QFileDialog::getExistingDirectory, QFileDialog::getOpenFileName and QFileDialog::getSaveFileName methods do not respect the directory path for native dialogs in OS X

Static methods "QFileDialog::getExistingDirectory", "QFileDialog::getOpenFileName" and "QFileDialog::getSaveFileName" do not respect the directory path for native dialogs in OS X.

The options flag need to be set to "QFileDialog::DontUseNativeDialog" for setting the directory path properly but at a cost of loosing native look and feel and functionality. So ultimately saying these features are not working as expected.
