Re: GtkTextView - The “extend-selection” signal

Well I did it, thank you very much!

void
cb_gtk_handle_selection (GtkTextBuffer *buffer)
{
    GtkTextIter start;
    GtkTextIter end;

    gtk_text_buffer_get_selection_bounds (buffer, &start, &end);
}

int main ()
{
    ...
    g_signal_connect_swapped (buffer, "notify::has-selection",
                                                  G_CALLBACK
(cb_handle_selection_mouse), buffer);
    ...
}
