Hello everyone,
I'm subclassing NSButton, and I'm trying to find out how to know if my
view is the "key view." Say I have 8 buttons on a screen, and you can
tab through them. I want my button subclass to be able to respond to
the fact that it is now "selected" as the keyView (by drawing itself
differently, as it's a graphical program), through the nextKeyView
chain.
I've looked through the documentation from NSButton all the way up to
NSObject, and the only thing I can seem to find is the -nextKeyView
and previousKeyView methods, but I can't seem to find something like
"-isKeyView:".
Almost like the FocusRing, but instead of drawing the focus ring, I
want to modify the button itself.
That leads me to believe I am tackling this problem the completely
wrong way.
I've read the documentation on NSResponder, all the stuff on keyboard
input, View programming, etc. There has to be something that isn't
clicking.
-[NSResponder becomeFirstResponder] & -[NSResponder
resignFirstResponder]
Also you can ask the window you are in for the first responder and
see if that is yourself.
