[Paraview] pqViewManager in Clone2

[Alexis Chan]

Hi

 I tried to use the recommended method below in my ParaView plugin:



 // Get Application Core
  pqApplicationCore* core = pqApplicationCore::instance();

  // Get Object Builder to create new Views, Server etc
  pqObjectBuilder* builder = core->getObjectBuilder();

  // Get the Server Manager Model so that we can get current server

  pqServerManagerModel* serverManager = core->getServerManagerModel();

  if (serverManager->getNumberOfItems<pqServer*>()== 1) // Assuming
that there is only 1 server

  {
	  pqServer* server = serverManager->getItemAtIndex<pqServer*>(0);

	  if (serverManager->getNumberOfItems<pqView*> () == 1) // Assuming
that there is only 1 view created
	  {
		  pqView* view1 = serverManager->getItemAtIndex<pqView*>(0);

		
		  // Get QWidget from first view

		  QWidget* viewWidget = view1->getWidget();
		  //Create GridLayout Widget from first view's widget
		  QGridLayout* gl  = new QGridLayout(viewWidget);

                                  //create second view

		  pqRenderView* view2 = qobject_cast<pqRenderView*>(
	                  builder->createView(pqRenderView::renderViewType(), server));
                                  //Add second view's widget to gridlayout


		  gl->addWidget(view2->getWidget(),1,1);

		  //Create third view
		
                                   //create third view
		  pqRenderView* view3 = qobject_cast<pqRenderView*>(
	                  builder->createView(pqRenderView::renderViewType(), server));


                                  //Add third view's widget to gridlayout
	                   gl->addWidget(view3->getWidget(),2,2);
	  }
  }

The debugger fails at
pqRenderView* view3 = qobject_cast<pqRenderView*>(
	                  builder->createView(pqRenderView::renderViewType(), server));

pqObjectBuilder.cxx : pxm->RegisterProxy("views", name.toAscii().data(), proxy);
qwidget.h: inline QSize QWidget::size() const { return data->crect.size(); }

because data is null.


name.toAscii is "RenderView3".

Can someone let me know what I mess up in the code? Thanks.
