[Glade-users] Can't add a headerbar to an ApplicationWindow

[William Kevin Manire]

Dear Glade Users,

I've pulled the latest version of glade (3.20) from the git repository 
and have it built and running in Gnome 3.20 on Ubuntu 16.04.

I specifically upgraded because of the GtkHeaderBar support, but I can't 
seem to figure out how to replace the title bar of an application window 
with the header bar. I've clicked the "Client side window decorations" 
checkbox but when I try to add a headerbar it just goes into the body of 
the window. Instead of replacing the title bar I get the standard title 
bar and then the headerbar stacked underneath it.

How is this supposed to work?

Regards,
