Thanks Doug
I took the easier route and simply changed how I was stacking
things. :-)

sorry, first part of my message wasn't really applicable, since you
were trying to use the inner canvas for clipping, not the outer, but
the code should work OK.

Guy, your inner cnavas takes up 100% width, so as far as yourouter
canvas knows, it doesn't need to clip the children. clipContent
doesn't force clipping, it simply turns it on if needed, and the
Canvas determines if it needs clipping based on whether any of the
children are placed outside of the visible bounds.
I usually just add a dummy UIComponent object and place it at -1,-1
in the canvas. So try this:
<mx:Canvas clipContent="true" id="containerLayer" bottom="0"
left="350" top="0" right="0" horizontalScrollPolicy="off"
verticalScrollPolicy="off" >
<mx:Canvas id="dynamicLayer" clipContent="true" width="100%"
height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:UIComponent x="-'1" y="-1" />
</mx:Canvas>
</mx:Canvas>

Does clipContent clip the Graphics object or just DisplayObject
children?

Hi Mike
I know for sure that the graphics are being drawn outside the
enclosing canvas, because the child canvas is drawing x values < 0
and these aren't being clipped but are visible outside the map area.

Hi Guy,
Are you actually measuring the graphics that you draw (in a sub
component, the child of the canvas)?
Is there a possibility that canvas is not knowing if the graphics
are extending passed what it THINKS is the measured width and height?

I have a problem in that clipContent seems to intermittently not clip
the content in a layer as I imagine it should.
The graphics in the layer are drawn using the graphics class and the
layer is inside another Canvas, eg
<mx:Canvas clipContent="true" id="containerLayer" bottom="0"
left="350" top="0" right="0" horizontalScrollPolicy="off"
verticalScrollPolicy="off" >
<mx:Canvas id="dynamicLayer" clipContent="true" width="100%"
height="100%" horizontalScrollPolicy="off"
verticalScrollPolicy="off" />
</mx:Canvas>
MOST of the time the content drawn in the nested canvas is clipped
correctly, but sometimes it spills over the content to the left of
the
containing canvas.
Anyone got any ideas as to why this happens and how to prevent it?
TIA
