Scroll bar problems

[mannu]

Hey

i ma developing an applicaqtion ofr a symbian device. i have set minimum size to all the widgets and ensured that they are all placed in a groupBox. But i am not able to get a clear layout, neither on device nor on simulator. Here is the code i am working with

@
QScrollArea *scrollArea = new QScrollArea;

ui->centralWidget->adjustSize();
QFormLayout *frmLout = new QFormLayout;
frmLout->addWidget(ui->groupBox);
frmLout->addWidget(ui->groupBox_2);
frmLout->addWidget(ui->groupBox_3);
frmLout->addWidget(ui->groupBox_4);
frmLout->addWidget(ui->groupBox_5);
frmLout->addWidget(ui->groupBox_6);
frmLout->addWidget(ui->groupBox_7);
scrollArea->widgetResize
scrollArea->setLayout(frmLout);
scrollArea->widgetResizable();
QScrollBar *scrlBar = new QScrollBar;
scrollArea->setVerticalScrollBar(scrlBar);
setCentralWidget(scrollArea);

I need to add a scroll bar such that if the device is not able to display all the data on its screen, they can use the scrollBar. Kindly help.
