How to select a treeview node like a click of mouse to update properties view

问题

I have a custom outline in my Eclipse plug-in, implemented using class TreeViewer and I created this outline using this code:

public class MyOutlinePage extends ContentOutlinePage
(...)
            Object[] data = (...)
            TreeViewer treeViewer = getTreeViewer();
            treeViewer.setInput(data);

After set input I need to select one specific element in outline. For example, I need to select the element data[2] in the outline.

Im trying to use this code to select the emelent of outline:

treeViewer.setSelection(new StructuredSelection(data[2]));

If I select the outline item using mouse, the outline was selected and the "Properties Views" was updated. The outline item is selected as shown:

But If I select the outline item using the method setSelection the "Properties Views" was NOT updated and the outline item is selected as shown:

I need to select outline item using code and this selection must update the "Properties View" like the click of mouse does.

回答1:

The gray highlight shows that the outline view is not the active part. The Properties view always shows values from the active part.

You can activate the Outline view with:

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();

page.showView(IPageLayout.ID_OUTLINE, null, IWorkbenchPage.VIEW_ACTIVATE);

but note that this will move focus away from whatever part is currently active.
