<br>
Thank you for your suggestions.<br>
<br>
By moving, I meant an interaction with a mouse.<br>
Indeed, I have no interaction style defined explicitly, but it seems that Python interface has some default one set up, because I was able to run this:<br>
<br>
lines_actor.PickableOff()<br>
print lines_actor.GetPickable()<br>
lines_actor.PickableOn()<br>
print lines_actor.GetPickable()<br>
lines_actor.SetPickable(0)<br>
print lines_actor.GetPickable()<br>
<br>
which produced:<br>
0<br>
1<br>
0<br>
<br>
(I apologize if this is something obvious for you, I just started experimenting with VTK)<br>
So, vtkActor() has an interaction style by default, thus I was able to call PickableOff() on it.<br>
However it does not work, while I was able to pick and move around (rotate) lines_actor with the mouse.<br>
<br>
I had the same issue with lines_actor.DragableOff().<br>
<br>
What is surprising, lines_actor.VisibilityOff() works fine! (lines_actor was not visible on the scene)<br>
<br>
Do you possibly have ideas what can interfere with the PickableOff() ??<br>
<br>
Thanks for any suggestions,<br><font color="#888888">

Hi Piotr,<br>
<br>
Perhaps you could clarify what you mean by moving an actor. It doesn't<br>
sound like you have an interactor style that is manipulating the<br>
actors by picking with the mouse. If you did, however, you could call<br>
PickableOff() on the actor, which will prevent you from picking it and<br>
thereby prevent movement of the actor.<br>
<br>
How exactly are you moving the actors now?<br>
<br>

Hi,<br>
<br>
I want to set an actor to be movable or non-movable, depending on settings<br>
which I control through PyQT GUI.<br>
In other words, having a few actors on the scene I want to set checkboxes in<br>
my GUI that would freeze a given actor, and the rest of them to react as<br>
usual to the mouse movements / clicks.<br>
<br>
Regarding visibility of the actor I'm using GetProperty().SetOpacity(0.0) on<br>
an instance of any given actor.<br>
I can't see anything related to movement in the GetProperty() properties, I<br>
believe it's somewhere else?<br>
<br>
Here are most important parts of the code I'm using to generate a single<br>
actor:<br>
<br>
self.ren = vtk.vtkRenderer()<br>
self.ren.SetBackground(0, 0, 0)<br>
self.widget_3d.GetRenderWindow().AddRenderer(self.ren)<br>
<br>
apd=vtk.vtkAppendPolyData()<br>
<br>
for i in xrange(len(coordinates)):<br>
line=vtk.vtkLineSource()<br>
<br>
line.SetPoint1(coordinates[i][0]) # 1st atom coordinates for a given bond<br>
line.SetPoint2(coordinates[i][1]) # 2nd atom coordinates for a given bond<br>
line.SetResolution(21)<br>
apd.AddInput(line.GetOutput())<br>
<br>
mapper = vtk.vtkPolyDataMapper()<br>
mapper.SetInput(apd.GetOutput())<br>
lines_actor = vtk.vtkActor()<br>
lines_actor.SetMapper(mapper)<br>
lines_actor.GetProperty().SetColor(0.7, 0.0, 0.0)<br>
lines_actor.GetProperty().SetOpacity(1.0)<br>
<br>
self.ren.AddActor(lines_actor)<br>
<br>
<br>
I found SetCurrentStyleToTrackballActor(), but I want to control this<br>
behavior from my GUI.<br>
Besides, trackball mode is very inconvenient in my case, with molecules in<br>
"lines" representation (it's hard to pick a single line).<br>
<br>
Thanks,<br>
Piotr Byzia<br>
