I have a mainwindow of size 480 x 350. The central widget of the main window is a scroll area of dimension 190 x 220. The code for this is as below -

Qt Code: 
  1. scrollArea = new QScrollArea(centralWidget);
  2.         scrollArea->setObjectName(QString::fromUtf8("scrollArea"));
  3.         scrollArea->setGeometry(QRect(210, 20, 191, 221));
  4.         scrollArea->setWidgetResizable(true);
  5.         scrollAreaWidgetContents = new QWidget();
  6.  
  7.         scrollAreaWidgetContents->setObjectName(
  8.         QString::fromUtf8("scrollAreaWidgetContents"));
  9.         scrollAreaWidgetContents->setGeometry(QRect(0, 0, 187, 217));
  10.         scrollArea->setWidget(scrollAreaWidgetContents);
  11.         MainWindow->setCentralWidget(centralWidget);
To copy to clipboard, switch view to plain text mode 

I have a QLabel which is a child of the scrollarea. The code for this is as shown -

Qt Code: 
  1. QLabel* tmp = new QLabel(scrollAreaWidgetContents);
  2.     tmp->setText("Custom Label");
  3.     tmp->setGeometry(QRect( 300,300,60,60));
  4.  
  5.     scrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
  6.     scrollArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
To copy to clipboard, switch view to plain text mode 

So in the application, the scrollarea must show the scroll bars & user must be able to scroll to the qlabel , which will not be in the displayable area.

But when I run it, the scrollarea does not show the scrollbars & hence its not scrollable. How do i solve this issue? Am I doing something wrong here ?
