Class State<T extends JComponent>

Represents a built in, or custom, state in Nimbus.

Synth provides several built in states, which are:

• Enabled
• Mouse Over
• Pressed
• Disabled
• Focused
• Selected
• Default

However, there are many more states that could be described in a LookAndFeel, and it would be nice to style components differently based on these different states. For example, a progress bar could be "indeterminate". It would be very convenient to allow this to be defined as a "state".

This class, State, is intended to be used for such situations. Simply implement the abstract #isInState method. It returns true if the given JComponent is "in this state", false otherwise. This method will be called many times in performance sensitive loops. It must execute very quickly.

For example, the following might be an implementation of a custom "Indeterminate" state for JProgressBars:

public final class IndeterminateState extends State<JProgressBar> {
         public IndeterminateState() {
             super("Indeterminate");
         }

         @Override
         protected boolean isInState(JProgressBar c) {
             return c.isIndeterminate();
         }
     }
