Hi,
I constantly find myself writing this code:
if (selection instanceof IStructuredSelection) {
if (((IStructuredSelection)
selection).getFirstElement().getClass().equals(clazz)) {
return ((IStructuredSelection) selection).getFirstElement();
}
}
Is there a utility class available for ISelection and subordinates?
Thanks in advance and best regards,
Wim Jongman

Hi Boris,
Thanks for your help. I already started a SelectionUtil class and if i'm
happy with it I wil do as you suggested. I'm curious about the e4 solution.
Have not seen e4 yet, but if I can find it I will give it a spin today.

Hi Wim,
The solution for this in e4 is maybe not that easy to find... have a look at
the class "ExifTable" which implements the view displaying Exif data for
images. The idea is that the code that unwraps a selection should be outside
of the views, all you do is implement a method setInput(DomainObject o),
which will be called when there is an "input" of that type available for the
view.
