[Qt-interest] Problem with selecting a directory

[fares.abdullah at sosco.com]

Hi Nouman,

Yes, it is the QT version.

See here for the QT 3.3 version of this method: http://doc.trolltech.com/3.3/qfiledialog.html#getExistingDirectory

The example there is:
    QString s = QFileDialog::getExistingDirectory(
                    "/home",
                    this,
                    "get existing directory",
                    "Choose a directory",
                    TRUE );

Cheers,

- Fares

Thanks Ferenc but my compiler is giving me following error:

error: 'ShowDirsOnly' is not a member of 'QFileDialog'

My qt version is 3.3.8b....meaning 'not' latest. Does dat have anything to do with the error.

Try this:

QString dir =
QFileDialog::getExistingDirectory(
       this,
       tr("Open Directory"),
       "/home",
       QFileDialog::ShowDirsOnly);

This pops-up a file dialog where you can select (any _existing_)
directories just as you would from any other application. Then you can
pass *dir* to setCurrent() or do with it whatever you like! HTH
