Hi,<br>Please "Reply all" when you answer, so that me, David and anybody interested could follow the *whole* thread!<br><br>Well, if you remove your text actor after creating it, you certainly won't have text displayed...<br>
For the first solution, you obviously have to memorize the previous added actor, then you can remove it when you want:<br>It seems that you dont use the Object Oriented capability of python, so you can forget the second solution.<br>

Hi,<br><br>If this part of code is inside your MoveMouse callback function, then you create a new actor as soon as you move, without hiding/removing the previous one.<br><br>2 solutions, if this is the problem:<br>- remove the actor before adding a new one <br>
- make Tactorx a member and instanciate it only once<br><br>HTH<br>Jerome<br><br><div class="gmail_quote">2009/11/18 RimAY <span dir="ltr"><<a href="mailto:rim.ayari@gmail.com" target="_blank">rim.ayari@gmail.com</a>></span><br>

Dear All ,<br>
Can someone give me an idea how can i change a text in the renderer with the<br>
mouse move event.<br>
I try with vtktextactor this is the part of my code:<br>
<br>
Tactorx = vtkTextActor()<br>
Tactorx.SetInput(cx)<br>
Tactorx.SetDisplayPosition(70,170)<br>
Tactorx.GetTextProperty().SetJustificationToCentered()<br>
renderer.AddActor(Tactorx)<br>
Tactorx.Modified()<br>
<br>
cx change its value with the mose move, i get the new value above the ancien<br>
one, the result is an illegible text :(<br>
<br>
Thanks a lot<br>
