Hello, List:
I've been experimenting with custom views and Quartz and all related
nose-bleed-and-migraine-inducing subjects. I think I understand the
whole drawing thing at least well enough to find my own answers in most
cases, now, but I am still at a loss regarding containers ...
Basically, I can't seem to find a comprehensive, easy-to-digest
explanation of:
- How NSScrollView and NSClipView objects work together.
- What the difference between containerView and documentView really
is.
- How to *properly* make a custom NSView subclass draggable ONLY
within the bounds of a superview (I'm using NSContainsRect([superView
bounds], rect) as a hit test).
- How to drag and drop a custom view between two different superviews
(okay, this one is probably well-explained, I just don't get it).
I HAVE THOROUGHLY RTFM, so kindly put that rather presumptuous
comment aside. ;-) I've checked out the example apps (none have
implementations like what I need). I've also read and re-read all the
Cocoa bibles. The problem is that I feel this area is glanced over a
little too quickly in all the documentation and all the better books.
I'd *LOVE* the authors to go more in-depth on these issues in the
next revision (I'm eyeing you, Scott :-) ), but until then, does anyone
have any links to good examples, articles, tutorials,
Matrix-style-knowledge-loaders?
Thanks!
- J
