Question

I put some components to Group container, but I can move them outside container border and see them. How I can do the components could not be seen outside?
For example: 100*100 container, put into them simple button and setup (x,y) = (150, 150). So, button in container, but seen outside. I want to border of my container be a real border and hide outside components.

All you have to do, is set the Group’s clipAndEnableScrolling property to true (it is false by default).

<s:Group width="100" height="100" clipAndEnableScrolling="true">  
    <s:Image width="150" height="150" 
             source="@Embed(source='/gfx/myimage.jpg')"/> 
</s:Group>
