[vtkusers] Deleting / Hiding all the objects in a window

[Baliki baliki]

I had the same problem! Calling Render() on the Renderer should work...

>From Documentation:

********
virtual void vtkRenderer::Render (
 )  [virtual]

Create an image. This is a superclass method which will in turn call the
DeviceRender method of Subclasses of
vtkRenderer<http://www.vtk.org/doc/nightly/html/classvtkRenderer.html>


virtual void vtkRenderWindow::Render (
 )  [virtual]

Ask each renderer owned by this RenderWindow to render its image and
synchronize this process.

Implements vtkWindow<http://www.vtk.org/doc/nightly/html/classvtkWindow.html#acb783e66948656035da1bc0bf747c13a>
.

Reimplemented in
vtkXMesaRenderWindow<http://www.vtk.org/doc/nightly/html/classvtkXMesaRenderWindow.html#abb3258748e55ad41f3d6a6c4b145814c>,
and vtkXOpenGLRenderWindow<http://www.vtk.org/doc/nightly/html/classvtkXOpenGLRenderWindow.html#a33183ba56fc43126a34d2d82b1289988>
.

 ********

My RenderWindow has only one Renderer.
So, RenderWindow->Render() should be the same as Renderer->Render(),
according to the documentation...
