Selecting a Container

Common Top-Level Containers:

Frame -- familiar window object with scrollbars, etc.

Window -- more basic window object, no scrollbars, etc.

Applet -- embedded byte code inside HTML document.

Instantiation:

Note: Frames and Windows not self-disposing.

(GUI components use more than just memory: Only memory

is garbage-collected by the JVM. Other resources have to

be reclaimed manually by dispose() )

Frame myFrame = new Frame();

myFrame.setLayout(new FlowLayout());

myFrame.add(myButtonInstance);

. . .

/* when done */

myFrame.dispose();

/* (event handling to come shortly . . .) */
