Re: How center a small button horizontally like in this picture....

Debby,

I think the problem is that you have a "\n" at the end of your label:

>       buffer = g_strdup_printf ("variable %d\n", j);

Thus, in your attempts to align the label, you're attempting to align two
lines of text instead of one.  

I modified your code such that there was no "\n" and there was no 
alignment object (see below) and it seems to work okay here.  Please let me
know if it doesn't work for you.
