QPlatformTheme::DialogType

[uwerat]

QPlatformTheme::createPlatformDialogHelper allows to fall back on native dialogs:

class  QPlatformTheme
{
   enum DialogType {
        FileDialog,
        ColorDialog,
        FontDialog,
        MessageDialog
    };

    virtual bool usePlatformNativeDialog(DialogType type) const;
    virtual QPlatformDialogHelper *createPlatformDialogHelper(DialogType type) const;
};
