Hi
i integrate ogre with qt
i have now this code

my problem now is i want add object with mouse in the windows i do not know how i do that

when i was work only with ogre i make it like that

Qt Code: 
  1. bool BaseApplication::mousePressed( const OIS::MouseEvent &arg, OIS::MouseButtonID id )
  2. {
  3. 	MarkerNode= mSceneMgr->getRootSceneNode()->createChildSceneNode();
  4.     if (mTrayMgr->injectMouseDown(arg, id)) return true;
  5.     //mCameraMan->injectMouseDown(arg, id);
  6. 	switch(id) {
  7.         case OIS::MB_Left:
  8.             /*Ogre::Entity**/ ent_marker = mSceneMgr->createEntity( Ogre::SceneManager:: PT_SPHERE);
  9.  
  10. 			//createNode(ent_marker); 
  11. 			 MarkerNode->attachObject(ent_marker);
  12. 			 MarkerNode->setScale(0.1f, 0.1f, 0.1f);
  13. 			  Ogre::Real screenWidth = Ogre::Root::getSingleton().getAutoCreatedWindow()->getWidth();
  14.    Ogre::Real screenHeight = Ogre::Root::getSingleton().getAutoCreatedWindow()->getHeight();
  15.  
  16.    // convert to 0-1 offset
  17.    Ogre::Real offsetX = arg.state.X.abs / screenWidth;
  18.    Ogre::Real offsetY = arg.state.Y.abs / screenHeight;
  19.  
  20.    // set up the ray
  21.    Ogre::Ray mouseRay = mCamera1->getCameraToViewportRay(offsetX, offsetY);
  22.  
  23.    // check if the ray intersects our cube
  24.    // intersects() will return whether it intersects or not (the bool value) and
  25.    // what distance (the Real value) along the ray the intersection is
  26.    std::pair<bool, Ogre::Real> result = mouseRay.intersects(CubeNode->getAttachedObject (0) ->getBoundingBox());
  27.  
  28.  
  29.     if(result.first) {
  30.            // if the ray intersect the plane, we have a distance value
  31.            // telling us how far from the ray origin the intersection occurred.
  32.            // the last thing we need is the point of the intersection.
  33.            // Ray provides us getPoint() function which returns a point
  34.            // along the ray, supplying it with a distance value.
  35.  
  36.            // get the point where the intersection is
  37. 		Ogre:: Vector3 point = mouseRay.getPoint(result.second);
  38.  
  39.            // position our sphere 
  40.        /* Ogre::Entity**/ //ent_marker->setPosition(point);
  41. 	//MarkerNode->setPosition(point);
  42.  
  43.  
  44. 			 MarkerNode->setPosition(point);
  45.  
  46.  
  47.             //break;
  48. 	}
  49.     }

and i initialyse OIS like that
Qt Code: 
  1. Ogre::LogManager::getSingletonPtr()->logMessage("*** Initializing OIS ***");
  2.     OIS::ParamList pl;
  3.     size_t windowHnd = 0;
  4.     std::ostringstream windowHndStr;
  5.  
  6.     mWindow->getCustomAttribute("WINDOW", &windowHnd);
  7.     windowHndStr << windowHnd;
  8.     pl.insert(std::make_pair(std::string("WINDOW"), windowHndStr.str()));
  9.  
  10.     mInputManager = OIS::InputManager::createInputSystem( pl );
  11.  
  12.     mKeyboard = static_cast<OIS::Keyboard*>(mInputManager->createInputObject( OIS::OISKeyboard, true ));
  13.     mMouse = static_cast<OIS::Mouse*>(mInputManager->createInputObject( OIS::OISMouse, true ));*/
