Re: vertical size of buttons

[Stephen Wilhelm <swilhelm theriver com>]

While the solution presented below is a correct answer to the problem,
it is generally not recommended that you use set_usize to set the size
of the widget.  Doing so prevents GTK from adjusting the size if
necessary (for example, a user might have a GTK style set the font to
really big because of eyesight problems, and such a change might prevent
the full text from appearing).  I would recommend one of two other
solutions.

First, you could use the border_width method to set a border around the
button, which will give you a small gap surrounding the entire widget.

Second, and almost certainly the better way to do this, put a vertical
packing box inside the horizontal packing box, and then insert the
button in the vertical packing box.  This way, the appearance of the
button is very flexible and easily adjusted.

Of course, if you know your users *very* well (such as you being the
only one) then any solution is acceptable.  But if not, I recommend that
you use an additional packing box (with the appropriate constraints so
that it looks good) and let GTK manage sizes for you.
