我有以下代码:
#include <vtkInteractorStyleTrackballCamera.h>
class InteractorStyle : public vtkInteractorStyleTrackballCamera
{
public:
static InteractorStyle* New() {};
vtkTypeMacro(InteractorStyle, vtkInteractorStyleTrackballCamera);
InteractorStyle() {
cout << "test";
}
virtual void OnLeftButtonDown();
virtual void OnKeyPress();
private:
};
vtkStandardNewMacro(InteractorStyle); //error here
void InteractorStyle::OnLeftButtonDown()
{
std::cout << "test";
// Forward events
vtkInteractorStyleTrackballCamera::OnLeftButtonDown();
};
void InteractorStyle::OnKeyPress()
{
// Get the keypress
vtkRenderWindowInteractor *rwi = this->Interactor;
std::string key = rwi->GetKeySym();
// Output the key that was pressed
std::cout << "Pressed " << key << std::endl;
// Forward events
vtkInteractorStyleTrackballCamera::OnKeyPress();
};
即使我关注tutorial ,对于 vtkStandardNewMacro(InteractorStyle);
,它总是给我以下错误:
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
如何解决这个问题?
最佳答案
您只需添加 #include <vtkObjectFactory.h>
.本教程从未明确提及这一点,太糟糕了。
关于c++ - vtkStandardNewMacro 给出错误 C4430 : missing type specifier,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42484095/
