DesktopBuffer:Int32

Returns: A buffer handle.

Description

Gives the buffer of the desktop. Drawing to it does nothing here, and reading from it gives nothing.

Differences

• Drawing on, or reading from, the desktop does not work: it is a buffer of one black pixel that starts over every time this is called, so the screen of the computer is never touched and nothing shows behind the windows. The original draws on the Windows desktop with the DirectDraw driver only.

Examples

win = CreateWindow("In front", 40, 20, 240, 120, Desktop(), 3)
; Safe to call, but nothing is painted on the desktop.
