Window and Frame for Foil 54
1 Up to now, we have described how to build typical Applet panels inside browser window. There are classes that allow one to generate complete windows separately from the browser window
2 Window Class has subclasses Frame and Dialog
3 Create a window with a given title:
    • Frame f = new Frame("TitleofWindow");
  • Frames appear and disappear by using the method setVisible:
    • f.setVisible(true); // makes the window appear on the screen
    • f.setVisible(false); // makes the window disappear from the screen
  • Note Frame is a Container and can thereof be defined hierarchically with components that are laid out by LayoutManagers
  • Note a Frame in Java is NOT THE SAME as a frame in HTML
