Understanding 32bit Mac VST Integration


I just browsed through the platform specific JUCE code and stumbled over the VST2 implementation for Mac 32bit (Carbon). I wonder if somebody (who has more experience then me with Mac development) can explain what is happening there. The VST interface supplys a WindowRef (Carbon) and for what I understand, this reference is used to create a NSWindow (Cocoa) which is then simply put over the Carbon View. Does the newly created Cocoa window (via" initWithWindowRef") get all necessary events? (Mouse, Drawing, Keyboard) Or do I miss something? As I understand it, only the position of the window has to be adjusted when the dummy window (or view) position is changed.

The cocoa window gets all the necessary events without the host needing to pass them on (as was the case in Carbon).
