overlay window.

If you try this, let me know! If it works, we could detect WSL and replicate that trick.
