Question

我想将两个QWidgets纳入利用XLib创建的窗口。我写了这一法典:

// Assume all the necessary headers included

int main(int argc, char *argv[])
{
   QApplication app(argc, argv);

   // Create widget 1
   QWidget widget1 ; 
   widget1.setGeometry(44,44,666,666);
   widget1.show();

   // Create widget 2   
   QWidget widget2 ;
   widget2.setGeometry(144,144,666,666);
   widget2.show();      

   Display *display = XOpenDisplay( 0 ); // 0 parameter for default values

   if ( display != NULL )
   {
      // Create the x11 window using XLib
      Window w = XCreateWindow(display, DefaultRootWindow(display), 
      0, 0, 1200, 1100, 0,CopyFromParent, CopyFromParent, CopyFromParent, 0, 0);

      XMapWindow(display, w);
      XFlush(display);

      XReparentWindow(display, widget1.winId(), w, 0, 0);
      XReparentWindow(display, widget2.winId(), w, 1, 10);
  }

  else
      std::cout << "Error: Opening display" << std::endl ;

      return app.exec();
}

我能够成功地实施这一方案,但这些植被并未融入我创建的X11窗口。所有这三件事都在制造,但都是独立的。这些植被没有落到窗户中。

Answer 1

下面将表明,或许你需要考虑显示植被的顺序,以便赢得这些植被。这对你们的植被来说是一种可以传给XRengWindow的东西。

Answer 2

As alternate solution, you can to use QX11EmbedWidget instead QWidget in qt application and XEmbed protocol in XLib application, such as doing this QX11EmbedContainer. This solution has a plus: you can realise different window in different processes.
