QFileDialog::DontUseNativeDialog is not working

qt qfiledialog

I have an issue with a simple program. I'm opening a QFileDialog this way:

QFileDialog fileDialog(this);
fileDialog.setAcceptMode(QFileDialog::AcceptOpen);
if (!fileDialog.exec())
return;

However it shows a Qt dialog instead the native Windows dialog. I'm using Windows 7 x64 and I really do preferr the native dialog instead of Qt dialog because it is a lil' bit more fancy. However I've read and I found that this can be changed by using:

fileDialog.setOption(QFileDialog::DontUseNativeDialog, false);

The fact is that I'm not getting the native Windows dialog but the Qt one, so that option is not working... Anyone knows how to solve this issue without using the static members?

I don't really want to use the static members because they have a kind of memory leak problem or something because if you open repeatedly new dialogs with the static member the memory used by your program increases and increases, however, using the dialog previously stored with a pointer doesn't have this problem.

So, if someone has an answer about this both things (Native dialog and memory leak problem) plz tell me.

Thanks.

The native dialogs don't support the full array of features exposed by the QFileDialog class. That's why they are only available through the static short-cut functions called getOpenFileName(), getSaveFileName() etc'. If you're using these functions and still don't want to see the native dialog, you use the DontUseNativeDialog flag.
