We follow the model-view-controller pattern extensively in the UI. All controllers should derive from this class. A controller is resposible for all event handlers for a JETAPanel (JETAPanels handle only layout and view logic). This controller class also supports disabling listeners. This is useful when updating a view with components that fire events when changed programmatically such as JComboBoxes. See <A HREF="../../../../../com/jeta/open/gui/framework/JETAController.html#enableEvents(boolean)"><CODE>enableEvents(boolean)</CODE></A>. Usage: <pre> class MyController extends JETAController { public MyController( JETAContainer view ) { super(view); // assign a button handler. If the view has a menu and toolbar button // for the same command, this assignAction method will install handlers // on both. assignAction( MyViewNames.ID_LOGIN_BUTTON, new LoginAction() ); // assign other listeners } public class LoginAction implements ActionListener { public void actionPerformed( ActionEvent evt ) { MyFrame frame = (MyFrame)getView(); //... } } } </pre><P><P><HR><P><!-- ========
