EditableChoiceStyle

public class ChoiceStyle
extends ParameterEditorStyle

This attribute annotates user settable attributes to specify an uneditable combobox style for configuring the containing attribute. An uneditable combobox is restricted to only the values specified as the combobox options. No arbitrary value can be entered. For an editable combobox, use EditableChoiceStyle instead. The choices that are presented in the combobox are given by a set of attributes implementing the Settable interface, such as StringAttribute, contained by this style.
