Re: [flexcoders] clipContent doesn't always clip content
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?

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.

Re: [flexcoders] clipContent doesn't always clip content
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.

Re: [flexcoders] clipContent doesn't always clip content
Does clipContent clip the Graphics object or just DisplayObject children?

Re: [flexcoders] clipContent doesn't always clip content
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 On Fri, Sep 5, 2008 at 7:40 AM, Danny Gold [EMAIL PROTECTED] wrote: Does clipContent clip the Graphics object or just DisplayObject children?

Re: [flexcoders] clipContent doesn't always clip content
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.

Thanks Doug I took the easier route and simply changed how I was stacking things. :-) Guy On 06/09/2008, at 1:52 AM, Doug McCune wrote: 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.
