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
.
