How to set cell size of QTableWidget?

[sonichy]

Solved:

ui->tableWidget->horizontalHeader()->setDefaultSectionSize(60);    // width
ui->tableWidget->verticalHeader()->setDefaultSectionSize(60);      // height
......
ui->tableWidget->setCellWidget(r,c,widget);

try:

QTabelWIdgetItem* item = new QTableWidgetItem;
   item->setSizeHint( widget->sizeHint() );
ui->tableWidget->setCellWidget(r,c,item);
ui->tableWidget->setCellWidget(r,c,widget);

For the people ending here from google.
The solution that avoids the awful setCellWidget is using a QStyledItemDelegate subclass that reimplements sizeHint()
