Hi Stefan,

I feel a little confused at the moment. I've been building some
little AUs with a Cocoa view. So far everything is fine, but some
host are not able to use Cocoa views. Even Logic 7.1 doesn't seem
to handle that without side effects (I've already been writing to
this list regarding that a few month ago) but anyway...
To me it seem that you also have to provide a Carbon view with your
AUs in order to guarantee a professional looking and usable plug
in. The trouble I have is that it's quite hard to find good
information to get started with Carbon. I often just find links to
tutorials on the apple website, that have been removed sometimes in
the past. Furthermore a lot of people tell, that it's better to not
use carbon any more.
So, what to do? Is there a simple solution, or where do I find good
resources or even better tutorials to get started with the carbon
thing - especially the stuff I need to know for a carbon view?
A possible solution for you could be to wrap up your Cocoa view in a
Carbon view.
Have a look here, there's a dedicated section about "Using a Cocoa
User Interface in a Carbon Application":
http://developer.apple.com/documentation/Cocoa/Conceptual/
CarbonCocoaDoc/
Remember that you're living in a plug-in, not an application, so if
you're running in a Carbon host you must make sure that the Cocoa
runtime stuff is started up as needed.
Also, pay attention on when to provide autorelease pools (because
Cocoa always assumes that there is one).
Also make sure to read this:
/Developer/Examples/CoreAudio/Documentation/AudioUnits/
CarbonViewCocoaWindow.rtfd
Even though it's about the other way round (wrapping Carbon in
Cocoa), it is specific to AUs, explains the basic concept of bridging
between Cocoa and Carbon and provides a couple of useful links.
We are using the wrapping approach to handle Cocoa AU views for
Logic, so if you get stuck on your way I might be able to help.
However as you've noticed there are a few glitches with this
technology even in Logic (though 7.2.1 is a lot better that 7.1 in
this regard, so you should upgrade), but I still think that while
it's certainly not a perfect solution it may still be good enough for
your plug-in to justify not doing a dedicated Carbon version of your UI.
Best,
Stefan
