The instance created by glade is nothing more mysterious than an
instance created by yourself.

I was adding some misc widgets to a Glade-created container. There was
no problem, expect i always forget to do a gtk_widget_show_all for the
child widget to be added.

My suggestion for you on this problem is to make a window by yourself
with a HBox in it, and see if your newly added widget shows up with your
code.

Do a g_assert(((GtkWidget*)lab)->parent == hbox)) to see if the widget
is added to the parent before you show_all on the hbox.

Best,
