RE: [flexcoders] scrollRect ???
I'm pretty sure scrollrects are always positioned at 0,0. It essentially
creates a mask of a certain size, positions it at 0,0, then only shows the
pixels that would otherwise be displayed at x,y at 0,0

Subject: [flexcoders] scrollRect ???
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 xy position
relative to the vis xy 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 XY 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

[flexcoders] scrollRect width and height - flexaustin
I have tried increasing the width/ height of the scrollRect once its been set, say your swf scales ot the window size, but nothing will increase its width or height. So, instead of increaseing and decreasing the width and height of the scrollRect when the stage is resized I just create and assign a new rectangle to the components scrollRect property setting its width and height to the new stage size. Is there a better solution? As trying component.scrollRect.width = newSize does nothing to the scrollRect. Any better solutions?
RE: [flexcoders] scrollRect width and height - flexaustin
Many complex properties in Flash and Flex (arrays, rectangles, etc) need to be fully re-assigned as there is no way to watch each property for changes.

[flexcoders] scrollRect confusion
hi.
i'm loading an image at runtime into an image component. i want the component
to have horizontal and vertical scrollbars. the image is 300x300 and the image
i'm loading in is 500x500. i thought i could simply define a rectangle for the
'scrollRect' property of the image but it doesn't appear to be working.
am i correct in thinking that i can do this?
here's the code (init() is called on creationComplete):
[Bindable]
private var viewPort:Rectangle;
private function init():void{
viewPort = new Rectangle(0, 0, 500, 500);
}
mx:Image
width=300
height=300
showBusyCursor=true
source={myRuntimeImage}
scrollRect={viewPort}/
any tips are appreciated. - thank you. -- matt.
Re: [flexcoders] scrollRect confusion
scrollRect just provides clipping, it does not add scrollbars, etc. For
that, I'd recommend just putting your image component inside of a Canvas
component.

Re: [flexcoders] scrollRect confusion
that works well. and here i was thinking that i might have to create a
composite component with an HScrollBar and VScrollBar.
thank you. -- matt.
