First, let me say I'm a bit annoyed by the responses some people
receive on this list when they ask a valid question. Allan, I'm not
specifically attacking you, but your response wasn't particularly
helpful. See below.
If it is not meant for me: do not follow up with such a rant before a
reply to me!
[...] when someone states up-front that he or she DID RTFM and to
please not respond with RTFM ...
Providing a link to documentation is not the same as saying RTFM. Also,
I have been working with Cocoa for 1-2 years now, read much of the
documentation many times, still I find new pieces of information now
and then!
What gets me even angrier is when someone asks a valid question and
is met with "What? Why would you want to do this? Why? MY GOD, WHY?!"
Angry? There are several reasons for such a question namely curiosity
and that it sounds like the OP is going at his problem the wrong way,
but he himself did not provide any context -- so let us see if we can
lure it out of him. Anyway it's easier to answer questions given
context.
See
http://developer.apple.com/documentation/Cocoa/Conceptual/DrawViews/
index.html
As I specifically stated in my original post, I have read this
several times over.
No, you said "I have RTFM". Does that include *all* documents at
developer.apple.com? And I explicitly listed two sections from the
above document, namely those about scroll views and clip views.
Your question was: "I can't seem to find a comprehensive,
easy-to-digest explanation of: How NSScrollView and NSClipView objects
work together". That is explained in the document I referred to.
If you want more specific help, ask more specific questions! If you do
not want to be pointed at resources you have already exhausted, then
list exactly what you have already read (and perhaps how you
interpreted it).
Would you know of any *other* resources that further explain this?
No, I do not know of any other resources than TFM which explains these
concepts.
Actually using iMovie and playing with it, I can see that the
original view remains in the clip palette until it's dropped on the
timeline, then it is 'moved'. But now what about the
confining-to-the-timeline question? The method I'm using (the
NSContainsRect() hit test thing) doesn't seem right.
I do not have iMovie, so I do not know the exact behavior. However,
with Cocoa there is no way to limit the actual movement of the dragged
image, only the visual feedback given by dragging it around -- if you
desperately need to restrain the movement of the dragged object, you'll
need to implement pretty much everything yourself. I would think the
best way is to open a (transparent) window and move that around.
Again, I'd REALLY appreciate someone directing me to further reading
on all this. At *least* a different perspective. I can't stress enough
how things can be hard to grasp for some people until it's explained a
little differently ...
Please understand that it is just as hard for us to know at what level
your understanding is, what exactly you need help with, what you have
already tried etc. when you do not explicitly state these things.
I really think your letter is both immature and offensive, even if it
was not directly meant for me -- you really ought to ask yourself why
you get unsatisfying answers and try to improve your own
question-asking skills instead of sending such stupid rants to the
list, which will just ensure you even less answers in the future!
