Static Meta Object

[sajis997]

Hello forum,

I have added the class to the project and then i ran qmake . When i try to build the project i get the following error

I seems that there is something wrong with the meta object stuff, but i am not sure where to look into.


Any hint ?

class H3DHierarchyArrowDockGraphicsItem : public QGraphicsItem, public HasToolTip
{
Q_OBJECT

public:

H3DHierarchyArrowDockGraphicsItem should inherit QObject if you want to use Q_OBJECT macro.
