When accel.group is being activated in response to a call to
gtkAccelGroupsActivate, closure will be invoked if the accel.key and
accel.mods from gtkAccelGroupsActivate match the key and modifiers
for the path.gtkAccelGroupConnectByPath(object, accel.path, closure)objectaccel.pathclosureclosure is that of GtkAccelGroupActivate.
Note that accel.path string will be stored in a GQuark. Therefore, if you
pass a static string, you can save some memory by interning it first with
gInternStaticString().
