How can we get current cursor position in any part of window from the child class.

[pratik041]

we have a class

class custom::public QObject
                                         {
                                            Q_OBJECT
                                            public:
                                                 custom(QWidget *parent)
                                                  {
 
                                                     }
                                                  bool event (QEvent *e)
                                                {
                                                  //get cursor position.
 
                                                   }
                                               };

class custom::public QObject
                                         {
                                            Q_OBJECT
                                            public:
                                                 custom(QWidget *parent)
                                                  {
                                                     
                                                     }
                                                  bool event (QEvent *e)
                                                {
                                                  //get cursor position.
 
                                                   }
                                               };

suppose we have the above child class. Inside child class event how can we get cursor position irrespective of whether the cursor is on the parent or on the other child of same parent. I have inherited from QObject because i dont want to create any widget in this class just i want to know cursor position to handle other objects.
