QT+vtk的一个错误：无法解析的外部命令

程序功能很简单，点击button，然后选取图片，在QVTKWidget控件中显示图片。
下面是代码：



test.h 

#ifndef TEST_H

#define TEST_H



#include <QtWidgets/QMainWindow>

#include "ui_test.h"

#include<vtkSmartPointer.h>



class vtkImageViewer2;

class vtkRenderer;

//class QPushButton;

class QVTKWidget;





class test : public QMainWindow

{

	Q_OBJECT



public:

	test(QWidget *parent = 0);

	~test();



private:

	Ui::testClass ui;



private slots:

	void onOpenSlot();



private:

	vtkSmartPointer<vtkImageViewer2> m_pImageViewer;

	vtkSmartPointer<vtkRenderer> m_pRenderer;

	//QPushButton pushButton;

	QVTKWidget m_QVTKWidget;

};

#endif // TEST_H



test.cpp

#include "test.h"

#include<qfiledialog.h>

#include<qdir.h>

#include<vtkRenderWindow.h>

#include<vtkRenderer.h>

#include<vtkImageViewer2.h>

#include<QVTKWidget.h>

#include<vtkJPEGReader.h>

#include<vtkImageActor.h>

#include<ui_test.h>

#include<qpushbutton.h>





test::test(QWidget *parent)

	: QMainWindow(parent)

{

	ui.setupUi(this);



	m_pImageViewer=vtkSmartPointer<vtkImageViewer2>::New();

	m_pRenderer=vtkSmartPointer<vtkRenderer>::New();



	//设置m_QVTKWidget的渲染器

	m_QVTKWidget.GetRenderWindow()->AddRenderer(m_pRenderer);



	//连接打开的信号与相应的槽

	connect(ui.pushButton,SIGNAL(triggered()),this,SLOT(onOpenSlot()));



}



test::~test()

{



}



void test::onOpenSlot()

{

	QString filter;

	filter="JPEG image file(*.jpg *.jpeg)";



	QDir dir;

	QString fileName=QFileDialog::getOpenFileName(this,QString(tr("打开图像")),dir.absolutePath(),filter);

	if(fileName.isEmpty()==true)return;



	//支持带中文路径的读取

	QByteArray ba=fileName.toLocal8Bit();

	const char*fileName_str=ba.data();



	//用vtkIPEGReader读取JPG图像

	vtkSmartPointer<vtkJPEGReader>reader=vtkSmartPointer<vtkJPEGReader>::New();

	reader->SetFileName(fileName_str);



	//将reader的输出作为m_pImageViewer的输入，并设置m_ImageViewer与渲染器m_pRenderer的关联

	m_pImageViewer->SetInputData(reader->GetOutput());

	m_pImageViewer->UpdateDisplayExtent();

	m_pImageViewer->SetRenderWindow(m_QVTKWidget.GetRenderWindow());

	m_pImageViewer->SetRenderer(m_pRenderer);

	m_pImageViewer->SetupInteractor(m_QVTKWidget.GetRenderWindow()->GetInteractor());

	m_pImageViewer->SetSliceOrientationToXY();//默认就是这个方向的

	m_pImageViewer->GetImageActor()->InterpolateOff();

	m_pRenderer->ResetCamera();

	m_pRenderer->DrawOn();

	m_QVTKWidget.GetRenderWindow()->Render();

}



main.cpp

#include "test.h"

#include <QtWidgets/QApplication>



int main(int argc, char *argv[])

{

	QApplication a(argc, argv);

	test w;

	w.show();

	return a.exec();

}

出现了错误
