How to set a GUICtrl Click through?

Recommended Posts


Hi everyone, I want to set a guicrl click through (not a GUI) like this:


   Red area: can click through

   Blue area: can not click through

Because I create a GUI and set ExStyle $WS_EX_TOPMOST, I can't click on taskbar icon when it is in front of the taskbar. I want to set an ctrl such as label ctrl click through and others ctrl is still non-click through.

Use $WS_EX_TRANSPARENT combined with $WS_EX_LAYERED ex-style on a GUI you want to click through (only for display).

Then use _WinAPI_SetLayeredWindowAttributes to set the transparent color.

Br, FireFox.
