Create a dialog with Glade

[gikotim bluemail ch]

I've created a Gnome(-perl) application with Glade-GUI-builder. So far no
problem. Now I want to pop up a dialog. I can design a dialog-box with Glade
and can specify "dialog" as type. So far no problem. But when I now let the
code be generated, it will create a toplevel class with Gtk->Main and all
that stuff. Is there no way to create dialogs (or similar things) within
an existing application and call them afterwards with a $dlg->new... ??
