[luau] java on linux question - sorry, source inserted

> Uhm, for those people who program in Java on Linux, 

I'm not really qualified to answer, because I haven't used Java in
a while and I haven't ever used  a GridBagLayout,
but I'm going to guess, and it probably won't be much help you.

All of my speculation is based on guessed semantics from the names
of the classes.

I'm guessing the fill member of the constraints object specifies whether 
the given control should
grow to fill any surplus it has in its cell(s).  I'm guessing that the 
BOTH constant means the
control should grow both horizontally and vertically.  I'm guessing 
gridwidth is the number of cells
the given control is allocated horizontally (something like colspan in 
html).  Are my assumptions
correct?

I think that the fact the buttons are different widths are a symptom of 
the problem, not the cause.
The grid columns themselves are different widths, and the buttons are 
configured to fill the entire
width of their respective columns.  I think if you set the fill member 
to 0 or NEITHER or NONE or
whatever the constant is called, then the buttons would be the same 
width, but the spacing
would look weird.  Am I right?

Now here is my completely uniformed guess at what might be going wrong:

I think your problem might actually be the labels.  They are probably 
going to try to prevent
themselves from wrapping or at least wrapping on non-whitespace as much 
as they are able.
So the columns with labels are probably as wide as the labels, which are 
probably wider than
the other columns, becuase the other columns contain controls that 
handle small space better
(e.g. the text controls scroll and clip, the buttons shrink, etc..).

If what i'm saying is right, then the first and fourth columns probably 
have the widest buttons.

Again, though, I want to make it clear to you that I'm just guessing and 
have no idea if that is
actually the problem.  I don't use Java very much.

Another possible guess: it wants a new contraints object for every add 
call, and by passing
the same reference around you are confusing it?  I haven't looked at the 
documentation, so
I don't know what it expects.

One general note:

I think it would better, if you moved this down a line and changed it
to g.gridx++....

...then this line wouldn't be needed, yes?
