changing column width of QTableWidget

Hello everyone! I'm new to QT and using QT 4.4.2. I wonder why I can't change the width of columns in QTableWidget. I'm trying to do it like this:

ui.setupUi((QMainWindow *)this);
ui.tableWidget->horizontalHeaderItem(3)->setSizeHint(QSize(1000, 100));
QSize sh = ui.tableWidget->horizontalHeaderItem(3)->sizeHint();

The height of the row does really change to 100. The horisontal sizeHint is set to 1000, but the width doesn't change. Can someone help me, pls? Is there another way to change column width?

should QTableView::setColumnWidth () help?

This is a QTableVew method, not QTableWidget.

Have you heard of inheritance?
