## Detailed Description

The QTableWidgetItem class provides an item for use with the QTableWidget class.

Table items are used to hold pieces of information for table widgets. Items usually contain text, icons, or checkboxes

The QTableWidgetItem class is a convenience class that replaces the `QTableItem` class in Qt 3. It provides an item for use with the QTableWidget class.

Items are usually constructed with a table widget as their parent then inserted at a particular position specified by row and column numbers:

            QTableWidgetItem *newItem = new QTableWidgetItem(tr("%1").arg(
                pow(row, column+1)));
            tableWidget->setItem(row, column, newItem);

Each item can have its own background color which is set with the setBackgroundColor() function. The current background color can be found with backgroundColor(). The text label for each item can be rendered with its own font and text color. These are specified with the setFont() and setTextColor() functions, and read with font() and textColor().

Items can be made checkable by setting the appropriate flag value with the setFlags() function. The current state of the item's flags can be read with flags().

See also QTableWidget.

## Related Non-Members

### QDataStream & operator<< ( QDataStream & out, const QTableWidgetItem & item )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Writes the table widget item item to stream out.

This operator uses QTableWidgetItem::write().

See also Format of the QDataStream Operators.

### QDataStream & operator>> ( QDataStream & in, QTableWidgetItem & item )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Reads a table widget item from stream in into item.

This operator uses QTableWidgetItem::read().
