Get mouse events in MAC

[vinayaka]

We got the mouse events on the title bar using the following code in windows

bool RightSideBar::winEvent(MSG *msg, long *result)
{
    if (msg->message == WM_NCLBUTTONUP)
     {
      //here can catch the leftmousedown event on titlebar
         qDebug()<<"Title Bar Button Down";
     }
    return false;
}

bool RightSideBar::winEvent(MSG *msg, long *result)
{
    if (msg->message == WM_NCLBUTTONUP)
     {
      //here can catch the leftmousedown event on titlebar
         qDebug()<<"Title Bar Button Down";
     }
    return false;
}

To copy to clipboard, switch view to plain text mode 

But what should we do to get mouse events on title bar in MAC.
Any help?
