Widget Example: JButtons

• The java.swing.JButton class implements a state version of a java.swing.AbstractButton. Many methods come from the abstract class:

  • A variety of constructors (Strings, Icons, etc.);
  • setRolloverEnabled(boolean);
  • setIcon(Icon);
  • setRolloverIcon(Icon);
  • setActionCommand(String); -- an extra String tacked onto the event that gets fired!
  • setContentAreaFilled(boolean) -- transparency for icons!
  • setModel(ButtonModel); -- sets the ‘type’ of Button (you can define your own Button behaviors!)
  • setMnemonic(char/int); -- set mnemonics for button
