I am using QT4 ( Windows)

I am trying to show help through a click of pushbutton . Help file ( first one ) is required to be displayed in a Textbrowser popup where onward one canm follow the links. I have made the first page in html and links are also html .

I am using the following code

Qt Code: 
  1. steg::steg(QWidget *parent)
  2.      : QDialog(parent)
  3.  {
  4.      ui.setupUi(this);  
  5.  
  6. connect(ui.helpbutton, SIGNAL(clicked()), this, SLOT(help()));
  7.  
  8. }
  9.  
  10. void steg::help()
  11. {  
  12.  
  13.     QTextBrowser *sourceViewer = new QTextBrowser(0);
  14.     //sourceViewer->setSource(ui.datalineEdit->text());
  15.     sourceViewer->resize(600, 600);
  16.     sourceViewer->show();
  17.  
  18.  }
To copy to clipboard, switch view to plain text mode 
In fact how to give setsource().For a normal html file or even a doc file how to give it as url since setsource( const url&) is to be given.
