Working with layered window and background gif

[qsek 16]

Hi,

I tried several cominations of styles but not get it to work to remove that heavy flickering, if you resize the GUI.

Just run the code and try resizing the 2 GUI's and you see what i mean. (you have to see the desktop)

Only happens when the GUI is a Child to the Desktop. Its oviously a matter of the right Window Styles.

Who can help?

PS: You need grey.gif :

expandcollapse popup

#include <GUIConstants.au3>

Opt("GUIOnEventMode", 1)  ; Change to OnEvent mode

$hWnd = ControlGetHandle("Program Manager", "", "SysListView321")

; -------------------GUI 1 (Strange Drawing effect)--------------------

$style   = BitOR($WS_CLIPCHILDREN, $WS_SIZEBOX,$WS_THICKFRAME,$WS_DLGFRAME) ; thin toolbar, just Close Button
$exstyle = BitOR($WS_EX_LAYERED,$WS_EX_TOOLWINDOW,$WS_EX_WINDOWEDGE)

$controlGUI = GUICreate("ControlGUI", 400, 200, 100, 50, $style, $exstyle)

Opt("WinTitleMatchMode", 4)
DllCall("user32.dll", "int", "SetParent", "hwnd", $controlGui, "hwnd", WinGetHandle("classname=Progman")) ; Set Window as Destop Child

$pic = GUICtrlCreatePic(@ScriptDir & "\grey.gif",0,0,2000,2000,$SS_CENTERIMAGE)
GuiCtrlSetState(-1,$GUI_DISABLE)

$button = GUICtrlCreateButton("test1234567",10,10)

$label = GUICtrlCreateLabel("Strange Drawing effect",110,12,140,50)
GUICtrlSetBkColor(-1,$GUI_BKCOLOR_TRANSPARENT)
GUICtrlSetColor(-1,0xFFFFFF)

GUISetState()
GUISetOnEvent($GUI_EVENT_CLOSE, "ExitScript")
GUICtrlSetOnEvent($button, "msg")
; -------------------GUI 2 (Extreme Flicker)--------------------
$style   = BitOR($WS_SIZEBOX,$WS_THICKFRAME,$WS_DLGFRAME) ; $WS_CLIPCHILDREN makes the flicker
$exstyle = BitOR($WS_EX_LAYERED,$WS_EX_TOOLWINDOW,$WS_EX_WINDOWEDGE)

$controlGUI = GUICreate("ControlGUI", 400, 200, 650, 50, $style, $exstyle)

Opt("WinTitleMatchMode", 4)
DllCall("user32.dll", "int", "SetParent", "hwnd", $controlGui, "hwnd", WinGetHandle("classname=Progman")) ; Set Window as Destop Child

$pic = GUICtrlCreatePic(@ScriptDir & "\grey.gif",0,0,2000,2000,$SS_CENTERIMAGE)
GuiCtrlSetState(-1,$GUI_DISABLE)

$button = GUICtrlCreateButton("test1234567",10,10)

$label = GUICtrlCreateLabel("Extreme Flicker",110,12,140,50)
GUICtrlSetBkColor(-1,$GUI_BKCOLOR_TRANSPARENT)
GUICtrlSetColor(-1,0xFFFFFF)

GUISetState()
GUISetOnEvent($GUI_EVENT_CLOSE, "ExitScript")
GUICtrlSetOnEvent($button, "msg")

; -------------------GUI 3 (Smooth resize but not Desktopchild)--------------------

$style   = BitOR($WS_CLIPCHILDREN, $WS_SIZEBOX,$WS_THICKFRAME,$WS_DLGFRAME)
$exstyle = BitOR($WS_EX_LAYERED,$WS_EX_TOOLWINDOW,$WS_EX_WINDOWEDGE)

$controlGUI = GUICreate("ControlGUI", 400, 200, 100, 350, $style, $exstyle)

$pic = GUICtrlCreatePic(@ScriptDir & "\grey.gif",0,0,2000,2000,$SS_CENTERIMAGE)
GuiCtrlSetState(-1,$GUI_DISABLE)

$button = GUICtrlCreateButton("test1234567",10,10)

$label = GUICtrlCreateLabel("Smooth resize but not Desktopchild",110,12,140,50)
GUICtrlSetBkColor(-1,$GUI_BKCOLOR_TRANSPARENT)
GUICtrlSetColor(-1,0xFFFFFF)

GUISetState()
GUISetOnEvent($GUI_EVENT_CLOSE, "ExitScript")
