Interface IViewerValueProperty

All Superinterfaces:: org.eclipse.core.databinding.property.IProperty, org.eclipse.core.databinding.property.value.IValueProperty

All Known Implementing Classes:: ViewerValueProperty

public interface IViewerValueProperty
extends org.eclipse.core.databinding.property.value.IValueProperty
extends org.eclipse.core.databinding.property.value.IValueProperty

IValueProperty for observing a JFace viewer

Since:: 1.3
Restriction:: This interface is not intended to be implemented by clients.

Method Summary

IViewerObservableValue observe ( Viewer viewer)
Returns an IViewerObservableValue observing this value property on the given viewer

IViewerObservableValue observeDelayed (int delay, Viewer viewer)
Returns an IViewerObservableValue observing this value property on the given viewer, which delays notification of value changes until at least delay milliseconds have elapsed since that last change event, or until a FocusOut event is received from the viewer's control (whichever happens first).

Method Detail

observe


IViewerObservableValue observe(
Viewer viewer)

Returns an IViewerObservableValue observing this value property on the given viewer

Parameters:: viewer - the source viewer
Returns:: an observable value observing this value property on the given viewer

observeDelayed


IViewerObservableValue observeDelayed(int delay,
                                      
Viewer viewer)

Returns an IViewerObservableValue observing this value property on the given viewer, which delays notification of value changes until at least delay milliseconds have elapsed since that last change event, or until a FocusOut event is received from the viewer's control (whichever happens first).

This method is equivalent to ViewersObservables.observeDelayedValue(delay, observe(viewer)).

Parameters:: delay - the delay in milliseconds.; viewer - the source viewer
Returns:: an observable value observing this value property on the given viewer, and which delays change notifications for delay milliseconds.
