I write follow code,but renwin hast not member InitializeFromCurrentContext()?
How to solve this problem,and how to use opengl in vtk?



#ifndef __APPLE_CC__#include <GL/glut.h>#else#include
<glut.h>#endif#include "vtkConeSource.h"#include
"vtkPolyDataMapper.h"#include "vtkRenderWindow.h"#include
"vtkCamera.h"#include "vtkActor.h"#include "vtkRenderer.h"#include
"vtkNew.h"

vtkNew<vtkRenderer> ren;
vtkNew<vtkRenderWindow> renWin;
 void Reshape( int width, int height ){ 	
  renWin->SetSize( width, height );} 	
 void Draw(){ 	
  renWin->Render();
  ren->GetActiveCamera()->Azimuth( 1 );
  glutPostRedisplay();}

int main( int argc, char **argv ){
  // GLUT initialization
  glutInit( &argc, argv );
  glutInitDisplayMode( GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH );
  glutCreateWindow( "VTK-GLUT Example") ;
  glutReshapeFunc( Reshape );
  glutDisplayFunc( Draw );

  // Creation of a simple VTK pipeline
  vtkNew<vtkConeSource> cone;

  vtkNew<vtkPolyDataMapper> coneMapper;
  coneMapper->SetInputConnection( cone->GetOutputPort() );

  vtkNew<vtkActor> coneActor;
  coneActor->SetMapper( coneMapper.GetPointer() );

  ren->AddActor( coneActor.GetPointer() );
  renWin->AddRenderer( ren.GetPointer() );

  // Here is the trick: we ask the RenderWindow to join the current
OpenGL context created by GLUT
  renWin->InitializeFromCurrentContext();

  // Let's start the main GLUT rendering loop
  glutMainLoop();

  return EXIT_SUCCESS;}
