GUI doesn't show controls

1 post in this topic

Hi there,

I changed a few things from a piece of code on these forums. (http://www.autoitscript.com/forum/index.php?showtopic=102961)

I changed it so far to this:

#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <StaticConstants.au3>
Global Const $AC_SRC_ALPHA = 1
Global Const $Title = "Todo Corner"
Global Const $Version = "2.0"
Global Const $FullTitle = $Title & " " & $Version

_GDIPlus_Startup()

$pngSrc = @ScriptDir & "\GUIBK.png"
;This allows the png to be dragged by clicking anywhere on the main image.
GUIRegisterMsg($WM_NCHITTEST, "WM_NCHITTEST")
$GUI = _GUICreate_Alpha($FullTitle, $pngSrc)
$myGuiHandle = WinGetHandle($FullTitle)
GUISetState()

;This is an invisible control container. You can create regular windows controls on this panel.
$controlGui = GUICreate("ControlGUI", 450, 300, 0, 0, $WS_POPUP, BitOR($WS_EX_LAYERED, $WS_EX_MDICHILD), $myGuiHandle)
GUICtrlCreateButton ( "lol", 10, 10, 100, 20 )
GUICtrlSetBkColor($controlGui, 0xFF00FF)
GUICtrlSetState(-1, $GUI_DISABLE)


;This png is draggable as if it were a child window. It has about 50 pixels at the top that allow it to be dragged
$TransparentButtonTest = GUICreate("Test321", 1, 1, 1, 1, $WS_EX_MDICHILD, $WS_EX_LAYERED, $myGuiHandle)

GUISetState()

    ;Create a new bitmap, this way the original opened png is left unchanged
    $hGraphic1 = _GDIPlus_GraphicsCreateFromHWND(_WinAPI_GetDesktopWindow())
    $hBitmap = _GDIPlus_BitmapCreateFromGraphics($w, $h, $hGraphic1)
    $hGraphic2 = _GDIPlus_ImageGetGraphicsContext($hBitmap) 
    
    ; Draw the original opened png into my newly created bitmap
    _GDIPlus_GraphicsDrawImageRect($hGraphic2, $hImage, 0, 0, $w, $h)

    ;Create the font
    $hBrush = _GDIPlus_BrushCreateSolid ("0xFF" & Hex($iRGB, 6))
    $hFormat = _GDIPlus_StringFormatCreate()
    $hFamily = _GDIPlus_FontFamilyCreate ($sFont)
    $hFont = _GDIPlus_FontCreate ($hFamily, $iSize, $iStyle)
    $tLayout = _GDIPlus_RectFCreate ($iX, $iY, 0, 0)
    $aInfo = _GDIPlus_GraphicsMeasureString ($hGraphic2, $sText, $hFont, $tLayout, $hFormat)
    
    ;Draw the font onto the new bitmap
    _GDIPlus_GraphicsDrawStringEx ($hGraphic2, $sText, $hFont, $aInfo[0], $hFormat, $hBrush)
    
    ;Cleanup the no longer needed resources

    _GDIPlus_GraphicsDispose ($hGraphic2)
    _GDIPlus_GraphicsDispose ($hGraphic1)

    ;Return the new bitmap
    Return $hBitmap
EndFunc

But I can't seem to add buttons or labels.. I tried it between those 2 lines:

GUICtrlCreateButton ( "lol", 10, 10, 100, 20 )
GUICtrlSetBkColor($controlGui, 0xFF00FF)

But it just doesn't work. It doesn't even work when I try it on the original example

Could anyone please help?

Thanks in advance, Cas Cornelissen
