How to set window flags for QFileDialog

[Qingshui Kong]

Hello.

Could somebody help me.

I want to set window flags of QFileDialog. But it doesn't work.

For example, setWindowFlags(Qt::FramelessWindowHint); The file dialog still has window frame. But it works for QMessageBox.

It is the same both on Windows and Ubuntu.

My environment.

Windows 7

Ubuntu 16.04

Thanks
