Button with images

[Holger]

Cause often there are question how to use images on buttons I post my old scrap here.

From XP on Buttons do support Image_Lists.

More information you can find here:

http://windowssdk.msdn.microsoft.com/en-us...y/ms673340.aspx

In the following example I just use small icons (16x16) for the imagelist.

You can also use large icons or bmp-images (and maybe other formats) in these lists...

More infos here:

Here is now the scrap/beginning/code sample :

expandcollapse popup

#include <GUIConstants.au3>

Global Const $ILC_MASK                      = 0x0001
Global Const $ILC_COLOR32                   = 0x0020

Global Const $BCM_FIRST                     = 0x1600
Global Const $BCM_SETIMAGELIST              = $BCM_FIRST + 0x0002

Global Const $BUTTON_IMAGELIST_ALIGN_LEFT   = 0
Global Const $BUTTON_IMAGELIST_ALIGN_RIGHT  = 1
Global Const $BUTTON_IMAGELIST_ALIGN_TOP    = 2
Global Const $BUTTON_IMAGELIST_ALIGN_BOTTOM = 3
Global Const $BUTTON_IMAGELIST_ALIGN_CENTER = 4 ; Doesn't draw text


$hGUI   = GUICreate("Colored button")

$btn1   = GUICtrlCreateButton("Button1", 10, 10, 90, 25)
Button_AddIcon($btn1, "shell32.dll", 6, $BUTTON_IMAGELIST_ALIGN_LEFT)

$btn2   = GUICtrlCreateButton("Button2", 10, 50, 90, 25)
Button_AddIcon($btn2, "shell32.dll", 21, $BUTTON_IMAGELIST_ALIGN_RIGHT)

$btn3   = GUICtrlCreateButton("Button3", 10, 90, 50, 50)
Button_AddIcon($btn3, "shell32.dll", 32, $BUTTON_IMAGELIST_ALIGN_TOP)

$btn4   = GUICtrlCreateButton("Button4", 10, 140, 50, 50)
