Emitted when text is inserted into the widget by the user.
The default handler for this signal will normally be responsible
for inserting the text, so by connecting to this signal and then
stopping the signal with g_signal_stop_emission(), it is possible
to modify the inserted text, or prevent it from being inserted entirely.
