Hi,
probably a pretty dumb question:
Is there a way to constrain the maximum size of a user area?
I know, minimum size is no problem. Now, I'd like to constrain the maximum height or width dynamically. But when Sized() is called, there's no way to report back, that one is not able to handle a size request of the given size and would like to keep (at least) one direction smaller than requested?
Basically I'd like to constrain the size to a more or less rectangular shape.
Would I be better off by rather handling the "sized" message?
Or is this simply impossible?

Regards,
Andreas

Think of a GeUserArea as a virtual infinite plane (but with a boundary at 0,0 top/left) that is windowed into using a particular size view area that is displayed - you may not have control over the view area size if, say, you have the BFH_SCALEFIT|BFV_SCALEFIT flags set.  You can limit the windowed view area but not the extent of the virtual space.  You may be able to place restraints on that windowed area using a ScrollGroup with SetVisibleArea()/GetVisibleArea().  In other words, you control the size of the GeUserArea with a ScrollGroup.  At least, that is how I think it may work.
