gtk:sorter-changed (sorter change)

sorter -- a gtk:sorter object
change -- a gtk:sorter-change value

Emits the "changed" signal to notify all users of the sorter that it has changed. Users of the sorter should then update the sort order via the gtk:sorter-compare function.

Depending on the change parameter, it may be possible to update the sort order without a full resorting. Refer to the gtk:sorter-change documentation for details.

This function is intended for implementors of gtk:sorter subclasses and should not be called from other functions.
