Unless I am missing something you can still draw twice. Create the
text, draw, create the box and add it to the model containing the text
and draw again. They will in effect be drawn at the same time since the
redraw would be so quick.

Another option would be to create a "boxed text" object which is a
subclass of IDLgrModel. Override the superclass draw method such that
if it is the first time being called (or text parameters have changed)
you modify your box dimensions. This would be the way to go if you were
going to use this often.

This works too :)
