[Databinding] Custom control [message #447772]

I'm trying to bind value in com.gface.custom.SearchBox SWT component with String value in model object. I did this same way like I did for Text component. But I got an exception when this code was executed: org.eclipse.jface.internal.databinding.provisional.BindingEx ception: could not find updatable for SearchBox {}

What is a proper way to bind this component with a value in a model? Same exception I got with DatePickerCombo SWT component.

Miroslav,
You'll need to create an implementation of IObservable for your widget
and make it available to the binding process. For Text the IObservable
implementation is TextObservableValue. If you open
SWTObservableFactory and search for "TextObservableValue" you'll find
how and where the binding is created. Each widget needs its own
implementation of IObservable so that notifications can be fired at the
opportune time for the Widget to integrate into the framework.

Hope that helps.
