Hi,
All the views in my RCP application publish selection events using
getSite().setSelectionProvider(viewer);
Only certain objects in certain views should show properties. The
properties view will render a selected object if the selected object
implements IAdaptable that returns an IPropertySource. If the selected
view does not implement IAdaptable and/or return an IPropertySource,
then the Properties view shows blank.
So my question is: How do I make the properties view render the
properties of only those objects that implement IAdaptable which return
an IPropertySource ?

Hi,
i lately had the same Problem. What i basically did to solved it, was to
override the Default Properties view and write my own selection Changed
listener which in case there is no PropertySource available for the
current selection uses the last shown selection. I did this like this:
public class MyPropertySheet extends PropertySheet
{
private static ISelection lastSelection = null;
@Override
public void selectionChanged(IWorkbenchPart part, ISelection selection)
{
/* First we check if the current selection Provides an
* IPropertySource if so we provide it as current selection
*/
if (selection instanceof IStructuredSelection){
IStructuredSelection sel = (IStructuredSelection)selection;
if (sel.getFirstElement() instanceof IAdaptable)
{
IAdaptable adapter = (IAdaptable)sel.getFirstElement();
if (adapter.getAdapter(IPropertySource.class) != null)
{
super.selectionChanged(part, selection);
lastSelection = selection;
return;
}
}
}
super.selectionChanged(part, lastSelection);
}
}
For this new View i used the same id used for the original Property
Sheet view. By doing this the original view is replaced by my new view.
