问题描述
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();
};
即使我遵循教程，它总是给我 vtkStandardNewMacro(InteractorStyle); 的错误:
Even though I follow the tutorial, it always gives me below error for vtkStandardNewMacro(InteractorStyle); :
该如何解决?
推荐答案
您需要添加的只是 #include< vtkObjectFactory.h> .该教程从未明确提及过这一点，太糟糕了.
All you need to add is #include <vtkObjectFactory.h>. The tutorial never explicitly mentioned this, too bad.
