Howto get quality Large Icons in Toolbar using imagelist

[rogdog]

I would like to use 32x32pixel 32bit icons in a toolbar but can't get them to display correctly in Autoit (3.2.10.0)

The icons look very poor as is they are 16x16pixel 8bit icons.

The following code shows an example icon using the toolbar and imagelist. It also show the same icon using the command GUICtrlCreateIcon.

I would like the toolbar icon to look like the GUICtrlCreateIcon icon

Anyone got any ideas how I can fix this please

CODE

#include <GuiConstantsEx.au3>

#include <GuiImageList.au3>

#Include <GuiToolBar.au3>

Local $id1, $GUI, $hImage

Local Enum $idNew = 1000, $idOpen, $idSave, $idHelp

$GUI = GUICreate("(External) ImageList AddIcon", 400, 300)

GUISetState()

; Load images

$hImage = _GUIImageList_Create (32,32, 5, 3)

_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 20)

; Create toolbar

$hToolbar = _GUICtrlToolBar_Create($GUI)

_GUICtrlToolbar_SetImageList($hToolbar, $hImage)

_GUICtrlToolbar_AddButton ($hToolbar, $id1, 0)

; add Gui icon

$icon = GUICtrlCreateIcon (@SystemDir & "\shell32.dll",21, 3,50)

; Loop until user exits

Do

Until GUIGetMsg() = $GUI_EVENT_CLOSE

GUIDelete()

Replace _GUIImageList_AddIcon function in GuiImageList.au3 with the following

Func _GUIImageList_AddIcon($hWnd, $sFile, $iIndex = 0, $fLarge = False)
    Local $tIcon, $iResult, $hIcon

    $tIcon = DllStructCreate("int Handle")
    If $fLarge Then
        $iResult = _WinAPI_ExtractIconEx($sFile, $iIndex, DllStructGetPtr($tIcon), 0, 1)
    Else
        $iResult = _WinAPI_ExtractIconEx($sFile, $iIndex, 0, DllStructGetPtr($tIcon), 1)
    EndIf
    _WinAPI_Check("_GUIImageList_AddIcon", ($iResult <= 0), -1)

    $hIcon = DllStructGetData($tIcon, "Handle")
    $iResult = _GUIImageList_ReplaceIcon($hWnd, -1, $hIcon)
    _WinAPI_Check("_GUIImageList_AddIcon", ($iResult = -1), -2)
    _WinAPI_DestroyIcon($hIcon)
    Return $iResult

I'll probably add that modification to the next beta.

Thank You Gary!

I've wondered about that since using PaulIA's Auto3Lib Toolbar

and Tonedeaf's and your old GuiToolbar UDF

found a few references in google to the problem with imagelist improperly using 32 bit icons

but the code solution was beyond me.

Adding and using 32 bit alphablended images and icons to the imagelist control

Displaying Alpha (32bit) Icons with ImageLists

Thanks again
