public interface AppearanceControl
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.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<>();
