About layouts

[Fernando Apesteguía <fernando apesteguia gmail com>]

Many, many thanks!!

Now I know what to do. I used GtkFixed because of my experience with Visual
Basic and some Java IDE's.

Again, thanks!!!

Best regards!!!!

Yeah, if you mean GtkFixed, abolish it.  It should only be used for really
special purposes, like maybe on a pocket computer with small fixed display
size etc.  Even then it is likely better to use other containers for windows
that are not heavily packed with many widgets.

A little unrelated, but at work I use Java and over time I developed this
policy: in GUI, prefer coding convenience over performance _nearly always_.
(An exception might be e.g. a text area that displays a quickly growing
log, like +30 lines per second, there you might need to pay special care to
performance.)

In your case, performance is less important yet, since you have the
dynamic/static layout alternative in the first place.  And I assume GtkFixed
is not quite convenient too work with either.  So, screw performance, there
are more important things at stake ;)

And actually, performance won't even suffer considerably.  So, switch to
dynamic layout, it's by far better in nearly all respects and only
marginally
worse in the others.
