Why use the QCCompositionParameterView Delegate for that when you can inspect the ports directly from and instantiated QCRenderer/ QCCompositionRenderer by grabbing the attributes dictionary and looking for the QCPortAttributeTypeKey, QCPortAttributeMinimumValueKey and QCPortAttributeMaximumValueKey key?
The keys are the same either way -- you're right though, using the raw QCRenderer would be simpler, and appears to all be documented. I hadn't looked much at QCCompositionRenderer to see that yet.
However, "QCPortAttributeDefaultValueKey" doesn't seem to be set in any of my renderers -- I'm assuming that that would be set to whatever the keyed-in value when saving the composition, but this is what I get:
3/23/09 2:49:09 AM freqTest[33313] attr: {
QCCompositionAttributeHasConsumersKey = 1;
QCCompositionAttributeIsTimeDependentKey = 1;
QCCompositionAttributeSourceKey = Data;
"labeled_input" = {
QCPortAttributeMaximumValueKey = 2;
QCPortAttributeMenuItemsKey = (
alice,
bob,
charlie
);
QCPortAttributeMinimumValueKey = 0;
QCPortAttributeNameKey = "labeled input";
QCPortAttributeTypeKey = QCPortTypeIndex;
};
"limited_Input" = {
QCPortAttributeMaximumValueKey = 64;
QCPortAttributeMinimumValueKey = 0;
QCPortAttributeNameKey = "limited Input";
QCPortAttributeTypeKey = QCPortTypeIndex;
};
"unlimited_Input" = {
QCPortAttributeMinimumValueKey = 0;
QCPortAttributeNameKey = "unlimited Input";
QCPortAttributeTypeKey = QCPortTypeIndex;
};
}
limited_Input is set to 22, and labeled_input is set to "bob" in the
composition, but that isn't reflected here (or in the parameters view,
which is just a rehash of this data, as you've demonstrated :)
