The simplest way I can think of to do this is to add a custom
key-press-event handler to the TreeView. You can then pass on those
key combinations you want to trigger the search to the default
handler, and handle the rest as you desire.
something like:
def key_press(self, view, event):
if event.state & Gdk.ModifierType.SHIFT_MASK: return False # Shift
down, so propogate to the default handler
<do stuff>
return True # don't propogate this event further
And connect it up with a
view.connect('key-press-event', self.key_press)
when creating the view.
Hope that helps.
Note that, once the search entry is open, it's handling its own
key-press events. If you want it to ignore letters without shift there
as well, things get more complicated - I think the best way to achieve
that would be setting your own entry widget via
view.set_search_entry() .
