Subject: Re: FXRuby : Setting Default Height/Width in an FXList

Gah.... this [small] problem is really starting to
irritate me.  Thank you so much for your help Lyle...
I wouldv'e given up by now if you weren't here ;)

Here's my latest issue:

I'm attempting to wipe everything from one area and
replace it with some other widgets.  I have two
strategies.

(1) delete and recreate the parent
newParent = FXVerticalFrame.new(parent.parent, ...)
parent.destroy
parent = newParent
parent.create

this is sloppy, but I figured it'd work. 
Unfortunately, the parent disappears, but the new one
doesn't take it's place (although it DOES exist out
there)

(2) delete all the child widgets of parent
0.upto(parent.numChildren-1) do |childNum|
  parent.childAt(childNum).destroy
end

Now, this ALMOST works... the problem here is that the
parent widget still counts the old children towards
the total child height (which seems like a bug to me)
and places the next new widget urther down.  And
parent.setHeight(0) doesn't seem to have an effect.

Whew... have at it!
