QFileDialog with native UI does not show the file name in the file name input field

Hi

When I use QFileDialog with native UI to save a file, the filename is not shown in the file name input field of the dialog. If I switch to non native dialog the file name is displayed correctly.

Sample code:
QFileDialog * fileDialog = new QFileDialog(this,"Test title",filePath,tr("HTML file (*.html)") );
fileDialog ->setFileMode(QFileDialog::AnyFile);
txQFileDialog->setOptions(QFileDialog::DontUseNativeDialog); //if this line is omitted then the file name
//is not shown in the file name input field
fileDialog ->setAcceptMode(QFileDialog::AcceptSave);
fileDialog ->selectFile(fileNameWithoutPath);
