Interface AppearanceControl

All Superinterfaces:
AppearanceControl
All Known Implementing Classes:
AppearanceControlComboBox, AppearanceControlTextField, ColorControlPanel, OtsControlPanel.ClockLabel, OtsControlPanel.TimeEdit
public interface AppearanceControl extends AppearanceControl
This interface allows on screen items to not obtain colors and/or the font from an Appearance. This can be useful for items where considering only a background and a foreground color is not sufficient, possibly creating unreadable or otherwise unpleasant on screen items.

The default implementation of the methods in this interface return false, meaning the Appearance is completely ignored. In order to ignore it only partially, some methods should be overridden to return true. An example of this is given below, which will only allow the font of the Appearance. It also shows a convenient way to implement this interface when using default on screen items using a local class. 
 class AppearanceControlComboBox<T> extends JComboBox<T> implements AppearanceControl
 {
     public boolean isFont()
     {
         return true;
     }
 }

 JComboBox<String> comboBox = new AppearanceControlComboBox<>();
