_WinAPI_SetWindowPos background/bottom

[Champak]

My gui is set up for one gui to fade out and another to fade in. Since there doesn't seem to be a way to fade one gui into another...haven't really searched for that but it seems like a multithread duty...I'm having the 1st gui fade to a blank gui of the same color and then the 2nd gui fade in. Problem is I have to bring in the blank gui in the background to serve as the backdrop for the fade. I found _WinAPI_SetWindowPos in the help, but I guess I'm not using it correctly, haven't really seen anything here about it that clearly defines how I should use it. So in short, I want to bring a window up ("show"), in the background.

So:

1/ Does the _WinAPI_SetWindowPos need to be called each time, or just once?

2/ Do I have the settings correct?

3/ Is there a better/different way to do what I want?

Global $HWND_BOTTOM

Case $msg = $dddd
                _WinAPI_SetWindowPos($BlankFadeGUI, $HWND_BOTTOM, -1, -1, -1, -1, BitOR($SWP_NOMOVE,$SWP_NOSIZE))
                GUISetState(@SW_SHOW,$BlankGUI);This is not to actualy be seen at this point, it should be behind GUI1 at this point
                _WinAnimate($GUI1, $AW_FADE_OUT, 400)
                _WinAnimate($GUI2, $AW_FADE_IN, 400)
                GUISetState(@SW_HIDE,$BlankGUI)

Hi, thanks, that's great. I improved it slightly to combine everything:

_FadeOutIn($hGUI_1, $hGUI_2, $hGUI_3)

Func _FadeOutIn($hWinOut, $hWinIn, $hWinTrans)

    WinSetTrans($hWinIn, "", 255)
    For $n = 0 To 255
        WinSetTrans($hWinOut, "", 255 - $n)
        WinSetTrans($hWinTrans, "", $n)
        ;Sleep(5)
    Next
    GUISetState(@SW_HIDE, $hWinTrans)
    
EndFunc   ;==>_FadeOutIn

Your version was also giving a flicker sometimes in the transition which was irritating the hell out of me. My version still gives a flicker, but just SLIGHTLY less.

Now here is the problem, within my app which has now reached 5200 lines, there is a flicker EVERY TIME (with both versions). And also the transition is taking between 3.2 and 7.5 seconds. The 7.5 seconds is only during the very first fade transition, the second one is around 5 seconds, then all others average between 3.2 and 5 seconds. Obviously this is unacceptable. Now I don't really think this has to do with the size of the app, but more to the weight of the GUIS...which are relatively large. So any other ideas of how to accomplish this.

Sleep() was introduced to slow the loop down intentionally. If no Sleep() is not fast enough for you, then Step the For/Next loop to make the transition faster:

For $n = 0 To 255 Step 5
        WinSetTrans($hWinOut, "", 255 - $n)
        WinSetTrans($hWinTrans, "", $n)
    Next
