The 'ImageID' can be easily obtained by using UseImage() or ImageID() from the Image library. It can be an image loaded with LoadImage() or created in memory with CreateImage(). To have a real transparent background, the 'icon' (.ico) file format is recommanded.
The later checking of an event, means if the user clicked on an item of the toolbar, will done the same way like checking for a menu event with the command EventMenuID().
Example:
If OpenWindow(0, 0, 0, 150, 25, #PB_Window_SystemMenu |#PB_Window_ScreenCentered, "ToolBar")
CreateImage(0,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB(255,255,255))
Box(4,4,8,8,RGB(255,0,0))
StopDrawing()
CreateImage(1,16,16)
StartDrawing(ImageOutput())
Box(0,0,16,16,RGB(255,0,0))
Box(4,4,8,8,RGB(255,255,255))
StopDrawing()
If CreateToolBar(0, WindowID())
ToolBarImageButton(0,UseImage(0))
ToolBarImageButton(1,UseImage(1))
EndIf
Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf
