[vtkusers] giving renderwindow a name

[Bryan P. Conrad]

I have only done this in python, not C++, but I think the trick is to use the method "SetWindowName" and it has to be called *after* the renderWindow is rendered the first time.  See the python code below (copied from David's C++ example), for a version that works on my machine.

import vtk

def main():
    #Create a sphere
    sphereSource = vtk.vtkSphereSource()
    sphereSource.SetCenter(0.0, 0.0, 0.0)
    sphereSource.SetRadius(5)
    
    #Create a mapper and actor
    mapper = vtk.vtkPolyDataMapper()
    mapper.SetInputConnection(sphereSource.GetOutputPort())
    actor = vtk.vtkActor()
    actor.SetMapper(mapper)
    
    # Setup a renderer, render window, and interactor
    renderer = vtk.vtkRenderer()
    renderWindow = vtk.vtkRenderWindow()
    #renderWindow.SetWindowName("Test")
    
    renderWindow.AddRenderer(renderer);
    renderWindowInteractor = vtk.vtkRenderWindowInteractor()
    renderWindowInteractor.SetRenderWindow(renderWindow)
    
    #Add the actor to the scene
    renderer.AddActor(actor)
    renderer.SetBackground(1,1,1) # Background color white
    
    #Render and interact
    renderWindow.Render()
    
    #*** SetWindowName after renderWindow.Render() is called***
    renderWindow.SetWindowName("Test")
    
    renderWindowInteractor.Start()


if __name__ == '__main__':
    main()

I setup an example if anyone cares to play with it to get it to work:
