Undefined interface

[mero]

Hello
I've got error in cmake:



Error: Undefined interface in line: Q_INTERFACES(QTextObjectInterface)




#include <QObject>
#include <QTextObjectInterface>

class ImageHandler : public QObject, public QTextObjectInterface
{
Q_OBJECT
Q_INTERFACES(QTextObjectInterface)
public:
ImageHandler(TextDocument *doc);
QSizeF intrinsicSize(QTextDocument *doc, int posInDoc, const QTextFormat &format);
void drawObject(QPainter *painter, const QRectF &rect, QTextDocument *doc, int posInDoc, const QTextFormat &format);

private:
QTextObjectInterface *m_defaultImageHandler;

};


what I must add to cmake ? or into code ?

Where is your Q_DECLARE_INTERFACE ?

Please provide a minimal example reproducing the problem.

Where is your Q_DECLARE_INTERFACE ?
This is not my code, I insert 2 files from http://download.hyves.org/kwekker2/HyvesDesktop-src-1.3.tar.gz (HyvesDesktop) for animated icons but I can't compile it.
This problem is part of http://www.qtcentre.org/forum/f-qt-programming-2/t-animation-in-qtextedit-24431.html ...
