Re: notify components when their global coordinates are changing

[Cristina Constantinescu]

Example:
<s:Group id="canvas" width="100" height="100">
        <s:layout>
            <s:BasicLayout />
        </s:layout>
        <s:Group id="component" x="10" y="10" width="20" height="20">
            <s:layout>
                <s:BasicLayout />
            </s:layout>
            <s:VGroup id="child1" x="0" y="0" width="10" height="10"/>
            <s:VGroup id="child2" x="10" y="5" width="10" height="10"/>
        </s:Group>

        <s:Image id="image" />
        ...
 </s:Group>

What I need: when "child1" changes its coordinates (relative to 
"canvas"), the "image"coordinates  are modified in some way.
So, this happens when:
1. "component" changes dimensions/coordinates
2. children changes their order in parent (e.g. "child2" becomes first 
element)

Can "child1" be notified about these type of changes?

Hello,

Is there a way to notify children when parent changes its 
dimensions/coordinates?

For the moment, my solution is to add a resize event listener on parent.
When the event is dispatched, the child gets its global coordinates 
and uses them to position some additional components.

Is there another approach for this?  (like each child to be notified 
somehow when their global coordinates are changing)

Thanks,
Cristina
