Method Detail

perform

public void perform(IlvDiagrammerAction action,
                    IlvDiagrammer diagrammer,
                    ActionEvent event)
             throws Exception

This method is called when an IlvDiagrammerAction is performed.

The default implementation calls the perform(IlvDiagrammerAction, IlvDiagrammer, ActionEvent) method of the action.

Parameters:

action - The action that is being performed.

diagrammer - The diagram component on which the action is being performed.

event - The AWT action event that causes the action to be performed.

Throws:

Exception

update

public void update(IlvDiagrammerAction action,
                   IlvDiagrammer diagrammer)
            throws Exception

This method is called when the state (enabled/disabled, selected/unselected) of an IlvDiagrammerAction is queried. The implementation of this method should call the AbstractAction.setEnabled(boolean) and ComponentAction.setSelected(boolean) methods of the action.

The default implementation calls the update(IlvDiagrammerAction, IlvDiagrammer) method of the action.

Parameters:

action - The action that is being updated.

diagrammer - The diagram component for which the action is being updated.

Throws:

Exception

perform

public final void perform(ilog.views.util.swing.context.ComponentAction action,
                          Component target,
                          ActionEvent event)
                   throws Exception

Performs the action on the target component. Calls perform(IlvDiagrammerAction, IlvDiagrammer, ActionEvent) if the input is a diagrammer action with a diagrammer component.

Overrides:

perform in class ilog.views.util.swing.context.ComponentAction.Handler

Parameters:

action - The action that is being performed.

target - The component on which the action is being performed.

event - The AWT action event that causes the action to be performed.

Throws:

Exception

update

public final void update(ilog.views.util.swing.context.ComponentAction action,
                         Component target)
                  throws Exception

Updates the action with respect to the target component. Calls update(IlvDiagrammerAction, IlvDiagrammer) if the input is a diagrammer action with a diagrammer component.

Overrides:

update in class ilog.views.util.swing.context.ComponentAction.Handler

Parameters:

action - The action that is being updated.

target - The component for which the action is being updated.

Throws:

Exception
