Return value when cancelling QFileDialog::getOpenFileName()?

[jiapei100]

Hi, all:

I'm just wondering what is the return value when canceling QFileDialog::getOpenFileName() ????

The typical example of how to use QFileDialog::getOpenFileName()
can be found at http://pepper.troll.no/s60prerelease...iledialog.html

QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
                                                 "/home",
                                                 tr("Images (*.png *.xpm *.jpg)"));

QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
                                                 "/home",
                                                 tr("Images (*.png *.xpm *.jpg)"));

To copy to clipboard, switch view to plain text mode 

It always return a value of type QString, no matter the user clicks "OK" or clicks "Cancel".

When "cancel", what is the return value? I mean, what is the value of "fileName" when the QFileDialog has been canceled ??


Best Regards

Based on the documentation:

This is a convenience static function that returns an existing file selected by the user. If the user presses Cancel, it returns a null string.

Was this what you were asking for?
