"Squiggles" is a Cocoa application that shows how you can perform custom drawing and event-handling in a subclass of NSView. The sample illustrates: * Use of NSView's -drawRect: to implement custom drawing. * Use of NSView's -mouseDown: and -mouseDragged: to handle user events. * Use of NSBezierPath to draw lines.
