How to use verticalScrollBar? [SOLVED]

[micamica]

I added scrollArea and verticalScrollBar but not functioning as I expected.
Need code for it. What should I set? Value?
I want the scrollBar to display unseen part of the page...
Need help! >.<

Just add you widget to the QScrollArea, and that's all you are done. vertical / horizontal scroll bars appear as and when needed. The basic example from documentation is

QLabel *imageLabel = new QLabel; //replace this with your widget
 QImage image("happyguy.png");
 imageLabel->setPixmap(QPixmap::fromImage(image));
 
 scrollArea = new QScrollArea;
 scrollArea->setBackgroundRole(QPalette::Dark);
 scrollArea->setWidget(imageLabel);//set your widget on to QScrollArea

QLabel *imageLabel = new QLabel; //replace this with your widget
 QImage image("happyguy.png");
 imageLabel->setPixmap(QPixmap::fromImage(image));

 scrollArea = new QScrollArea;
 scrollArea->setBackgroundRole(QPalette::Dark);
 scrollArea->setWidget(imageLabel);//set your widget on to QScrollArea

To copy to clipboard, switch view to plain text mode
