VTK initialization code learning 1

// Dialog initialization function OnInitDialog（）

	//  Do this 
	SetIcon(m_hIcon, TRUE);			//  Set the big icon

	GetDlgItem(IDC_STATIC)->GetWindowRect(&rec1);// Get the rectangular size of the window 
	cv::resizeWindow("1", rec1.Width(), rec1.Height());// take opencv Window settings and MFC The created rectangle is the same size 
	HWND hWnd = (HWND)cvGetWindowHandle("1");// take cv Get the handle of the window , Cast to MFC The handle of

	// take VTK Some information displayed , close 
	 Just started Qt To write VTK In the program , Always pop up vtkOutputWindow window ,
	// Although it has no effect on the program results , But it's very annoying , Taste 
	//  Test image VC In the same way GlobalWarningDisplayOff() Function to close ,
	//  Only some information can be closed , But cannot close because Qt and VTK Some usage warnings for version update .
	//  After various verification , All warnings need to be turned off , Need to be in use CMake To configure VTK Installation sln Time selection 
	// VTK_LEGACY_SILENT by on. If you have installed it ,
	//  It needs to be reused CMake To configure , And install it again .
	mpc.iren->GlobalWarningDisplayOff();
	// Specific use process ： Create an interleaver iren
	//1. Create an interleaver vtkRenderWindowInteractor object iren;
	// 2. To object iren Set up SetRenderWindow() Windows that require interaction ;
	// 3. To object iren Appoint SetInteractorStyle() Specific ways of interaction , If not specified , The interleaver will use the default interaction mode ;
	// 4. To the object iren initialization Initialize, call Start Start interacting ;

	//dlp initialization , How to call ？？？？？
	// The parameter control will be calibrated , The pointer goes to plistb
	plistb = ((CListBox*)GetDlgItem(IDC_LIST1));
	return TRUE;  //  Unless you set the focus to the control , Otherwise return to  TRUE
