[Glade-users] glade-3 3.6.7 requires property orientation vertical for GtkVBox

[stebbins at jetheaddev.com (John Stebbins)]

Bug or feature?

If a GtkVBox does not have:
<property name="orientation">vertical</property>
then glade-3 shows the VBox as if it were an HBox.

I haven't tested whether this is also the case with current git head of
glade.  git head requires gtk 2.19 which I don't have.

libgtk/gtkbuilder does not require this property in order to correctly
layout a VBox.
