SelectFile() is returning NULL

Hello,
I want to retrieve selected file name from file dialog. I am using selectfile() function for this but it is not returning the value.
Below is the code snippet please let me know what is the problem.

Code:

---

SavePage()
{
	QFileDialog dialog(this);
	dialog.setMinimumSize(240, 320);
	dialog.setAcceptMode (QFileDialog::AcceptSave);
	dialog.resize(240,320);
	dialog.setConfirmOverwrite(false);
 
	QString fileName;
 
	if (dialog.exec())
	      dialog.selectFile (fileName);
	else
	      return;
 
	// Open a file and Save in it 
	QFile file(fileName);
	file.open(QIODevice::WriteOnly);
	QTextStream ts( &file);
 
}

---

according to you code fileName is an empty string, line 9.
QFileDialog::selectFile takes a const reference, so it should not modify fileName.

Which function should I used to retrieve file name of the selected file?

QFileDialog::selectedFiles.

...or use the static QFileDialog::getSaveFileName() and check if empty.

I tried using this getSavefileName() static method but I was not able to resize it's window size. I am developing application for mobile device hence I want to resize the dialog window as per my device resolution.

Thanks!! Problem is solved.
