Hi Stanislav,

One possible solution could be to use :

gVirtualX->QueryPointer(fId, wdum1, wdum2, xroot, yroot, x, y, state);

If you look at TVirtualX::QueryPointer :

//______________________________________________________________________________

void TVirtualX::QueryPointer(Window_t /*id*/, Window_t &rootw, Window_t &childw,

                             Int_t &root_x, Int_t &root_y, Int_t &win_x,
                             Int_t &win_y, UInt_t &mask)

{

   // Returns the root window the pointer is logically on and the pointer
   // coordinates relative to the root window's origin.
   //
   // id             - specifies the window
   // rotw           - the root window that the pointer is in
   // childw         - the child window that the pointer is located in, 

if any

   // root_x, root_y - the pointer coordinates relative to the root window's
   //                  origin
   // win_x, win_y   - the pointer coordinates relative to the specified
   //                  window "id"
   // mask           - the current state of the modifier keys and pointer
   //                  buttons

Cheers,
Bertrand.
