I have created a RCP application and have created 2 perspectives 'base.perspective.per1' and 'base.perspective.per2' in the plugin.xml and have created corresponding classes that implements the IPerspectiveFactory.
When I run the application I can select between the two perspectives just fine (like I can switch between multiple perspectives in eclipse).
Now to my problem. When I start my application I would like to filter the entries in the perspectives list (based on some condition) so each time the application start the perspectives that can be enabled might be different.
Here is what I do in the ApplicationWorkbenchWindowAdvisor:
@Override
public void preWindowOpen() {
final IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
configurer.setInitialSize(new Point(1200, 1000));
configurer.setShowCoolBar(true);
configurer.setShowStatusLine(true);
configurer.setShowProgressIndicator(true);
configurer.setShowMenuBar(true);
configurer.setShowPerspectiveBar(true);
IPerspectiveRegistry perspectiveRegistry = PlatformUI.getWorkbench()
.getPerspectiveRegistry();
IPerspectiveDescriptor[] perspectives = perspectiveRegistry
.getPerspectives();
for (IPerspectiveDescriptor iPerspectiveDescriptor : perspectives) {
if (iPerspectiveDescriptor.getId().equals(
"base.perspective.per1")) {
perspectiveRegistry.deletePerspective(iPerspectiveDescriptor);
}
}
}
The problem with using the deletePerspective method is:
"Deletes a perspective. Has no effect if the perspective is defined in an extension."
So since my perspectives are defined in the plugin.xml this does not work.
Is it only possible to dynamically modify the perspectives list for non-extension perspectives, or is there another approach to what I need?
