As all panels are independent from each other, you'd need to register
for each panel's "changeValue" event. In case of a panel open, you need
to identify the panel, identify the associated widget in the stack (e.g.
by using userData with each panel), and then use the stack's
.setSelection() method to raise the corresponding widget.
But I would probably re-think using CollapsablePanel, as the stack has a
single selected item, whereas a group of CollapsablePanel's does not
support the idea of a single selection. What if a user opens three
different panels in a row, then closes the last again. What would that
mean for the stack? Or if no panel is open, which stack item would be
selected? Would you maintain an internal list of recently opened panels,
and a default stack item in case the list is empty?
