fs28 Together with the NSColorPickingDefault protocol, NSColorPickingCustom provides a way to add color pickers'd0custom user interfaces for color selection'd0to an application's NSColorPanel. The NSColorPickingDefault protocol provides basic behavior for a color picker. The NSColorPicker class adopts the NSColorPickingDefault protocol. The easiest way to implement a color picker is to create a subclass of NSColorPicker and use it as a base upon which to add the NSColorPickingCustom protocol.

fs28 Getting the View

fs28 fi-6552 {f3 -} (NSView *)b provideNewView:b0 (BOOL)i firstRequesti0 tab Returns the view containing the color picker'27s user interface. This message is sent to the color picker whenever the color panel attempts to display it; the argument indicates whether this is the first time the message has been sent. If i firstRequesti0 is YES, the method should perform any initialization required (such as lazily loading a nib file).
