Class UIAction

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.util.EventListener, javax.swing.Action

    public abstract class UIAction
    extends java.lang.Object
    implements javax.swing.Action
    UIAction is the basis of all of basic's action classes that are used in an ActionMap. Subclasses need to override actionPerformed.

    A typical subclass will look like:

        private static class Actions extends UIAction {
            Actions(String name) {
                super(name);
            }
     

    public void actionPerformed(ActionEvent ae) { if (getName() == "selectAll") { selectAll(); } else if (getName() == "cancelEditing") { cancelEditing(); } } }

    Subclasses that wish to conditionalize the enabled state should override isEnabled(Component), and be aware that the passed in Component may be null.
