[vtkusers] RenderWindow New Delete New X Error

[Kevin H. Hobbs]

In an application I'm trying to write I want a render window to pop up
every once in a while when there's something to render.

I put the rendering in a function where all of the rendering instances
are created and deleted. 

I got X errors.

Should the minimum example code below just flash empty windows forever
or should it produce errors?

This is gargon on the dashboard.

#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"

#define WSIZE 300

int main( int argc, char * argv[] )
{	
	while (1)
	{
		
		// Render Window
		vtkRenderWindow * render_window = vtkRenderWindow::New();
		render_window->SetSize( WSIZE, WSIZE );
	
		render_window->Render();
	
		render_window->Delete();

	}

	return 0;
}
