    Unhappy display in text browser

    I am noob in QT as well as C++. Rite now I am trying to display value of iter->second but its not working. Here is the small piece of code
    Qt Code:
    1. multimap<string, string>::iterator iter;
    2.  
    3. iter = findFile.find(fileToFind);
    4.  
    5. if ( iter != findFile.end() )
    6. {
    7. do
    8. {
    9. string temp = iter->second;
    10. QString str;
    11. str.fromStdString(temp);
    12. ui->textBrowser->setText(str);;
    13. cout << iter->first << " [DIR] " << iter->second << endl;
    14. iter++;
    15. }while (iter != findFile.upper_bound ( fileToFind ) );
    16. }
    To copy to clipboard, switch view to plain text mode 
    Please help me out

    You need to convert it from a number to a string.
    Check out the QString documentation, specifically something like QString::number or the QString arg(...) function.

    'fromStdString' is static method, so you use it like so:

    Qt Code:
    1. QString qstr = QString::fromStdString(str);
    To copy to clipboard, switch view to plain text mode

    Sorry, I thought second was a number (seconds).

    The documentation for QTextBrowser is at http://doc.trolltech.com/4.7/qtextbrowser.html, and you can find all its methods here. Also, since QTextBrowser inherits QTextEdit, you can also use the methods in http://doc.trolltech.com/4.7/qtextedit.html.

    Anyway, setText() removes old text before adding new ones. To add text without removing the old ones, use append().

    If I'm not mistaken, the QTextBrowser should automatically have a scroll bar.
