You should have gotten an error message printed when you ran your
program that GtkTextView has no "activate" signal.

Pressing enter in GtkTextView starts a new line, it's a multi-line
control. The single-line control with an activate signal is GtkEntry.

This is wrong; textLength as accepted by vte_terminal_feed() should be
in bytes, not characters.

gtk_text_buffer_get_bounds()

Always read your error messages. ;-)
