private ActionDeleteFromDiagram()
Method Detail

shouldBeEnabled

public boolean shouldBeEnabled()
Tells if this action shall be enabled or not.

Remove from diagram is not allowed when the diagram is a statechart. This because the diagram = the statemachine according UML. Use a submachinestate to split a big diagram in parts instead. And because it leads to unsolvable problems with concurrency.

Overrides:
shouldBeEnabled in class UMLAction
Returns:
true if it shall be enabled.

actionPerformed

public void actionPerformed(ActionEvent ae)
Description copied from class: UMLAction
Perform the work the action is supposed to do. This method needs to be overridden by all actions, since it only shows a fake progressbar...

Specified by:
actionPerformed in interface ActionListener
Overrides:
actionPerformed in class UMLAction
See Also:
ActionListener.actionPerformed(java.awt.event.ActionEvent)

getSingleton

public static ActionDeleteFromDiagram getSingleton()
Returns:
Returns the singleton.
