public class DiagramComposite
extends GraphicalComposite
implements IDiagramContainerUI

An SWT composite that can display a Graphiti diagram. This implementation is based on a custom GraphicalComposite class that works much like the GEF GraphicalEditorWithFlyoutPalette class. A DiagramComposite can be used anywhere a regular SWT Composite can. A DiagramComposite can participate in a parent transaction or create one of it's own. If the DiagramComposites is managing it's own transaction, it is up to the enclosing workbench part to call the appropriate methods on the composite.

public void setInput(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain,
                     IDiagramEditorInput input)

initializeGraphicalViewer

public void initializeGraphicalViewer()

Description copied from class: GraphicalComposite

Override to set the contents of the GraphicalViewer after it has been created.

Specified by:

initializeGraphicalViewer in interface IDiagramContainerUI

See Also:

#createGraphicalViewer(Composite)

configureGraphicalViewer

public void configureGraphicalViewer()

Description copied from class: GraphicalComposite

Called to configure the graphical viewer before it receives its contents. This is where the root editpart should be configured. Subclasses should extend or override this method as needed.

Specified by:

Since:

0.12

refreshTitle

public void refreshTitle()

Description copied from interface: IDiagramContainer

Refreshes the title text of this container. It depends on the container type what and if anything is refreshed, for an editor e.g. the part tab will be refreshed.

Specified by:
