Getting _GDIPlus_GraphicsDrawImage to register a press

[Champak]

I have a function that spawns the following gui. I want to be able to click on the graphics created to activate a different function but I don't know how. I made $hGraphics and  $hGraphics a global variable (I didn't know which to use to accomplish this) at the top of my script and put it as a case in the main loop, but that just constantly calls it without actually clicking on the pic. I tried various ways in notify and command, but it doesn't seem to be picked up. How can I accomplish this?

 

$GuiProductImage = GUICreate($sName, $sImageDimension, $sImageDimension, $sLeft, $sTop, $sPopUp, Default, $sParent)
    GUISetBkColor ( 0xffffff, $GuiProductImage )
    GUISetState(@SW_SHOWNOACTIVATE)

    $hGraphics = _GDIPlus_GraphicsCreateFromHWND($GuiProductImage)
    $hGraphic2 = _GDIPlus_GraphicsDrawImage($hGraphics, $hBitmap_Scaled, $adjustedX, $adjustedY)
    

    _GDIPlus_GraphicsDispose($hGraphics)
    _GDIPlus_BitmapDispose($hBitmap)
    _GDIPlus_BitmapDispose($hBitmap_Scaled)
    _GDIPlus_Shutdown()
;   GUIDelete($GuiProductImage)

Note: I found a different solution, but now I'm just curious of getting the image to register a press.

Click on what picture? It's just a draw over the GUI. You can check if a click was pressed inside the GUI or use a picture control and check if it was clicked. Something like this:

; Probably you already have the $hBitmap_Scaled already

$GuiProductImage = GUICreate($sName, $sImageDimension, $sImageDimension, $sLeft, $sTop, $sPopUp, Default, $sParent)
$cPic = GUICtrlCreatePic('', 0, 0, $sImageDimension, $sImageDimension)
GUISetBkColor(0xffffff, $GuiProductImage)
$hHBITMAP = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hBitmap_Scaled)
_WinAPI_DeleteObject(GUICtrlSendMsg($cPic, 0x0172, 0, $hHBITMAP))
_WinAPI_DeleteObject($hHBITMAP)
GUISetState(@SW_SHOWNOACTIVATE)

While True
    Switch GUIGetMsg()
        Case -3
            ExitLoop
        Case $cPic
            MsgBox(0, '', 'Clicked')
    EndSwitch
WEnd
