How would I do this with GridLayout,

Shrugs: provide some code and perhaps we'll see.

since I'm using GridLayout. Here
are the details.

In a frame, I first add a push button at the top. Below the button I
add two tables, side by side.

The frame already resizes vertically to any length which is good.

But, I want the frame to not resize horizontally beyond a certain
hardcoded limit. I.E.: I want the frame to resize horizontally, but
attempts to resize beyond a certain limit are prevented. So, if a user
were to try to resize horizontally beyond the limit then the resulting
horizontal width of the frame would be the limit.

     Perhaps it's time to ask a question: Why do you think it's a
good idea to prevent the user from arranging his own screen as
he pleases? Does your program understand the user's needs and
desires better than he himself does?

I've used such a program.

     Did you enjoy it? ;-)

     That is: Did you consider it a benefit, a point in the
program's favor, when the program's window resisted all your
efforts to make it larger? Did this behavior improve your
experience of using the program?

Oh. I was responding to your comment concerning the program(mer)
who perhaps understands my needs and desires better than I do.
Many programmers provide sensible default behavior for users,
like me, who might not be familiar with the program or even
the subject matter. I don't recall seeing a GUI behavior such as describes, but maybe the subject matter warrants such.

     Sorry for the misunderstanding.

     It's certainly possible that Clusardi's situation does in fact
make such Thou Shalt Not behavior desirable, perhaps useful or even
essential. That's why I raised the question: Not to deny that there
could be a reason, but to ensure that the reason had actually been
examined and evaluated.

     I guess there are three questions, really:

     1) Is the size restriction really desirable?

     2) If (1), then must it be applied to the entire frame
        rather than to a sub-component like an interior JPanel?

     3) If (2), then Clusardi's original question: "How?"

Maybe if the reasons for "Yes" answers to (1) and (2) were
made public, somebody might have a better idea how to answer
(3) -- or how to do something different but satisfactory.
