I am working on a NSSlider similar to the one used in iMovie to scrub
through the video (the preview one under the big screen). I have used
the weekend to become familiar with the NSSlider and NSSliderCell and
the various NSRects to manipulate--being that I am fairly new to obj-c,
quicktime and the mac for that matter. I want to make sure that I am
not missing something that's already available. So, I want to see if
anyone else has done something like this. I saw a post from February
on the archives where Cyril was subclassing NSSliderCell. If something
already exists, or I am going about this the wrong way I am hoping
someone will speak up.
After I have got it working like iMovie, the next step will be to allow
it to control 2 or more video tracks simultaneously. I haven't decided
if I am going to have those tracks be in the same movie or if I am
going to have a movie object for each track, not certain the best way
to do it. Each video needs to appear in it's own NSWindow. But,
that's second. I have read a little about creating a Movie Controller,
but to be honest it looks a little frightening. So, I am just taking
this one step at a time, first the single NSSlider control, then take
over the world. : )
Anybody else on the cocoa list or the quicktime list doing something
similar?
Thanks,
Pete Gordon
