Constructor Detail

Frame

public Frame()
Constructs a new instance of Frame that is initially invisible.

finalize in class Object

constructComponentName

String constructComponentName()
Construct a name for this component. Called by getName() when the name is null.
Overrides:
constructComponentName in class Window

addNotify

public void addNotify()
Creates the Frame's peer. The peer allows us to change the look of the Frame without changing its functionality.
