Why would it be necessary to make a subclass? Shouldn't it be
possible to pass NSBorderlessWindowMask as the "styleMask" parameter
in -[NSWindow initWithContentRect:styleMask:backing:defer:] to get a
window with no title bar (which thus can't be dragged)?
I suppose depending upon your needs, you may be able to avoid a
subclass.
For my stuff, my subclass provides a bit more than just an override to
the designated initializer:
- Provides a mouse-moved delegate
- Overrides canBecomeKeyWindow and canBecomeMainWindow (content window
always returns YES for these APIs; blanking window always returns NO)
- Accessibility overrides - to mainly route 'confirm' and 'cancel'
actions to appropriate controls.
- Misc APIs that provide conveniences to my custom UI framework.
A category was not possible in my case since I needed to add ivars.
