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.
text
the new text to insert
length
the length of the new text, in bytes, or -1 if new_text is nul-terminated
position
the position, in characters, at which to insert the new text. this is an in-out parameter. After the signal emission is finished, it should point after the newly inserted text.
