Hi all,
I have a perspective containing a top view and a folder with four stacked views:
layout.addView(WorkitemView.ID, IPageLayout.LEFT, 1.0f, IPageLayout.ID_EDITOR_AREA);
IFolderLayout folder = layout.createFolder("folder", IPageLayout.BOTTOM, 0.7f, WorkitemView.ID);
folder.addView(VariablesView.ID);
folder.addView(PackagesView.ID);
folder.addView(AttachmentsView.ID);
folder.addView(ErrorView.ID);
The views in the folder all need to update when a selection is made in the top view. This is accomplished by adding a selection listener. However, only the view that is actually shown reacts on the selection. When I select another view, it is still empty.
The code that adds the selection listener is placed in the view's init() method and apparently this is only called for the first view in the folder when the perspective is loaded.
Is there a way to switch off this "lazy loading" so that all views are created (and their init() method called) when the perspective is created?
Thanks in advance for any help,
Arjan

No.

Why don't you simply fetch the current selection once the other view is
initialized?

Just a quick follow-up:
I have succeeded in getting the behavior I wanted. To accomplish this, I first had to add a perspective listener. This was done in the actual PerspectiveFactory class.
public class WorkflowPerspective implements IPerspectiveFactory {
public static final String ID = "lime.workflow.perspective";
@Override
public void createInitialLayout(IPageLayout layout) {
layout.setEditorAreaVisible(false);
layout.setFixed(false);
layout.addView(WorkitemView.ID, IPageLayout.LEFT, 1.0f, IPageLayout.ID_EDITOR_AREA);
IFolderLayout folder = layout.createFolder("folder", IPageLayout.BOTTOM, 0.7f, WorkitemView.ID);
folder.addView(VariablesView.ID);
folder.addView(PackagesView.ID);
folder.addView(AttachmentsView.ID);
folder.addView(ErrorView.ID);
IWorkbenchWindow workbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
workbenchWindow.addPerspectiveListener(new MyPerspectiveAdapter());
}
}
Next I implemented the listener by subclassing PerspectiveAdapter.
public class MyPerspectiveAdapter extends PerspectiveAdapter {
@Override
public void perspectiveActivated(IWorkbenchPage page, IPerspectiveDescriptor perspective) {
IViewReference[] references = page.getViewReferences();
for (IViewReference reference : references) {
try {
page.showView(reference.getId(), null, IWorkbenchPage.VIEW_CREATE);
} catch (PartInitException e) {
throw new LimeException(e);
}
}
}
}
Thanks for all the help!
