gtk:filter-changed (filter change)

filter -- a gtk:filter object
change -- a gtk:filter-change value

Emits the "changed" signal to notify all users of the filter that the filter changed. Users of the filter should then check items again via the gtk:filter-match function. Depending on the change parameter, not all items need to be changed, but only some. Refer to the gtk:filter-change documentation for details. This function is intended for implementors of gtk:filter subclasses and should not be called from other functions.
