Before I start slogging through source code to decodce what each mgr

expand in size to fit the width/length of the text flows contained
therein, please tell!

Yes, I have. These examples, however, do not demonstrate the full depth
and breadth of the layouts available, nor do they replace good old
documentation. Since there is no online javadoc (that I have found so
far), I guess I just need to consult the source. If I do develop a
document, I will post it here.

Thanx for the pointers!

LayoutManagers in draw2d operate the same way as layout managers in AWT.
But, the set of available choices is different.

the getters don't set anything. The parent asks "try to fit within this
width", and the result says, "OK, I need this much width and height". Based
on that result, the flowpage is then given a new bounds via setBounds().
The final layout of the flowpage is based on its bounds, not on the hints.
most of time, its new bounds will match the hints passed in previously.

Omondo's EclipseUML tool - no documentation included for gef or draw2d!
Just went and grabbed them from the regular distribution. Thanx, Randy!
