I create object GtkTreeView with the type of storage GtkTreeStore.
Then connect to GtkTreeView signal handler button-press-event.
In this event handler is called, but there is no selection line.
If I attach a handler to the signal button-release-event, then the
handler is called, is an selection of the line, but fails to deploy a
substring by pressing [+]
No errors in stderr.
The letter attached pieces of source code.
