Help with beginner layered windows

10 posts in this topic

I'm very new to things such as layered windows, and I need some help. I understand that a layered window's clickability depends on its transparency, but how, exactly, do you change its transparency? Also, why does this code fail to display a button that seems to be floating in midair?

#include <WindowsConstants.au3>
$handle = GUICreate("", 800, 800, 1, 1, $WS_POPUP)
GUISetState(@SW_SHOW)
$handle2 = GUICtrlCreateButton("Click me.", 200, 200, 100, 100)
While 1
WEnd

I know that this would probably be obvious to anyone who knows anything about layered windows, but... I AM a noob.

benzrf,

This is how to use a layered window to get a transparent GUI: :)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <WINAPI.au3>

$hGUI = GUICreate("Test", 500, 500, -1, -1, $WS_POPUP, $WS_EX_LAYERED)
GUISetBkColor(0xABCDEF) ; Set GUI back colour

$hButton = GUICtrlCreateButton("Click me to exit", 10, 50, 100, 100)

_WinAPI_SetLayeredWindowAttributes($hGUI, 0xABCDEF, 250) ; Make that colour virtually transparent

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton
            Exit
    EndSwitch
WEnd

All clear? Please ask if not. ;)

Uhhh... When I tried running your code, it said that the function _WinAPI_SetLayeredWindowAttributes was undefined...

Uhhh... When I tried running your code, it said that the function _WinAPI_SetLayeredWindowAttributes was undefined...

Then we must guess that your version of AutoIt is almost 2 (!!) years old. I recommend you update to latest version of both AutoIt and SciTE4AutoIt3. It's free after all so what's stopping you? ;)

Either that, or you didn't copy all of Melba's code, as the function is defined in WinAPI.au3 which is clearly included.

And it claims that it's undefined...

So you're seriously saying that a script like this:

#include <WinAPI.au3>

$sToCall = "_WinAPI_SetLayeredWindowAttributes"
Call($sToCall, 0, 0)
$iErr = @error
$iExt = @extended

MsgBox(0, @AutoItVersion, Hex($iErr, 4) & Hex($iExt, 4))

Returns both 3.3.6.1 and says DEADBEEF? ;)
