Subclassing QTreeWidgetItem

[kouros]

Hello can anyoune explain me how to subclass QTreeWidgetIem? Please help me.

Here is the compiler error.
@
/home/serge/Desktop/build-openhomedesigner-Desktop-Debug/moc_treewidgetitem.cpp:52: error: 'staticMetaObject' is not a member of 'QTreeWidgetItem'
{ &QTreeWidgetItem::staticMetaObject, qt_meta_stringdata_TreeWidgetItem,
^
@

Here is my header and my source file.
@
#ifndef TREEWIDGETITEM_H
#define TREEWIDGETITEM_H

#include <QtCore>
#include <QtGui>

class TreeWidgetItem : public QTreeWidgetItem{
Q_OBJECT

public:
explicit TreeWidgetItem(QTreeWidget *parent = 0, int type = Type);
TreeWidgetItem(QTreeWidgetItem *parent = 0, int type = Type);

protected:

private:

public slots:

protected slots:

private slots:

signals:
};

#endif // TREEWIDGETITEM_H
@

@
#include "treewidgetitem.h"

TreeWidgetItem::TreeWidgetItem(QTreeWidget *parent, int type) : QTreeWidgetItem(parent, type){
}

TreeWidgetItem::TreeWidgetItem(QTreeWidgetItem *parent, int type) : QTreeWidgetItem(parent, type){
}
@

I am subclassing every other Widget without problems, I don't know where my error is...

Hi,

Simple: QTreeWidgetItem is not a QObject

[kouros]

Yeah and how do I reimplement it? Not very useful.

Either:

• Don't put QObject related stuff in your sub-class
• Inherit from both QTreeWidgetItem and QObject, which generally is a bad idea if you plan to have many data in your QTreeWidget. However if you want to do it anyway, the first class that must be inherited is QObject.
