display in text browser

[mecrazycoder]

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

multimap<string, string>::iterator iter;
 
                iter = findFile.find(fileToFind);
 
                if ( iter != findFile.end() )
                {
                        do
                        {
                                string temp = iter->second;
                                QString str;
                                str.fromStdString(temp);
                                ui->textBrowser->setText(str);;
                                cout << iter->first << " [DIR] " << iter->second << endl;
                                iter++;
                        }while (iter != findFile.upper_bound ( fileToFind ) );
                }

multimap<string, string>::iterator iter;

                iter = findFile.find(fileToFind);

                if ( iter != findFile.end() )
                {
                        do
                        {
                                string temp = iter->second;
                                QString str;
                                str.fromStdString(temp);
                                ui->textBrowser->setText(str);;
                                cout << iter->first << " [DIR] " << iter->second << endl;
                                iter++;
                        }while (iter != findFile.upper_bound ( fileToFind ) );
                }

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.

Thanks for ur response. But I cant able to figure out the problem. So if possible can you please edit my code

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

QString qstr = QString::fromStdString(str);

QString qstr = QString::fromStdString(str);

Great it worked. Now i want to display results in text browser. But the problem I am facing is text browser display only the last result so can you please tell me how to populate all results(each result per line) in populate. How to integrate text browser with scroll bar. Tanx in advance

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.
