See Also:

DiagramAction.createTargetRequest()

isSelectionListener

protected boolean isSelectionListener()

Description copied from class: DiagramAction

Does this action need to listen to selection change events? If the enablement state of the context menu or the operation set depends on what is selected in a diagram, then this needs to return true. If this action targets the diagram only, then it should return false.

Actions that are only contributed to the popup menu (and not toolbar or main menus) will not receive selection events at all. The refresh() method will be called when the context menu is about to show.

Specified by:

isSelectionListener in class DiagramAction

updateTargetRequest

protected void updateTargetRequest()

Description copied from class: DiagramAction

updates the target request. Clients should call this method whenever the request is expected to be changed

Overrides:

protected DestroyElementRequest getDestroyElementRequest()

Helper method for getting the DestroyElementRequest

Returns:

the DestroyElementRequest

getEditingDomain
