[Sorry if this article is a repeat - but it never seemed to show
up on our newsfeed, and nobody's replied anyhow. Perhaps we've
got NNTP problems? I don't know.]
From View.rtf:
acceptColor:atPoint:
- acceptColor:(NXColor)color atPoint:(NXPoint *)aPoint
Allows a View to accept a color. If your subclass of View
implements this method, it will be invoked when the user
drags a color (as from an NXColorWell) into your View.
So, I implement -acceptColor:atPoint:. All it does yet is
printf( "Here I am!\n"). But, when I pop up a color panel, and
drag a color into the View, nothing happens. No printf, and later,
when I add code to do something else, like change the View's color,
that doesn't happen, either.
So, what's up? Am I just not doing something right? There's not
much area to go wrong, here, and I've checked the spelling against
the documentation about a billion times. It just doesn't seem to
work. Anyone out there got an example of receiving colors for your
View?
Later,
