DWM/Transparent Button?

[Biatu]

Is there a way to have a button transparent like this in the windows start menu?

I don't think that the button is transparent rather filled with a gradient color or texture. Same with the background.

 

You can try something like this here:

expandcollapse popup

#include <ButtonConstants.au3>
#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>


_GDIPlus_Startup()
Global Const $hGUI = GUICreate("Colored Buttons using GDI+", 600, 300)
Local $y, $iHeight = 1
For $y = 0 To 300 Step $iHeight
    GUICtrlCreateLabel("", 0, $y, 600, $iHeight)
    GUICtrlSetBkColor(-1, 0xF0F060 + Int(Abs(Cos($y / 0x50) * 0x80)))
    GUICtrlSetState(-1, $GUI_DISABLE)
Next
Global Const $iBtn1 = GUICtrlCreateButton("Default", 125, 75, 150, 150)
GUICtrlSetFont(-1, 14.5, 400, 0, "Arial", 4)
Global Const $iBtn2 = GUICtrlCreateButton("", 325, 75, 150, 150, $BS_BITMAP)
Global Const $hBmp = _GDIPlus_BtnCtrlSetBgColorGradient($iBtn2, "Colored", 146, 146)
GUISetState()

Do
    Switch GUIGetMsg()
        Case $iBtn1
            MsgBox(0, "Test", "Default button has been pressed")
        Case $iBtn2
            MsgBox(0, "Test", "Colored button has been pressed")
        Case $GUI_EVENT_CLOSE
            _WinAPI_DeleteObject($hBmp)
            _GDIPlus_Shutdown()
            GUIDelete()
            Exit
    EndSwitch
Until False

I wrote a UDF for handling aero stuff before. Check them out https://www.autoitscript.com/forum/topic/75429-real-vista-aero-glass-four-functions/?page=1

[Biatu]

Thanks UEZ, and James.

UEZ, as for non-transparency, i did a test and it is surely transparent.

Results:

And James, I had already looked through your DWM funcs, and the WinAPI one already included in autoit work fine.

Thank you Team

[UEZ]

Indeed, you meant aero glass. I couldn't see that in the screenshot you have provided. Btw. this effect is already included in the _WinAPI_* stuff!

Aero glass is not working for Win8/10.

Yes, I miss aero blur in 8/10, but thankfully i still use 7. 

As for the _WinAPI_Func, is there one in partifular you couldpoint me to that would enable that kind of effect on controls? Like using different theme elements for buttons? Cause the aero theme has different styles of buttons in the msstyles file.

Thank you

[Biatu]

Any pointers?
