public abstract class EnumControl extends Control
EnumControlprovides control over a set of discrete possible values, each represented by an object. In a graphical user interface, such a control might be represented by a set of buttons, each of which chooses one value or setting. For example, a reverb control might provide several preset reverberation settings, instead of providing continuously adjustable parameters of the sort that would be represented by
Controls that provide a choice between only two settings can often be implemented
instead as a
, and controls that provide
a set of values along some quantifiable dimension might be implemented
instead as a
FloatControl with a coarse resolution.
However, a key feature of
EnumControl is that the returned values
are arbitrary objects, rather than numerical or boolean values. This means that each
returned object can provide further information. As an example, the settings
control are instances of
that can be queried for the parameter values
used for each setting.
