Model View Controller Framework

[John Vorwald]

I had several number crunching classes that I"m trying to hook together in a multi-thread application. I'm implementing the model/view/controller framework, but have a question about a how to handle user input. Currently, the app window displays information from the different Views in tabbed panels. This is fine for showing output through the view classes. But, how to handle input to the model classes.

The view interface is

public interface View
{
    void addPropertyChangeListener( Controller aController );
    void removePropertyChangeListener( Controller aController );
    void modelPropertyChange( PropertyChangeEvent aEvt );
    String getName();
    String tabTitle();
    String tabTip();
}

The Model interface is

public interface Model extends Runnable {
    void addPropertyChangeListener( Controller aController );
    void removePropertyChangeListener( Controller aController );    
    String getName();
}

It seems that the only way the View can communicate back to the Model is by passing a Model as an argument during construction.
Any other suggestions/recommendations?

Never mind, I just had to implement the addPropertyChangeListener method in the View so that the Controller was accessible from inside the View.
