Working on a small QC host application , I can't find the way to have
QCPortAttributeMenuItemsKey to work .
Here is the my code section ( assuming _renderer is a QCRenderer object) .
NSString* inputKey;
NSDictionary* inputAttributes;
NSString* type;
NSArray* inputList = [[_renderer composition] inputKeys];
for(int i = 0; i < [inputList count]; ++i)
{
// gets inputKey , and type for each input ports
inputKey = [inputList objectAtIndex:i];
inputAttributes = [[[_renderer composition] attributes]
objectForKey:inputKey];
type = [inputAttributes objectForKey:QCPortAttributeTypeKey];
if([type isEqualToString:QCPortTypeIndex])
{
NSLog( @" is class of %@", NSStringFromClass
([[inputAttributes objectForKey:QCPortAttributeMenuItemsKey] class]));
//index has labeled indexes
if ([[inputAttributes
objectForKey:QCPortAttributeMenuItemsKey] count] != 0)
{
//Do something
}
}
Whatever composition with a published labeled indexes input , I'm passing
through .. the NSLog returns that [inputAttributes
objectForKey:QCPortAttributeMenuItemsKey] is null .
What would be the way , to track when a composition has a published labeled
indexes input ?
Thanks !!
