This function should be called when the top-level window
which contains the search entry received a key event. If
the entry is part of a gtk.SearchBar, it is preferable
to call SearchBar.handleEvent instead, which will
reveal the entry in addition to passing the event to this
function.
If the key event is handled by the search entry and starts
or continues a search, GDK_EVENT_STOP will be returned.
The caller should ensure that the entry is shown in this
case, and not propagate the event further.
