Qt Creator - custom namespace for UI classes

I would like to have a UI class in its own namespace, like ProjectName::MainWindow. Is there some convenient way how to achieve this in Qt Creator, please?

I can open the mainwindow.ui file and change the from "MainWindow" to "ProjectName::MainWindow", which compiles and works. But when I change something in the UI designer, the ui file gets generated again ... with the wrong class name.

When you create new Designer Form Class, specify class name with namespace, e.g. ProjectName::MainWindow. Qt Creator will automatically generate the following code.

MainWindow.h:

namespace ProjectName {
  namespace Ui {
    class MainWindow;
  }
  class MainWindow : public QWidget {
    Q_OBJECT    
  public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();    
  private:
    Ui::MainWindow *ui;
  };
} // namespace ProjectName

MainWindow.ui:

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>ProjectName::MainWindow</class>
 <widget class="QWidget" name="ProjectName::MainWindow">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>400</width>
    <height>300</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>Form</string>
  </property>
 </widget>
 <resources/>
 <connections/>
</ui>

As you see, both MainWindow and Ui::MainWindow are now in ProjectName namespace.
