I am trying to follow "Binding Controls to Input Ports" of Quartz Composer Programming Guide.
The document says :
5.Click “Bind to” and then choose Patch Controller in the “Bind to” popup menu.
6.Enter patch in the Controller Key text field.
7.Enter text.value in the Model Key Path text field.
In my project of Xcode (4.2 &) 4.3, the Controller Key text field is disabled. The Model Key Path text field requires an object of QCPatch class, which I don't think I have a clue.
Should I install Xcode 3.x and handle this & convert to 4.x? Any advice ?
