title: QT How to embed an application into QT widget
body: <p>In our project we have three independent applications, and we have to develop a QT control application that controls these three applications. The main window will be seperated to three sub windows - each one display another one application.<br>
  I thought to use <a href="http://harmattan-dev.nokia.com/docs/library/html/qt4/qx11embedwidget.html#details">QX11EmbedWidget</a> and <a href="http://harmattan-dev.nokia.com/docs/library/html/qt4/qx11embedcontainer.html">QX11EmbedContainer</a> widgets, but two problems with that: </p>
  
  <ol>
  <li>The QX11Embed* is based on X11 protocol and I dont know if it's supported on non-x11 systems like Windows OS.</li>
  <li>Since QT 5 these classes are not existing, and the QT documentation doesn't mention why.</li>
  </ol>
  
  <p>So that I dont know whether to use it or not - I'll be happy to get an answers.<br>
  In addition, I see that the QT 5.1 contains <a href="http://doc-snapshot.qt-project.org/qt5-stable/qtwidgets/qwidget.html#createWindowContainer">QWidget::createWindowContainer();</a> function that in some posts it looks like this should be the replacement to the X11Embed. Can anyone please explian me more how can I use this function to create a QT widget that will run another application (a Calculator for example) inside its?</p>
  
  <p>I have searched a lot in Google, and didn't find answers to my Qs.<br>
  Can anyone please help me? Am I on the right way?<br>
  Thanks!</p>
