Eclipse binding SWT button selection to a model function

I've been learning some eclipse data binding, it's been fairly simple to bind data from a model to the UI. What I'm wondering is if there is some way to bind the selection (event?) on an SWT button, or combobox, etc. to a method on my model.

I've just been manually creating a connection using addSelectionListener in my window code which simply calls the function on my model object.

No it's not. Databinding is to synchronize values between different objects.

What you can do is to bind the boolean select-state of a widget to a property (not a method) in your model. For example:

// observe the widget
ISWTObservableValue uiObs = WidgetProperties.selection().observe(myButton);
// observe the 'selected' property of 'myObject'
IObservableValue modelObs = BeansObservables.observeValue(myObject, "selected");
// bind
ctx.bindValue(uiObs,modelObs);
