用qt编译下面程序是总是出现以下错误D:\project\ProjectMainWindow\ProjectMainWindow.cpp:21: error: C2065: “m_QVTKWidget”: 未声明的标识符；
下面是代码：
test.cpp
#include "ProjectMainWindow.h"
#include #include
#include
#include <vtkRenderer.h>#
include
#include <QVTKWidget.h>#
include #include
ProjectMainWindow::ProjectMainWindow(){ setupUi(this);
m_pImageViewer = vtkSmartPointer< vtkImageViewer2 >::New(); m_pRenderder = vtkSmartPointer< vtkRenderer >::New();
// 设置m_QVTKWidget的渲染器 m_QVTKWidget->GetRenderWindow()->AddRenderer(m_pRenderder);
//连接打开的信号与相应的槽 connect( m_OpenAction, SIGNAL( triggered() ), this, SLOT( onOpenSlot() ) );}
ProjectMainWindow::~ProjectMainWindow(){}
void ProjectMainWindow::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vtkJPEGReader读取JPG图像 vtkSmartPointer reader = vtkSmartPointer::New(); reader->SetFileName(fileName_str);
// 将reader的输出作为m_pImageViewer的输入，并设置m_pImageViewer与渲染器m_pRenderer的关联 m_pImageViewer->SetInput(reader->GetOutput()); m_pImageViewer->UpdateDisplayExtent(); m_pImageViewer->SetRenderWindow(m_QVTKWidget->GetRenderWindow()); m_pImageViewer->SetRenderer(m_pRenderder); m_pImageViewer->SetupInteractor(m_QVTKWidget->GetRenderWindow()->GetInteractor()); m_pImageViewer->SetSliceOrientationToXY(); //默认就是这个方向的 m_pImageViewer->GetImageActor()->InterpolateOff(); m_pRenderder->ResetCamera(); m_pRenderder->DrawOn(); m_QVTKWidget->GetRenderWindow()->Render();}

你这样贴代码自己能看懂么

m_QVTKWidget
是要把UI中的QVTK控件改名为m_QVTKWidget
所以你在代码中找不到
