Would you tell me how to know a window finishes resizing?
NSView has a bunch of accessors to deal with this, because you sometimes need to customize the way a view redraws to make it not take too much time during a live resize. If you need to get this info somewhere else (like in your controller) you could subclass one of the views in the window to override the notification methods, and have it call your controller in response.
—Jens /* Live resize support */// a view receives viewWillStartLiveResize before the frame is first changed for a live resize
- (void)viewWillStartLiveResize;// a view receives viewWillEndLiveResize after the frame is last changed for a live resize
- (void)viewDidEndLiveResize;// inLiveResize can be called from drawRect: to decide between cheap and full drawing
- (BOOL)inLiveResize; #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_4/* A view that returns YES for -preservesContentDuringLiveResize is responsible for invalidating its own dirty rects during live resize */
- (BOOL)preservesContentDuringLiveResize;/* -rectPreservedDuringLiveResize indicates the rect the view previously occupied, in the current coordinate system of the view */
- (NSRect)rectPreservedDuringLiveResize;/* On return from -getRectsExposedDuringLiveResize, exposedRects indicates the parts of the view that are newly exposed (at most 4 rects). *count indicates how many rects are in the exposedRects list */ - (void)getRectsExposedDuringLiveResize:(NSRect[4])exposedRects count: (NSInteger *)count;
