Class JTreeSelectionCommandAdapter

java.lang.Object
  com.sdm.quasar.client.core.commands.AbstractCommandAdapter
      com.sdm.quasar.client.swing.commands.adapters.JTreeSelectionCommandAdapter

All Implemented Interfaces:

CommandAdapter, Disposable

public class JTreeSelectionCommandAdapter

extends AbstractCommandAdapter

The JTreeSelectionCommandAdapter is an adapter between a JTree and a Command:

It trigges the Command, when a TreeSelectionEvent is fired.

Caution: Be careful using this adapter for two reasons:

• The command is triggered when ever the selection is changed, e.g. by the user as well as from your program code
• In conjunction with data binding to the selected object you can't be sure, that your data has been updated before the command is triggered.

Description copied from interface: Disposable

Disposes the component.

Important:
This method is called by an administrating component and must never be called directly.

The implementation should release any resources or objects allocated and any services registered. Furthermore, this method should be developed carefully to free a maximum of resources even when the system may have become unstable. In case of one or multiple errors, you should collect them in a DisposeException, continue with the execution, and throw it at the end of the method.

Note: The implementation must not return before the component is disposed. Any threads or asynchronous calls started must be completed before this method returns.

Throws:

DisposeException - if there was one or more errors while disposing the component.
