Thread Subject: Closing GUI windows

I'd like to make sure all GUI windows are closed when I close
the main GUI window. Unfortunately, if I call

delete(sub_gui)

when the sub_gui window isn't open, it briefly becomes visible
before disappearing again. I tried to find a way to tell if it
is open so that I don't delete it unless it is, but any reference
to sub_gui, as in ~isempty(sub_gui), causes the flickering effect.

What is the approved way of ensuring that all secondary figures
are closed when the main window is closed?

Cheers,
Francis

I found

delete(0,get(0,'Children'))

and

close all

The latter is preferable for me, because it executes the figures'
CloseRequestFcn, which I use to save the windows' positions on
screen in an .INI file (using Iroln's excellent IniConfig object).
