How to contribute actions to own SWT control? [message #261976]

Hi,

I have an SWT-control called 'Outline', which I want to use in my
plugin-application.

I made some wrapper called 'OutlineViewer' which extends Outline and
implements ISelectionProvider.

Then I want to add a popup-menu action which would popup when something
is selected in Outline.

Here is the View code:

public void createPartControl(final Composite aParent)
{
//--- cut ----
getSite().setSelectionProvider(m_OutlineViewer);
createContextMenu();
}
private void createContextMenu()
{
MenuManager menuMgr = new MenuManager();
menuMgr.setRemoveAllWhenShown(true);
menuMgr.addMenuListener(new IMenuListener()
{
public void menuAboutToShow(IMenuManager mgr)
{
fillContextMenu(mgr);
}
});
Menu menu = menuMgr.createContextMenu(m_OutlineViewer.getCanvas());

m_OutlineViewer.getCanvas().setMenu(menu);

// Register menu for extension.
getSite().registerContextMenu(menuMgr, m_OutlineViewer); }
private void fillContextMenu(IMenuManager mgr)
{
mgr.add(new GroupMarker(IWorkbenchActionConstants.MB_ADDITIONS));
}

OutlineViewer implements all neccesary methods, and they are even called
by the framework when i make a right-click on my viewer :-)
The problem is that menu manager doesnt get selection from the control,
though 'getSelection' method is called and always returns a consistent
object instance.

The action contribution is 100% correct: when i use the TableViewer
class instead of my viewer everything works fine...

What can be wrong?

Thank you,
Ilya

The soultion was to implement IStructuredSelection interface (but not
ISelection) for the selection object.
