Hi,
i am not sure if Ogre influence or no
but i have the mouse press and mouse release event that work
that's it's code
mouseReleaseEvent(QMouseEvent* e):
Qt Code: 
  1. void My_app::mouseReleaseEvent(QMouseEvent* e)
  2. {
  3. 	 if(!e->buttons().testFlag(Qt::LeftButton))
  4.     {
  5.         oldPos = QPoint(invalidMousePoint);
  6.         e->accept();
  7.     }
  8.     else
  9.     {
  10.         e->ignore();
  11.     }
  12.     emit mouseRelease(e);
  13. }
To copy to clipboard, switch view to plain text mode 
mousePressEvent(QMouseEvent* evt):
Qt Code: 
  1. if(evt->button() == Qt::LeftButton)
  2. 	{
  3.  
  4.  
  5.    Ogre::Real offsetX =(double)evt->pos().x()/(double)width();
  6.    Ogre::Real offsetY=(double) evt->pos().y()/(double)height();
  7. move_object(double offsetX ,double offsetY)
  8. 	}
  9. emit mousePress(evt);
  10. }
To copy to clipboard, switch view to plain text mode 
it work mouse press event
but mouse move event
Qt Code: 
  1. oid QOgreRenderWindow::mouseMoveEvent(QMouseEvent *e)
  2. {
  3.  
  4. 	if(e->buttons().testFlag(Qt::LeftButton))
  5.     {
  6.          Ogre::Real offsetX =(double)e->pos().x()/(double)width();
  7.    Ogre::Real offsetY=(double) e->pos().y()/(double)height();
  8.  
  9.   move_object(offsetX,offsetY);
  10.  e->accept();
  11. }
  12. emit mouseMove(e);
  13. }
To copy to clipboard, switch view to plain text mode 
the mouse work just when i pree when i move nothing it work
