The 'doublebuffered' property

Boolean scalar

Valid for: All visible controls and windows

The doublebuffered property is a boolean scalar which, under Windows, determines whether drawing takes place to an off-screen bitmap before the window is updated. The default is false (0). Setting doublebuffered to true (1) takes more memory, but may reduce screen flicker especially if you are moving shapes on screen.

Under MacOS and Linux, this property has no effect, since the operating system determines whether an off-screen bitmap is used for drawing. Double-buffered drawing is always used under MacOS X and later.
