[vtkusers] vtkOrientationMarkerWidget does not rotate in QVTKWidget

[Eric E. Monson]

Well, I was able to transplant your code into a PyQt4 app. (Since you're using Python, I'm assuming that's what you're using...?) Here's the code that works on my system and a screenshot.

from PyQt4 import QtCore, QtGui
from PyQt4.QtGui import QApplication
import vtk
from vtk.qt4.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor
import sys

class Ui_MainWindow(object):
	def setupUi(self, MainWindow):
		MainWindow.setObjectName("MainWindow")
		MainWindow.resize(603, 553)
		self.centralWidget = QtGui.QWidget(MainWindow)
		self.gridlayout = QtGui.QGridLayout(self.centralWidget)
		self.vtkWidget = QVTKRenderWindowInteractor(self.centralWidget)
		self.gridlayout.addWidget(self.vtkWidget, 0, 0, 1, 1)
		MainWindow.setCentralWidget(self.centralWidget)

class SimpleView(QtGui.QMainWindow):
    
	def __init__(self, parent = None):
	
		QtGui.QMainWindow.__init__(self, parent)
		self.ui = Ui_MainWindow() 
		self.ui.setupUi(self)
		
		self.ren = vtk.vtkRenderer()
		self.ui.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
		iren = self.ui.vtkWidget.GetRenderWindow().GetInteractor()
		
		cube = vtk.vtkCubeSource()
		cube.SetXLength(200)
		cube.SetYLength(200)
		cube.SetZLength(200)
		cube.Update()
		cm = vtk.vtkPolyDataMapper()
		cm.SetInputConnection(cube.GetOutputPort())
		ca = vtk.vtkActor()
		ca.SetMapper(cm)
		
		self.ren.AddActor(ca)

		self.axesActor = vtk.vtkAnnotatedCubeActor();
		self.axesActor.SetXPlusFaceText('R')
		self.axesActor.SetXMinusFaceText('L')
		self.axesActor.SetYMinusFaceText('H')
		self.axesActor.SetYPlusFaceText('F')
		self.axesActor.SetZMinusFaceText('P')
		self.axesActor.SetZPlusFaceText('A')
		self.axesActor.GetTextEdgesProperty().SetColor(1,1,0)
		self.axesActor.GetTextEdgesProperty().SetLineWidth(2)
		self.axesActor.GetCubeProperty().SetColor(0,0,1)
		self.axes = vtk.vtkOrientationMarkerWidget()
		self.axes.SetOrientationMarker(self.axesActor)
		self.axes.SetInteractor(iren)
		self.axes.EnabledOn()
		self.axes.InteractiveOn()
		
		self.ren.ResetCamera()
		
		iren.Start()
        
if __name__ == "__main__":

    app = QApplication(sys.argv)
    window = SimpleView()
    window.show()
    sys.exit(app.exec_())
