Icon on top of icon

Recommended Posts


Is it possible to put one icon on top of another? Here's my code:

$PowerIco = GUICtrlCreateIcon("shell32.dll", -28, 85, 130)

$DeleteIco = GUICtrlCreateIcon("shell32.dll", -132, 85, 130)

For those who are asking questions, look in the help file first. I'm tired of people asking stupid questions about how to do things when 10 seconds in the help file could solve their problem.[quote name='JRowe' date='24 January 2010 - 05:58 PM' timestamp='1264381100' post='766337'][quote name='beerman' date='24 January 2010 - 03:28 PM' timestamp='1264372082' post='766300']They already have a punishment system for abuse.[/quote]... and his his name is Valik.[/quote]www.minikori.com

Hi, you can set 2 images to 1 Icon control with a bit of trickery.

Here's a crude example that doesn't have any error checking for incorrect user input..

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

$hGui = GUICreate('', 200, 200, -1, -1)
$DeleteIco = GUICtrlCreateIcon("", 0, 10, 10, 32, 32)
GUICtrlSetTip(-1, "Click icon to delete.")
GUISetState(@SW_SHOW, $hGui)

$hIcon1 = _SetTwoIconsToOneIconControl($hGui, $DeleteIco, "shell32.dll", 27, 131)

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            If $hIcon1 Then _WinAPI_DestroyIcon($hIcon1)
        Case $DeleteIco
            $hIcon1 = 0

Func _SetTwoIconsToOneIconControl($hWnd, $cID, $sFile, $iName1, $iName2)
    Local Const $STM_SETIMAGE = 0x0172
    Local $hCID, $tL1, $pL1, $tL2, $pL2, $hImage1, $hGraphic, $hImage2, $hIcon, $hSetIcon
    $hCID = GUICtrlGetHandle($cID)
    $tL1 = DllStructCreate("int Handle[1]")
    $pL1 = DllStructGetPtr($tL1)
    $tL2 = DllStructCreate("int Handle[1]")
    $pL2 = DllStructGetPtr($tL2)    
    _WinAPI_ExtractIconEx($sFile, $iName1, $pL1, 0, 1)
    _WinAPI_ExtractIconEx($sFile, $iName2, $pL2, 0, 1)
    $hImage1 = DllCall($ghGDIPDll,"int", "GdipCreateBitmapFromHICON", "hWnd", DllStructGetData($tL1, "Handle", 1), "int*", 0)
    $hGraphic = _GDIPlus_ImageGetGraphicsContext($hImage1[2])
    $hImage2 = DllCall($ghGDIPDll,"int", "GdipCreateBitmapFromHICON", "hWnd", DllStructGetData($tL2, "Handle", 1), "int*", 0)
    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage2[2], 0, 0, _GDIPlus_ImageGetWidth($hImage1[2]), _GDIPlus_ImageGetHeight($hImage1[2]))
    $hIcon = DllCall($ghGDIPDll,"int", "GdipCreateHICONFromBitmap", "hWnd", $hImage1[2], "int*", 0)
    $hSetIcon = DllCall("user32.dll", "hwnd", "SendMessage", "hwnd", $hCID, "int", $STM_SETIMAGE, "int", $IMAGE_ICON, "int", $hIcon[2])
    _WinAPI_DestroyIcon(DllStructGetData($tL1, "Handle", 1))
    _WinAPI_DestroyIcon(DllStructGetData($tL2, "Handle", 1))
    If $hSetIcon[0] <> 0 Then _WinAPI_DeleteObject($hSetIcon[0])
    Return $hIcon[2]

Any Questions ?


Edit: Changed the way the hIcon is destroyed.

Very nice example smashly!

One question: can it be used to set an image for a Listbox item? I opened a thread with this question, and martin has pointed to this topic so i will see how to draw icon image on the control, but the problem is that list item have no(?) control id, how we can get the handle of each item (index) and apply this method to set the icon?


Sorry for the offtopic.

I posted a question back in your thread MrCreator.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
