getActionName

public abstract String getActionName()

getActionDesc

public abstract String getActionDesc()

getRenderer

public abstract Renderer getRenderer()

Each bean has one Renderer, made current when Action is called

getAction

public 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:

the Action to be called.

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Add a PropertyChangeEvent Listener.

protected void firePropertyChangeEvent(Object source,
                           String propertyName,
                           Object oldValue,

makeMapSelectButton

public static PopupMenu makeMapSelectButton()

Convenience routine to make a button with a popup menu attached. to use:

      thredds.ui.PopupMenu mapBeanMenu = MapBean.makeMapSelectButton();
      AbstractButton butt = (AbstractButton) mapBeanMenu.getParentComponent();
      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();
         }
       }
     });
