Just reposting in hopes of soliciting some help (it's the last time, I
promise :-)
Hi all:
So this is a last ditch effort on my part to resolve an issue I've
been having. I am using a Carbon (I know, I know, Cocoa is the wave
of the future ... whatever ;-) and quicktime frameworks to implement
a GUI. I am having mixed results, with some hosts, including DP and
Bidule, demonstrating proper functioning. But in AULab the controls
do not update as I would expect. What is especially weird is that
the parameters are being changed in accordance with my mouse clicks
and drags -- I can hear the changes in the sound. However, the GUI
is not redrawing to reflect this -- as far as I know, this is only
happening in AULab, but it still has me worried. Everything in
auval passes, including the custom carbon view. Has anyone had
experience with this before?

OK maybe I can clarify what's going on here, and I'll be able to
facilitate better interaction.
I am using Carbon Event Manager Functions (derived from Urs'
CAUGuiSDK) which registers a Toolbox Object Class and passes reference
to a global callback function. This callback function receives user
commands and handles the drawing. When the callback is made from the
host, all of the drawing is done properly and as expected in some
hosts. But in other hosts (AULab and AudioUnitsHosting included :-/ )
the callback is not being made on mouse commands. Therefore I can
change a parameter, see no visual alteration (no callback being made),
close and reopen the GUI and the controls will be at the proper
position, I guess b/c re-initializing the GUI is causing a callback,
so all of my draws are being handled. I get proper functioning (mouse
control triggers callback which does the drawing) in Peak 4 and in
Bidule 0.96.
Please, any advice would be greatly appreciated!
Regards
~chris b
