By size, Eric means its constraint's size, not its bounds. You should never
call setBounds unless you are writing a layout manager.
So:
Figure container = new Figure();
container.setLayoutManager(new XYLayoutManager());
Figure childWithLabels = new Figure();
container.add(childWithLabels, new Rectangle (x, y, -1, -1));

Sorry, I should've worded my reply better. Thanks, Randy.

Cannot seem to get it to work. What I have is a XYLayout (I want to pin the
X,Y coords but make the Figure grow to everything that is inside it). I add
the items to a figure inside a scroll pane by using:
getContentsFigure().add(item, new Rectangle(x, y, -1, -1));
The item is a Figure, with FlowLayout, and labels added one after another
using the standard add command.
The figure is only large enough to see the first label. How can I fix
this????
Thanks.

Have got it working now, the only problem now is now you cannot drag with
the mouse (ie set the bounds) of the figure when using XYLayout. Is there a
way around this.
Also, when drawing on the canvas like this, what is the best way to make the
ScollPane expand/contract the size of the Figure?

Got that working now! Just needed to change the Constraint information.
Sorry for your time.
