org.eclipse.ltk.ui.refactoring
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.

Since:
3.0
