In your example, your outer container does not have any width set and it
doesn't have a maxWidth set, so, all internal controls can expand it to
accommodate. And since the label needs more room to show all content the
container is more then happy to expend to let it all show. If you don't want
that to happen then you need to set a maxWidth on the container or the
label. So, if you are relying on your designer to make the page look
correct, then your designer need to know all the rules or you are going to
end up with this type of thing more often. In general, the web is fluid
unless you tell it not to be. And since you didn't tell it to stop
expanding, it just kept going. Your example does exactly what I would expect
it to do, and there is no reason to expect it to do any different.
"For example, if you add a TextField in exactly the same way, it does not
cause the composite to grow." - this is not correct. If you add a TextField
to the container, and it has a width of 300 pixels, your container
absolutely will expand to fit because there is nothing telling it not to,
does that make sense? You have placed no restrictions on the container. You
simply created it and asked it to hold a few controls, and it did.
