Summary0015966: vtkInteractorStyleTrackballCamera changed after timer added
DescriptionWhen I use the vtkInteractorStyleTrackballCamera, the object movement will stop when the mouse freezes ( with mouse button still down). After I added a timer, the object keep moving even when the mouse stop moving. Only after I release the mouse button, the movement stops.

reproduction code:

#!/usr/bin/env python
import vtk

class vtkTimerCallback():
    def __init__(self):
        self.timer_count = 0
       
    def execute(self,obj,event):
        print(self.timer_count)
        self.timer_count += 1

src = vtk.vtkCubeSource()

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(src.GetOutputPort())

actor = vtk.vtkActor()
actor.SetMapper(mapper)

main_render = vtk.vtkRenderer()
main_render.AddActor(actor)

renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(main_render)

iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)
iren.SetInteractorStyle(vtk.vtkInteractorStyleTrackballCamera())
iren.Initialize()

cb = vtkTimerCallback()
cb.actor = actor
iren.AddObserver('TimerEvent', cb.execute)
timerId = iren.CreateRepeatingTimer(50);
iren.Start()
