[Qt-interest] Restoring default widget brush

[Denis Akhmetzyanov]

I've used another approach in similar cases:

class MyWidget : public QWidget {
public:
     MyWidget() {
          m_defaultWidgetPalette = palette();
     }

     void restorePalette() {
          setPalette(m_defaultWidgetPalette);
     }

private:
     QPalette m_defaultWidgetPalette;
};
