Removing components from view? [message #120618]

I would like to alter the my view dynamically based on the state of the
user (authenticated or not). If they are not authenticated, I would like
the view to display an informational message. If they are authenticated,
I would like the view to dynamically update by displaying the components
available to the user (Example: add some buttons to the composite).

I know I could set the label as visible(false), but that would leave a gap
at the top of my view pane. I would prefer to remove the component.

Does anyone know if this is possible?

Actually, I think I was thinking more along the lines of the Page views
which I see is how Eclipse handles the Outline view. Thanks.

StackLayout lets you switch which widget displays in the outer
Composite. You just set the top widget into the StackLayout instance and
then redo the layout() on the outer Composite. This will then hide the
current top widget and show the one you just set.

But, that's not fair. You said you wanted to *remove* the widget, not hide
it behind another :-)
