QTableWidget : personal widget as header?
===

What is the easiest way (without subclassing QTableWidget if possible) to put a personnal Widget (which is a group of QPixmap + QLabel + QComboBox in my case) as headers in a QTableWidget ?

It is relatively easy to do it for the array content as we have the function `QTableWidget::setCellWidget(int row, int column, QWidget * widget)`, but for the headers, we only have `QTableWidget::setHorizontalHeaderItem (int column, QTableWidgetItem * item)`

Thank you very much !
