I have a custom window (NSBorderlessWindowMask) that requires using the standard close/minimize/zoom buttons.
NSWindow's standardWindowButton:forStyleMask: method works great for creating these buttons and adding to my custom (frame) view. However, the mouse over effect does not work without using undocumented methods. Mainly, overriding _mouseInGroup: in the button's superview (frame view) and returning YES when the mouse is over the buttons. This works, and I notice Google Chrome uses the same method, but I really dislike using undocumented APIs like this, especially for UI work. The other problem with using these widgets is their placement within my custom frame view requires custom positioning. I suppose I could get their position from an existing window (asking for their frame in their private superview) but that is also undocumented, although less guesswork. The alternative is to use the Carbon HITheme API, which to my surprise works under 64-bit. The HIThemeDrawTitleBarWidget() and HIThemeGetWindowRegionHit() are the main functions, and they do the work of properly positioning the widgets. However, their Y position is still dependent on this imaginary content view so their position still has to be fudged, unless I can assume their height == the height of the title bar? I guess I can still play with that a little. However, they do require you to track the mouse down state, which isn't too much extra work, but the Cocoa widgets get this for free as buttons. I suppose my question is, what is the best way to do this to support future versions of Mac OS X? Is there better support coming for using the Cocoa buttons, and is this undocumented API expected to change? Is the HITheme here to stay for 10.7 and beyond for all architectures and can it do everything I need?
