Recommended Posts

Hi

How do i get this Ellipse invisible and the Gui still black?

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

HotKeySet ( "!a", "_ende" )

_GDIPlus_Startup()


$hgui = GUICreate ( "MyGUI", @DesktopWidth, @DesktopHeight, 0, 0, $WS_POPUP, BitOR ( $WS_EX_LAYERED, $WS_EX_TOPMOST ) )
GUISetBkColor ( 0x000000 )
_WinAPI_SetLayeredWindowAttributes($hgui, 0xABCDEF, 255)
GUISetState ( @SW_SHOW )

$hwnd=_GDIPlus_GraphicsCreateFromHWND ( $hgui )

;~ $schwarz=_GDIPlus_PenCreate ( 0xFF000000, 500, 2 )
$stift=_GDIPlus_BrushCreateSolid ( 0xFFABCDEF )

;~ _GDIPlus_GraphicsDrawEllipse ( $hwnd, @DesktopWidth/2, @DesktopHeight/2-100, 50, 50, $schwarz )
_GDIPlus_GraphicsFillEllipse ( $hwnd, @DesktopWidth/2-100, @DesktopHeight/2-100, 200, 200, $stift )


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

;~ _GDIPlus_PenDispose ( $schwarz )
_GDIPlus_BrushDispose ( $stift )
_GDIPlus_GraphicsDispose ( $hwnd )
_GDIPlus_Shutdown()

Func _ende()
    Exit
EndFunc

Func _WinAPI_SetLayeredWindowAttributes($hwnd, $i_transcolor, $Transparency = 255, $dwFlages = 0x03, $isColorRef = False)
   ; progandy
    If $dwFlages = Default Or $dwFlages = "" Or $dwFlages < 0 Then $dwFlages = 0x03
    If Not $isColorRef Then
        $i_transcolor = Hex(String($i_transcolor), 6)
        $i_transcolor = Execute('0x00' & StringMid($i_transcolor, 5, 2) & StringMid($i_transcolor, 3, 2) & StringMid($i_transcolor, 1, 2))
    EndIf
    Local $Ret = DllCall("user32.dll", "int", "SetLayeredWindowAttributes", "hwnd", $hwnd, "long", $i_transcolor, "byte", $Transparency, "long", $dwFlages)
    Select
        Case @error
            Return SetError(@error, 0, 0)
        Case $Ret[0] = 0
            Return SetError(4, _WinAPI_GetLastError(), 0)
        Case Else
            Return 1
    EndSelect
EndFunc  ;==>_WinAPI_SetLayeredWindowAttributes

Just to clarify, you want the circle still there, but transparent? Or you want it gone?

change this

$stift=_GDIPlus_BrushCreateSolid ( 0xFFABCDEF )

to

$stift=_GDIPlus_BrushCreateSolid ( 0x00ABCDEF )

Still there, just transparent

Is that a serious suggestion? ^_^

Try drawing a filled rectangle in any colour you like over the whole screen. Then draw an elipse or any other shape, and also try a line, using the transparent colour to generate transparent sections.

Here's another example of the problem. I'm sure it's a matter of understanding transparent colours and GDI+ which I don't, but I've not seen a convincing excplanation yet.

That's why I was asking for clarification ;) you asked for an invisible ellipse.

I suppose that's a fair enough reason ^_^

Thats mine topic xD

Hm it seems that the Funktion _WinAPI_SetLayeredWindowAttributes don't works with GDI+

Yes.

You can do it with a graphic though

GUISetState()
_WinAPI_SetLayeredWindowAttributes($gui, 0xABCDEF, 255)
$g1 = GUICtrlCreateGraphic(0,0,500,500)
GUICtrlSetBkColor(-1,0xFFFFFF)
GUICtrlSetGraphic(-1,$GUI_GR_COLOR,0xABCDEF,0xABCDEF)
GUICtrlSetGraphic(-1, $GUI_GR_ELLIPSE, 50, 50, 200, 330, 270)
GUICtrlSetGraphic(-1, $GUI_GR_REFRESH)
sleep(7000)




Func _WinAPI_SetLayeredWindowAttributes($hwnd, $i_transcolor, $Transparency = 255, $dwFlages = 0x03, $isColorRef = False)
  ; progandy
    If $dwFlages = Default Or $dwFlages = "" Or $dwFlages < 0 Then $dwFlages = 0x03
    If Not $isColorRef Then
        $i_transcolor = Hex(String($i_transcolor), 6)
        $i_transcolor = Execute('0x00' & StringMid($i_transcolor, 5, 2) & StringMid($i_transcolor, 3, 2) & StringMid($i_transcolor, 1, 2))
    EndIf
    Local $Ret = DllCall("user32.dll", "int", "SetLayeredWindowAttributes", "hwnd", $hwnd, "long", $i_transcolor, "byte", $Transparency, "long", $dwFlages)
    Select
        Case @error

        Case $Ret[0] = 0
            Return SetError(4, _WinAPI_GetLastError(), 0)
