Both the scalar bar actor and the balloon are actor2D's and <br>have no depth information. ie, they are rendered on the <br>overlay plane. The only thing controlling who is on top is the<br>order in which the props are added to the renderer.<br>
<br>Two solutions.<br><br>1. Bad one. Enable the balloon widget after the scalar bar<br><br>2. Good one. Add the two to different layers. Props in different<br>layers are composited one after another.<br><br><div class="gmail_quote">

Hi All,<br>
I've attached a vtkBalloonWidget to vtkScalarBarActor and it appears when I<br>
hover over the scalar bar BUT it renders behind the scalar bar (see<br>
attached). Is there a way to specify the ordering so taht the balloon<br>
widget renders on top (last).<br>
