I am trying to use Gio::Settings to get notified about changes to a
particular property value, doing something like
class X {
public:
X();
private:
Glib::RefPtr<Gio::Settings> settings;
void handler();
}
X::X()
{
settings =
Gio::Settings::create("org.cinnamon.desktop.interface");
settings->connect_property_changed("text-scaling-factor",
sigc::mem_fun(*this, &X::handler));
}
void X::handler()
{
// do something with changed setting.
}
However, the X::handler() is never called when I change the setting.
I did check that if I monitor the setting with
gsettings monitor org.cinnamon.desktop.interface text-scaling-factor
and make a change using e.g. dconf-editor I can see that the value
changes.
Any ideas on what I'm doing wrong? Or is there someone with a simple
Gio::Settings example able to help me out? (Would, incidentally, make a
good addition to the gtkmm book.) Thanks!
Cheers,
Kasper
