Is the interactor in the QVTKWidget initialized and started by default?<br>
<br>
I've been trying to add a VTKSplineWidget on request, but I keep getting the<br>
following error when I try and start the interactor after creating the<br>
SplineWidget.<br>
<br>
ERROR: In /opt/wai/vth/vth-5.4.2/GUISupport/Qt/QVTKWidget.cxx, line 1055<br>
QVTKInteractor (0x3864640): QVTKInteractor cannot control the event loop<br>
<br>
Then when I run the mouse of the VTK window, the code crashes out.<br>
<br>
The example on the Wiki only cover standalone VTK windows, not the<br>
QVTKWidget. Do I have to create all the Widgets I want in the construction<br>
of the window and then turn them on and off as and when I need them, in<br>
order for the interactor to work?<br>
<br>
Cheers<br>
