My bad. I should have tried it before giving you an answer.
This works nicely:
<mx:TabNavigator ... />
<mx:Canvas ... />
<mx:Grid ... />
<mx:GridItem>
<mx:TextInput rollOver="showInfo(event)"
rollOut="hideInfo()" />
<mx:GridItem>
</mx:Grid>
</mx:Canvas>
</mx:TabNavigator>
import mx.managers.PopUpManager;
private function showInfo( event:flash.events.MouseEvent ) :
void
var p:Point = new Point(event.target.x, event.target.y);
var pt:DisplayObject = DisplayObject(event.target);
p = pt.localToGlobal(p);
tip = PopUpManager.createPopUp( this, <<your class
here>>, false ) as <<your class here>>;
tip.move( p.x+pt.width+5, p.y );
When the mouse rolls over the TextInput (or whatever control
you want), showInfo is called. The showInfo function converts the
position of the TextInput (that's event.target) to global
coordinates. Then the pop-up is created and moved into position,
just to the right of the TextInput.
I have working code if you want it.
