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
|
|
Window Class has subclasses Frame and Dialog
|
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
