Control transparency of elements on a GUI Topic is solved

[poisonborz]

Hey, is there a way to add transparent elements to a GUI in a way that their transparency is controllable?

Is GDIP the only way? My theory is, that if this can't be done with AHK only, there would be a separate GDIP layer needed that would move with the AHK window... but this seems to be really cumbersome for a very simple thing. Is there a better way?

You can use WinSet, Transparent

Code: Select all

Gui, Add, Picture, HWNDhPic, % A_AhkPath
Gui, Add, Slider, w300 Range0-255 ToolTip vTransVal gChangeTransparency, 255
Gui, Show
Return

ChangeTransparency:
	GuiControlGet, TransVal
	WinSet, Transparent, %TransVal%, ahk_id %hPic%
Return

GuiClose:
ExitApp

Ooooh thanks, I always thought WinSet commands can only just affect the whole window

FYI, this use of WinSet requires Win 8+.
