We broke out the factory preset property from the Cocoa generic

will see the same view as AU Lab displays.
I see what you are suggesting. It seems I need to do something like
this:
if there is a non-generic carbon view:
display it
else
display cocoa view, whether generic or not
Unfortunately, I am stuck on the very first step: how do I
distinguish carbon generic views from non-generic views? Does it
have to do with the number of views associated with the
kAudioUnitProperty_GetUIComponentList property? This appears to be
undocumented.
In general an AU won't publish any components in its GUI list if it
doesn't have custom views. Some of Apples' AUs do publish the carbon
generic view (because it has some features that the host app generic
views don't have).
In AULab if the AU publishes a carbon custom view, we'd also filter
it, so that if it had a component fields of:
guiComponentFromAU.componentType *is*
kAudioUnitCarbonViewComponentType;
guiComponentFromAU.componentSubType *is*
kAUCarbonViewSubType_Generic;
guiComponentFromAU.componentManufacturer *is*
kAudioUnitManufacturer_Apple;
we know it is the generic view and just use the cocoa one instead
(same idea as what you are doing below)
Bill
FWIW, I can easily see how to distinguish between generic and non-
generic cocoa views, so my logic right now is more like this:
if there is a non-generic cocoa view:
display it
else
display carbon view, whether generic or not
