Does anyone have any ideas on how to _visually_ indicate that an
NSImageView is not editable? Since it doesn't really do anything
different when it's editable or not editable, it's tough for the
user to tell which state is which.
I'm thinking that maybe there's a way to make the image slightly
more transparent - play with its alpha or something. Has anyone
else had to do something similar?
It's trivial to create a subclass of NSImageView that in some way
manipulates or overdraws the image it's displaying in order to
illustrate some kind of state. I did one not to long ago that used a
gradient to simulate a spotlight calling attention to one portion of
the current image, for example. But it also strikes me that in doing
so you're compromising the quality and/or content of the image from
the user's standpoint. Might it make more sense to have a small, but
clear, external indicator instead of a subtle content manipulation?
