In the specific case of Client Side Decorations (CSD), like in Gnome,
applications can use GtkHeaderBar, where you can set a tooltip.

In Evince we do that for a similar use case you mention. A GtkHeaderBar
can have a title and subtitle. In the subtitle we present the filename
(basename), but you can get the full path through the tooltip.

Re: State actions and Glade

"I am not sure what you mean"

I don't have a good answer for this. I see that GtkRadioToolButton is in the 
list of Known Implementations for GtkActionable but doesn't use the GAction 
interface directly.

https://developer.gnome.org/gtk3/stable/GtkActionable.html#gtk-actionable-set-detailed-action-name

It looks like this allows you to set up your action groups and callbacks with 
GIO but I don't have experience with it. Maybe someone has an example of 
setting up widgets to use action callbacks?

Re: State actions and Glade

Hi,

Thank you for your reply. I am not sure what you mean by "GtkToolbar
doesn't implement the GAction interface". In Glade, I can define the
specify the "Action Name" for each individual widget in the Toolbar. Those
action names get automatically linked to the actions that I've defined in
the my GActionEntry array. The only thing that does not work are the Radio
button actions.

Thank you,
Mitko
