[gtkmm] MDI on gtkmm

[Luis Pastor Vegas <lupv gmv es>]

Hi,

I'm trying to develop the MDI concept on gtkmm. We don't want to use the 
gnome libraries because we are evaluating only the gtkmm toolkit (we 
don't even use direct calls to gtk+ functions). Using Gtk::Layout as 
container it has been easy to emulate the MDI behaviour. The problem is 
that when a MDIchild contains a Gtk::ScrolledWindow, the scrollbars seem 
to be in a lower z-level than other widgets. So, when a MDIchild 
(mdiChild1) is over another MDIchild (mdiChild2), all the widgets 
comprised in mdiChild1 are over any widget comprised in mdiChild2, 
except the scrollbars, that are below and seem to disappear under mdiChild2.

Has anyone had a similar problem? What's wrong? What can I do?

Thank you very much,
Luis
