Class ComponentLink

java.lang.Object

no.g9.client.support.ComponentLink

public class ComponentLink
extends Object

Utility class for linking two gui components together. The link is a one-way link, so that the state in the from-component is reflected in the to-component.

It is possible to create more than one link from or to a component, and set up links both ways between two components, or a graph for that matter.

The link between components are created by simply calling the overloaded link-method, e.g: JTextField f1, f2; ComponentLink.link(f1, f2);

The possible link types are:

• text -> text
• combo -> text
• combo -> combo
• radio button -> radio button
• radio button -> check box
• check box -> check box
• check box -> radio button

This list might be extended in future releases.
