I'm using gtkmm to build a UI. The task I'm trying to accomplish is
constructing a radio button from an action that is already part of a
menu and a toolbar. I'd like the new button to proxy for the existing
action.
One likely candidate is Gtk::Action::create_tool_item(). Its
documentation states:
Deprecated: 3.10: Use a Gtk::ToolItem and associate it with a
Action using Gtk::Actionable::set_action_name() instead
So, I'd expect that ToolItem and by inheritance RadioToolButton would
implment this interface. In gtkmm-3.12 it does not and the stable
documentation reflects this as well.
However, the C library gtk-3.0 RadioToolButton does implement this
interface. So, my question is this.
*Should gtkmm Gtk::RadioToolButton implement Gtk::Actionable? Is the
absence of this int erface an oversight, or is there another way that
the features of Actionable are supported?*
The file toolbutton.hg contains this comment:
//TODO: Derive from (and implement) Actionable when we can break ABI.
The Actionable interface is new in gtk+ 3.4 and gtkmm 3.4. Gtk+ can add
interfaces without breaking ABI (application binary interface). Gtkmm can't.
The next ABI break will be when gtk+ 4.0 and gtkmm 4.0 are released. I
don't know when that will be.
There is a function, set_related_action() which associates the correct
icon for the radio button. It doesn't seem to put the button into the
group and it is also deprecated.
I tried this, and found that the button wasn't added to the
action_group and the icon didn't appear.
auto tool = Gtk::manage (new Gtk::RadioToolButton ());
gtk_actionable_set_action_name (GTK_ACTIONABLE (tool->gobj
()), "sample-radio-action");
What am I missing?
