c++ - 将VkMainWindow保持在底部

我有一个应用程序，运行在Linux上，它由一个VkMainWindow和几个VkWindows组成。所需的行为是使VkMainWindow始终位于底部（因此，所有VkWindows始终位于VkMainWindow的顶部）。现有的代码工作于KDE上的广告，但客户决定它需要在MWM下运行。在MWM下运行时，VkMainWindow在VkWindows上升起。有什么想法吗？
Vkmain窗口：

 MainWindow::MainWindow(MyContainer const &container, ArgList args, Cardinal argc)
       :
            BaseWindow("My Base Window", args, argc,
            _statusWindow(new StatusWindow(container)),
            m_helpDialog(new MainHelpDialog),
            m_container(container),
            m_frame(nullptr),
            m_form(nullptr),
            _button1(nullptr),
            _widget1(nullptr),
            m_button2(nullptr),
            m_widget2(nullptr),
            m_button2(nullptr),
            m_widget3(nullptr),
            m_button3(nullptr),
            m_button4(nullptr),
            m_button5(nullptr),
            m_widget4(nullptr),
            _label1(nullptr),
            _label2(nullptr),
            _label3(nullptr),
            _label4(nullptr),
            _label5(nullptr),
            _label6(nullptr),
            _label7(nullptr)
{
   Display *mainDisplay;
   mainDisplay = XOpenDisplay(0);
   if (mainDisplay)
   {
        m_width = m_mainWindowWidth = 1280;
        m_height = m_mainWindowHeight = 1024;
        XCloseDisplay(mainDisplay);
   }

   XtVaSetValues(m_shellWidget, XmNmwmFunctions, MWM_FUNC_MOVE | MWM_FUNC_MINIMIZE, XmNx, 0, XmNy, 0, NULL);
   m_configFile = currentWorkspace;
}

VKW窗口：

BaseWindow::BaseWindow(string const &name, ArgList args, Cardinal argc,
       unsigned int createOptions, bool createTabStack, bool removeCornerFunctions, bool scrollable, bool workspaceConfigurable)
       :
            VkWindow(name.c_str(), args, argc), _mainForm(0), _mainOffset(
                  MAIN_OFFSET), _buttonSpacing(BUTTON_SPACING), _createOptions(createOptions),
            _createTabStack(createTabStack), _statusText(0), m_buttonBoxForm(0), m_helpForm(0),
            m_okButton(0), m_cancelButton(0), m_applyButton(0), m_applyCb(0), m_okCb(0), m_cancelCb(0),
            m_screenId(INVALID_SCREEN_ID), m_previousTab(0), _tabStack(0), _tabForm(0), m_initialized(false),
            m_shellWidget(0), m_clipWindow(0), _isScrollable(scrollable), m_isValid(true), m_statusOnly(false),
            m_validateOnOk(true), m_validateOnApply(true), m_widgetsMapped(false), m_fooLocked(false), m_isLocked(false),
            m_currentSize(FULL), m_lastSize(0)
{
   Widget parent = mainWindowWidget();
   XtSetValues(parent, args, argc);

   m_shellWidget = parent;
   while (m_shellWidget && !XtIsShell(m_shellWidget))
   {
      m_shellWidget = XtParent(m_shellWidget);
   }

   if (removeCornerFunctions)
   {
       if (m_shellWidget)
       {
         XtVaSetValues(m_shellWidget,
         XmNmwmFunctions, 22,
//         MWM_FUNC_RESIZE | MWM_FUNC_MOVE | MWM_FUNC_MINIMIZE | MWM_FUNC_CLOSE,
         NULL);
         XtAddEventHandler(m_shellWidget, StructureNotifyMask, false, resizeCb, this);
      }
   }
   ...
}

主要：

int main(int argc, char **argv)
{
   ...
   Cardinal ac;
   Arg args[20];
   std::string title("My Client");

   XrmOptionDescRec *optionList = NULL;
   int numOptions = 0;

   app = new VkApp(const_cast<char*>(title.c_str()), &argc, argv, optionList, numOptions);
   ...
   app->run();
   ...
   return (0);
}

最佳答案

解决方案是在主窗口的事件循环中调用VkWindow:lower（）。
