How to update a "child" figure?

I have a manually generated gui which consists of a parent figure with a number of child figures laid out on uipanels.
If I click something in one of the child figure I can cause something to happen in the parent figure using a figure handle passed to the child figure as an argument when I call the function that creates it.
Is there are way of triggering in the other direction, i.e. once the child has been created, if I click something in the parent figure how do I cause something to happen in the child figure?

Save the handle to the child figure in appdata and set it as necessary:
setappdata(hParent,'hChild1',hChild);
On click:
hChild = getappdata(hParent,'hChild');
set(hChild,...)

Sure you can save the figure handle in appdata, that's what my above setappdata command did.
doc setappdata/doc getappdata for more info
