If I were in your shoes, I would probably focus on the least-common-
denominator and just use QuickTime directly for most functionality.
The work required to support two different development paths, one
with QTKit and one without, seems like time that could be spent
simply developing your own Cocoa interfaces to QuickTime.
If you can drop support for pre-10.4, then I'd say go with QTKit,
otherwise probably just look forward to a day when you can use it :)
2) whenever I try to make connections from menuItems with
application controller class that is application object.I get in
the actions list the one's available in first responder. and if it
is so then where to write that imlementation? there are some
predefined action items like copy,cut etc.
where exactly their implementations will be?
can I add some action items to first responder ? if yes where to
implement them?
Read this:
http://developer.apple.com/documentation/Cocoa/Conceptual/
BasicEventHandling/Concepts/AboutRespChain.html
The First Responder is a "Stand-In" Nib object, that really means
"send it to the first object in the responder chain that implements
the method. You can examine the responder chain in the documentation
linked above. Basically you just implement the method in an object
that falls into the chain (e.g. your application's delegate class)
and it magically gets called.
To add new actions to the first responder just double-click its icon
in IB to bring up the class inspector. Here you can add new actions
as you would for any real class.
