getAction

public javax.swing.Action getAction()

Construct the Action that is called when this bean's menu item/buttcon is selected. Typically this routine is only called once when the bean is added. The Action itself is called whenever the menu/buttcon is selected. The action should have NAME, SMALL_ICON and SHORT_DESC properties set. The applications uses these to put up a buttcon and menu item. The actionPerformed() method may do various things, but it must send a PropertyChangeEvent with newValue = Renderer.

Returns:

      addToMenu (butt);

      // add map beans here
      mapBeanMenu.addAction( mb.getActionDesc(), mb.getIcon(), mb.getAction());

      mb.addPropertyChangeListener( new PropertyChangeListener() {
       public void propertyChange( java.beans.PropertyChangeEvent e) {
         if (e.getPropertyName().equals("Renderer")) {
           mapRender = (thredds.viewer.ui.Renderer) e.getNewValue();
           mapRender.setProjection( np.getProjectionImpl());
           redraw();
