By using += with the text property of the buffer you are re-writing the wholebuffer on each change. You 
should probably be looking at one of the insertfunctions of Gtk.TextBuffer.
I doubt Vala is removing trailing newlines unless you are telling your program to, even if unintentionally! 
Your Vala program is using library functions so lookcarefully at these library functions' documentation and 
what they are returning.

You would want a 4 column grid and to make the width of the view3 and the width of the scale 1. A nice 
example (Python):http://python-gtk-3-tutorial.readthedocs.io/en/latest/layout.html#id1
