Adding a new type of NSButton

Subject: Adding a new type of NSButton
From: P Teeson <email@hidden>

Environment is Mac OS X 10.4.11 Xcode 2.5

I need a new type of NSButton/NSButtonCell that I am calling an NSLatchButton. Once it is pushed it stays pushed - pushing it again does not revert it back to unpushed state. (Of course there would be a method to set it to it's unlatched state but pushing the button would not invoke that action)

However I'm not sure how to approach this. Should I use categories, extensions, or subclass or what?

If I were dealing with the source code I would add to the button types enums and add a method or case to deal with that type.

But what suggestions do you have?

TIA for your elegant wisdom.....

respect....

Peter
