If you can't figure out a solution using existing components and layout
managers, write your own layout manager.
If you already know how to do the calculations for the sizes and the
absolute
positions, then writing your own layout manager is easy to do.
Well, I'm not sure that a full layout manager is called for, since it's
just for this one frame, with these specific components. I'll look into
it too, though. Thanks.
there is usually a multitude of ways to do things.
here is your layout , as i think you wanted it , including resize!!
the text area really does not look too good, full length of the window, so i
have adjusted it, also this code will resize smaller, than the previous
examples and retain some semblance of what is in it.
pls note when resizing, the areas will jump about and not maintain the ratio
, i don't know how you want it but you just need to play about with the
weights for each area
