运行官网MouseEvent的时候遇到如题所示的问题;
不用cmake,直接在VS下开发的代码如下:
#include <vtkRenderWindow.h> #include <vtkRenderWindowInteractor.h> #include <vtkRenderer.h> #include <vtkSphereSource.h> #include <vtkPolyDataMapper.h> #include <vtkActor.h> #include <vtkSmartPointer.h> #include <vtkPointPicker.h> #include <vtkCamera.h> #include <vtkInteractorStyleTrackballCamera.h> #include <vtkNamedColors.h> #include "vtkAutoInit.h" VTK_MODULE_INIT(vtkRenderingOpenGL2); // VTK was built with vtkRenderingOpenGL2 VTK_MODULE_INIT(vtkInteractionStyle); // Define interaction style class customMouseInteractorStyle : public vtkInteractorStyleTrackballCamera { public: static customMouseInteractorStyle* New(); vtkTypeMacro(customMouseInteractorStyle, vtkInteractorStyleTrackballCamera); virtual void OnLeftButtonDown() { std::cout << "Pressed left mouse button." << std::endl; // Forward events vtkInteractorStyleTrackballCamera::OnLeftButtonDown(); } virtual void OnMiddleButtonDown() { std::cout << "Pressed middle mouse button." << std::endl; // Forward events vtkInteractorStyleTrackballCamera::OnMiddleButtonDown(); } virtual void OnRightButtonDown() { std::cout << "Pressed right mouse button." << std::endl; // Forward events vtkInteractorStyleTrackballCamera::OnRightButtonDown(); } }; vtkStandardNewMacro(customMouseInteractorStyle); int main(int, char *[]) { vtkSmartPointer<vtkSphereSource> sphereSource = vtkSmartPointer<vtkSphereSource>::New(); sphereSource->SetCenter(0.0, 0.0, 0.0); sphereSource->SetRadius(5.0); sphereSource->Update(); vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New(); mapper->SetInputConnection(sphereSource->GetOutputPort()); vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New(); actor->SetMapper(mapper); vtkSmartPointer<vtkNamedColors> colors = vtkSmartPointer<vtkNamedColors>::New(); vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New(); renderer->SetBackground(colors->GetColor3d("Slate_grey").GetData()); renderer->AddActor(actor); vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New(); renderWindow->AddRenderer(renderer); vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New(); renderWindowInteractor->SetRenderWindow(renderWindow); vtkSmartPointer<customMouseInteractorStyle> style = vtkSmartPointer<customMouseInteractorStyle>::New(); renderWindowInteractor->SetInteractorStyle(style); renderWindowInteractor->Initialize(); renderWindowInteractor->Start(); return EXIT_SUCCESS; }
编译的时候提示错误:
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
解决问题的方式是在https://stackoverflow.com/questions/42484095/vtkstandardnewmacro-gives-error-c4430-missing-type-specifier找到的
解决办法为:
包含以下头文件
#include <vtkObjectFactory.h>
