Wondering if anyone knows how to get the difference between the scrollRect x
position relative to the components edges?
I am building a pancontrol, similar to the ones found Google Maps or Yahoo
Maps, for quick navigation.
In order to setup my pancontrol I need to find out the following given this
code:
<Application...
......
<mx:Canvas id="compHolder" width="100%" height="100%"
horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<components:myComp id="vis"
width="100%" height="100%"
horizontalScrollPolicy="off" verticalScrollPolicy="off"
backgroundAlpha="0"
scrollRect="{rec}"
cacheAsBitmap="true"
mouseUp="handleVisMouseUp()"
/>
</mx:Canvas>
I need to find the distance or gap between the vis.scrollRect x&y position
relative to the vis x&y position. My application width & height are 600 x 600.
Vis width and height are 3000 x 900 so they extend off screen. I am using the
scrollRect to limit what is viewable. But in order build my pancontrol I need
to find the diff between the X & Y of the scrollRect in relation to the X&Y of
the Vis. So how far off left, right, bottom, and top of the visible area does
Vis extend. I need those numbers in pixels.
TIA, J
