problem with tableWidget resizeRowsToContents

**eugenesm** · 1st February 2010, 13:39

I have a problem with auto resize rows. On a form two QTableWidgets, with 4 columns, and a button. Constructor and button have same code. But result is different. Below is code with problem, with some changes (for example change columns count) it works properly), but i can't understand where is problem...

Qt Code:

Switch view

MainWindow::MainWindow(QWidget *parent) :
        QMainWindow(parent),
        ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
fillTable(ui->tableWidget);
}
 
void MainWindow::on_pushButton_clicked()
{
    fillTable(ui->tableWidget_2);
}
 
void MainWindow::fillTable(QTableWidget *tableWidget)
{
 
    tableWidget->setColumnWidth(0,30);
    tableWidget->setColumnWidth(1,200);
    tableWidget->setColumnWidth(2,50);
    tableWidget->setColumnWidth(3,330);
 
    QTableWidgetItem *wi;
 
 
    int rownum = tableWidget->rowCount();
    tableWidget->setRowCount(tableWidget->rowCount()+1);
 
    wi = new QTableWidgetItem("1");
    tableWidget->setItem(rownum,0,wi);
 
    wi = new QTableWidgetItem("");
    wi->setToolTip("");
    tableWidget->setItem(rownum,1,wi);
 
    QString s= "158";
    wi = new QTableWidgetItem(s);
    wi->setToolTip(s);
    tableWidget->setItem(rownum,2,wi);
 
    s= "asdg asdgd agjdj sgjagjsdgj asgdjadg wudi agdu da uidgwgau sdgyugayu gwdyua wd wad awugyd uadyu awydg yw dag dayds asjd ajdajsd sa jdjas djas djasd as"
