// calling -[className] on the content views of NSWindow, NSTabItem, and NSBox all return NSView, so I'm assuming I just need to override these
|
|
// fornunately:
|
|
// - NSWindow resizing calls -[setFrameSize:] (but not -[setFrame:])
|
|
// - NSTabView resizing calls both -[setFrame:] and -[setFrameSIze:] on the current tab
|
|
// - NSTabView switching tabs calls both -[setFrame:] and -[setFrameSize:] on the new tab
|
|
// so we just override setFrameSize:
