QTableWidget::item return own QTableWidgetItem

Hey guys,
i created an own QTableWidgetItem:
Header:

Code:

---

struct Connections{
    QTableWidgetItem *connectedItem;
    int connection;
};
 
class MyQTableWidgetItem : public QTableWidgetItem
{
public:
    MyQTableWidgetItem();
    void setConnection(MyQTableWidgetItem &connectedItem, int connection);
private:
    QVector <Connections*> ConnectedItems;
 
signals:
 
public slots:
 
};

---

Source:

Code:

---

#include "myqtablewidgetitem.h"
 
MyQTableWidgetItem::MyQTableWidgetItem()
{
}
 
void MyQTableWidgetItem::setConnection(MyQTableWidgetItem &connectedItem, int connection)
{
    bool itemFound = false;
    for(int i = 0;i < this->ConnectedItems.length();i++){
        if(this->ConnectedItems[i]->connectedItem->text() == connectedItem.text()){
            this->ConnectedItems[i]->connection = connection;
            itemFound = true;
            i = this->ConnectedItems.length();
        }
    }
    if(!itemFound){
        Connections *newConnection = new Connections;
        newConnection->connectedItem = &connectedItem;
        newConnection->connection = connection;
        this->ConnectedItems << newConnection;
    }
 
}

---

Now I place this items into a table:
Header:

Code:

---

class AnalyseTable : public QTableWidget
{
    Q_OBJECT
public:
    AnalyseTable(QWidget * parent = 0);
private:
    bool lastRowUsed();
signals:
    void createNewButton(QTableWidgetItem &item);
public slots:
    void InsertNewRow();
 
};
#endif // ANALYSETABLE_H

---

Source:

Code:

---

#include "analysetable.h"
#include <QDebug>
AnalyseTable::AnalyseTable(QWidget *parent) : QTableWidget(parent)
{
    this->setColumnCount(6);
 
 
}
 
bool AnalyseTable::lastRowUsed()
{
    int rows = this->rowCount();
    if(!rows){
        return true;
    }
    if(this->item(rows - 1,0)->text() == "")
        return false;
    return true;
 
}
 
void AnalyseTable::InsertNewRow()
{
    if(this->lastRowUsed()){
        int rows = this->rowCount();
        this->insertRow(rows);
        int column = this->columnCount();
        for(int i = 0 ; i< column; i++){
            this->setItem(rows,i,new MyQTableWidgetItem());
        }
        emit createNewButton(*(this->item(rows,0)));
    }
}

---

My problem now:
emit createNewButton(*(this->item(rows,0)));
this->item() doesnt retrun a MyQTableWidgetItem it return a QTableWidgetItem. How can i fix that? Someone got an idea?

If you know that you have only MyQTableWidgetItems, you can just use static_cast.
Otherwise use dynamic_cast and check if the result is != 0.

Btw, taking the address of a function argument looks very fishy.
Better pass the "connectedItem" already as a pointer, that is what you have at the caller anyway, right?

Thanks its working and I changed the argument :)

You'd better use QTableWidget::setItemPrototype() with your item class. If not, your application will automatically create QTableWidgetItem instead of MyQTableWidgetItem.

Hey,
ahh wow thanks helped me with another jproblem!"!!!
