nope, sorry if it was messed up but the xml was correct... there is an outer
canvas with a child vbox which, in turn, has 3 children: 2 vbox components and
a canvas - whose contents get included during runtime.
i'll try to explain my problem again :) let me clear up the mxml a little... ;)
<mx:Canvas id="outerCanvas">
<mx:VBox id="outermostVbox">
<mx:VBox id="vbox1"></mx:VBox>
<mx:Canvas id="innerCanvas"></mx:Canvas>
<mx:VBox id="vbox2"></mx:VBox>
</mx:VBox>
</mx:Canvas>
during runtime, this whole mxml is placed inside a draggable panel.
"innerCanvas" contains a graph/map representation that is created dynamically
during runtime. let's forget for the meantime about "vbox1" and "vbox2"
contents...
anyway, after "innerCanvas" is created during runtime, it is zoomed out. but,
after zoom out, i need it (the map) to center... or to focus at a certain point
(but that's another story). i accomplish this by targetting "outermostVbox"
using an <mx:Move>... so i did that. however, although the map *did* center,
the problem is that the scrollbars on the "outerCanvas" remained at 0 (and yes,
the scrollbars belonged to "outerCanvas" and not the draggable panel or the
other components). the consequence of this is that since the scrollbar is 0 and
the map centered, whatever fell to the *left* of the viewable area gets
clipped... that's why i need the scrollbar to move so that it would adjust
according to the position of the map... which it doesn't in my case.
so i debugged and i found out that the maxHorizontalScrollPosition is 0 so i
can't pretty much move the scrollbar... no matter where i looked, that position
is always 0... be it in the parent or the other children, etc. etc. so... the
part of the map outside of the viewable area is still unviewable...
i tried various means... from manipulating the size of the "innerCavas" so that
the "outerCanvas" would recognize the child canvas' dimensions (and hopefully
reassess that there IS a scrollbar so that the maxHorizontalScrollPosition
would have a value other than 0) to changing values of the scroll policies to
other things including the use of horizontalCenter and verticalCenter ^^;
however, it - the scrollbar - just doesn't want to move...
thanks so far for the replies :)

you are asking I'm afraid. Also the xml you supplied is not valid (jsut to be
picky). I assume you mean:
<canvas>
<vbox>
<vbox />
<canvas />
<vbox >
</vbox>
</canvas>
you coudl try horizontalCenter="0" and verticalCenter="0" on the inner canvas
to keep it centered. I'm not sure what you mean by the scrollbars and clipping.

hi, i'm relatively new to all this so
please bear with me... =)
i have something like this in my mxml file:
<canvas>
<vbox>
<vbox />
<canvas />
<vbox />
</vbox>
</canvas>
now, all of this gets stored inside a draggable panel during runtime.
also, during this time, the inner canvas gets zoomed out and should
center after the zoom... i accomplish this using <mx:Move>. however,
even if it does center, the content gets clipped and the horizontal
scrollbar still stays at 0 (most likely because the
maxHorizontalScrollPosition is also 0)... i tried various ways of
moving it already but it doesn't seem to want to since most of the
dimensions i need are 0 :(
if anyone can help, i would really appreciate it. thanks!
