Interface Page

All Known Implementing Classes:

MainPage

public interface Page

A server side page

A page gets created by the page provider. The createContent(Composite) must only be called once. Resources that be page need must not be created before calling this method. If the method is never called the page instance is simply subject to garbage collections. Once the page content is created the page can attach itself to the parent composite using Widget.addDisposeListener(org.eclipse.swt.events.DisposeListener) to get notified about disposal.

The request close method must also be allowed to be called if the createContent(Composite) was not called. In which case it should simply return true. The requestClose() method may also be called multiple times, but only as long as the parent composite is not disposed.

0.2.0
