Class CustomChoice

java.lang.Object

net.coderazzi.filters.gui.CustomChoice

All Implemented Interfaces:

java.io.Serializable

public abstract class CustomChoice
extends java.lang.Object
implements java.io.Serializable

Class to specify a custom filter in the choices list.

A custom choice allows to specify custom filters that can be selected as a choice in the filter editor. A custom choice is associated always to a text, which the user can input to select the given choice.

It is also possible to specify how the custom filter is rendered; by default it is displayed the icon -if provided-, and the text, unless the user provides a custom renderer.

The order of the custom choices on the choices list can be modified with the precedence attribute. By default, custom choices are sorted by their textual representation. If a precedence is given, lower values are displayed first.
