| Is it possible to set the class of a return object when getProperty is called? I've been working on adding a Quartz Composer view, and have implemented a method to get the values of QC output ports. The SC side looks like this: getOutputValue{|key| ^this.getProperty(\getOutputValue, key.asSymbol); } The key is the name of the port to be read. This works fine for ints and floats, but if I want to get a Color: if (strcmp(name, "getOutputValue")==0) { PyrSymbol *keysymbol; int err = slotSymbolVal(slot, &keysymbol); if (err) return err; NSString *key = [[NSString alloc] initWithCString: keysymbol->name encoding: NSASCIIStringEncoding]; if(![[mQCView outputKeys] containsObject: key]) { [key release]; return errFailed; } NSDictionary *outputAttributes = [[mQCView attributes] objectForKey: key]; NSString *type = [outputAttributes objectForKey:QCPortAttributeTypeKey]; ... else if([type isEqualToString:QCPortTypeColor]) { NSColor *val = [mQCView valueForOutputKey: key]; SCColor rgb = SCMakeColor([val redComponent], [val greenComponent], [val blueComponent], [val alphaComponent]); err = setSlotColor(slot, &rgb); [key release]; return errNone; } ... it fails with errWrongType at setSlotColor because the slot is of the wrong type. Can one change this and if so, how? S. |
