Modify model data in QTreeView

[patrik08]

Hello !

I subclassed QItemDelegate, QAbstractItemModel in order to build tree model and see data in QTreeView. Now I need to modify model data, do I have to subclass QTreeView or I can achive it using QTreeView ?

I tested to subclass the item :-( is not easy!
I found a way to make a xml file tree unlimited .... and on a simple class i manage
the domelement & QTreeWidgetItem & the level of tree....

each new Item i add on aa QList<OneTree*> niagaratree; xxx.additem(**) an so i can interact on 2 class... on add item remove rename ecc... on QDomElement you can save all data image html page e other ..on.. QDomElement like a oracle DB :-)....

to delete on item i save the Nr of tree ... and fast save the file xml + reload the GUI whitout the delete nr..item ...

Is moore simple way... and fast....

QList<OneTree*> niagaratree;
typedef QMap<QString, QString> Treevar; 
 
class QTreeWidget;
class QTreeWidgetItem; 
class OneTree : public QObject, public Base_Function
{
    Q_OBJECT
 
public:
        OneTree( QDomElement d , QTreeWidgetItem * top , int lev );
        ...............
private:
    .....
signals: 
     void SendtonewDom(int);
     void SendtoParent(QString);
public slots:
    void MoveToNewDest()
   {
       /////qDebug() << "### ONLISTER emit start    " << ONLISTER;
       emit SendtonewDom(ONLISTER);
   }
 
};

QList<OneTree*> niagaratree;
typedef QMap<QString, QString> Treevar; 

class QTreeWidget;
class QTreeWidgetItem; 
class OneTree : public QObject, public Base_Function
{
    Q_OBJECT
    
public:
        OneTree( QDomElement d , QTreeWidgetItem * top , int lev );
        ...............
private:
    .....
signals: 
     void SendtonewDom(int);
     void SendtoParent(QString);
public slots:
    void MoveToNewDest()
   {
       /////qDebug() << "### ONLISTER emit start    " << ONLISTER;
       emit SendtonewDom(ONLISTER);
   }

};
