ActionMaps in java

Question

public class XXX 
{
    public static void main(String args[]) {
        JComponent comp = new JTable(); // some panel or table
        comp.getInputMap().put(KeyStroke.getKeyStroke("F4"), "xxxaction");
        comp..getActionMap().put("xxxaction", new XXXAction());
    }

    public class XXXAction extends AbstractAction
    {
        @Override
        public void actionPerformed(ActionEvent e)
        {
             // Something;
        }
    }
}

Is there a way to execute the invoked action XXXAction() without pressing 'F4' using the ActionMap lookup??

Many thanks in advance!!!

Answer 1

I can suggest two possible ways:

1. Register your action with a Component such as a JButton. That way the Action will be invoked when you manually click the button with the mouse.
2. Define a method invokeAction() on your class XXX that calls the action, either by retrieving the action from the ActionMap via its key, or by retaining an explicity instance variable reference to it as well as placing it in the ActionMap.

Answer 2

General code would be:

Action action = component.getActionMap().get("...");

if (action != null)
{
    ActionEvent ae = new ActionEvent(component, ActionEvent.ACTION_PERFORMED, "");
    action.actionPerformed( ae );
}

You will need to know if a String value is required for the ActionEvent.
