I figure this is probably a dumb question with a simple answer, but this has been driving me up the wall.

I'm trying to load an SVG image into a QGraphicsScene via a QGraphicsSvgItem (that right so far?), and every time I try to create the QGraphicsSvgItem object, I get this error:


<removed>\Projects\Qt\workspace\SvgContainer\svgco ntainer.cpp:16: error: undefined reference to `_imp___ZN16QGraphicsSvgItemC1ERK7QStringP13QGraph icsItem'


I don't even understand what this is trying to tell me. Here's my code:

code.h
Qt Code: 
  1. #ifndef SVGCONTAINER_H
  2. #define SVGCONTAINER_H
  3.  
  4. #include <QWidget>
  5.  
  6. namespace Ui {
  7. class SVGContainer;
  8. }
  9.  
  10. class SVGContainer : public QWidget
  11. {
  12.     Q_OBJECT
  13.  
  14.     public:
  15.         explicit SVGContainer(QWidget *parent = 0);
  16.         ~SVGContainer();
  17.  
  18.     private:
  19.         Ui::SVGContainer *ui;
  20. };
  21.  
  22. #endif // SVGCONTAINER_H

  6.     QWidget(parent),
  7.     ui(new Ui::SVGContainer)
  8. {
  9.     ui->setupUi(this);
  10.  
  11.     QGraphicsScene *scene = new QGraphicsScene(this);
  12.     ui->graphicsView->setScene(scene);
  13.     QGraphicsSvgItem *svgItem = new QGraphicsSvgItem("assets\\outline.svg"); // <- Errors happen here
  14.     scene->addItem(svgItem);
  15. }
  16.  
  17. SVGContainer::~SVGContainer()
  18. {
  19.     delete ui;
  20. }
