LookAndFeel

public LookAndFeel()

Method Detail

bind

public void bind(Component cmp)

Every component binds itself to the look and feel thus allowing the look and feel to customize the component. Binding occurs at the end of the constructor when the component is in a valid state and ready to be used. Notice that a component might be bound twice or more and it is the responsibility of the LookAndFeel to protect against that.

Parameters:: cmp - component instance that may be customized by the look and feel

uninstall

public void uninstall()

Invoked when a look and feel is removed, allows a look and feel to release resources related to binding components.
