2.4 Draw2D View
The above example diagram can also be displayed in a view that is part of an Eclipse RCP application (see Chapter 7 in the Eclipse Plug-ins book for more about views). Start by adding the following extension to the plugin.xml:
<extension point="org.eclipse.ui.views">
<category
id="com.qualityeclipse.gef"
name="GEF Book">
</category>
<view
category="com.qualityeclipse.gef"
class="com.qualityeclipse.genealogy.view.GenealogyView"
id="com.qualityeclipse.genealogy.view"
name="Genealogy"
restorable="true">
</view>
</extension>
Now modify the GenealogyView class to be a subclass of org.eclipse.ui.part.ViewPart, and add the following methods:
package com.qualityeclipse.genealogy.view;
... existing imports ...
import org.eclipse.ui.part.ViewPart;
public class GenealogyView extends ViewPart
{
public void createPartControl(Composite parent) {
createDiagram(parent);
}
public void setFocus() {
}
... existing methods ...
}
When you launch the runtime workbench and open the Genealogy view, you'll see something like this (see Figure 2–6).
