Class View

  • Direct Known Subclasses:
    FrameView
    public class View
extends AbstractBean
    A View encapsulates a top-level Application GUI component, like a JFrame or an Applet, and its main GUI elements: a menu bar, tool bar, component, and a status bar. All of the elements are optional (although a View without a main component would be unusual). Views have a JRootPane, which is the root component for all of the Swing Window types as well as JApplet. Setting a View property, like menuBar or toolBar, just adds a component to the rootPane in a way that's defined by the View subclass. By default the View elements are arranged in a conventional way:
    • menuBar - becomes the rootPane's JMenuBar
    • toolBar - added to BorderLayout.NORTH of the rootPane's contentPane
    • component - added to BorderLayout.CENTER of the rootPane's contentPane
    • statusBar - added to BorderLayout.SOUTH of the rootPane's contentPane

    To show or hide a View you call the corresponding Application methods. Here's a simple example: 

     class MyApplication extends SingleFrameApplication {
     @ppOverride protected void startup() {
         View view = getMainView();
         view.setComponent(createMainComponent());
         view.setMenuBar(createMenuBar());
         show(view);
     }
 }

    The advantage of Views over just configuring a JFrame or JApplet directly, is that a View is more easily moved to an alternative top level container, like a docking framework.

        The main {JComponent} for this View.
        Returns:
        The component for this View
        See Also:

      • setComponent

        public void setComponent​(javax.swing.JComponent component)
        Set the single main Component for this View. It's added to the BorderLayout.CENTER of the rootPane's contentPane. If the component property was already set, the old component is removed first.
