public class LwFrame

extends java.awt.Frame

implements java.awt.event.FocusListener

The class inherits java.awt.Frame components and it should be used instead the java.awt.Frame to create a lightweight application. The class provides root light weight component that has to be used as top-level container for all other lightweight components. The root is laidout with java.awt.BorderLayout inside the frame using "Center" constraint. The sample below illustrates the frame component usage:

    ...
    LwFrame frame = new LwFrame();
    frame.setSize(400, 400);
    LwContainer root = frame.getRoot();
    root.add (new LwButton("Cancel"));
    root.add (new LwButton("Ok"));
    ...
    frame.setVisible(true);
    ...
