Instance Method

disableFlushWindow

Disables the flushWindow method for the window.

Declaration

- (void)disableFlushWindow;

Discussion

If the window is buffered, disabling flushWindow prevents drawing from being automatically flushed by the NSView display... methods from the window’s backing store to the screen. This method permits several views to be drawn before the results are shown to the user.

Flushing should be disabled only temporarily, while the window’s display is being updated. Each disableFlushWindow message must be paired with a subsequent enableFlushWindow message. Invocations of these methods can be nested; flushing isn’t reenabled until the last enableFlushWindow message is sent.
