Interface IChangePreviewViewer

  • public interface IChangePreviewViewer
    Viewer to present the preview for a Change.

    Viewers are associated with a change object via the extension point org.eclipse.ltk.ui.refactoring.changePreviewViewers. Implementors of this extension point must therefore implement this interface.

    To ensure visual consistency across all provided preview viewers the widget hierarchy provided through the method createControl(Composite) has to use a ViewForm as its root widget.

    Clients of this interface should call createControl before calling setInput.
