It can't really be done in a one line command, you will have to create a procedure to execute the method.

ON SELECTION BAR 1 of mypopup myBar1Procedure

Is the method to be called is not dependent on the current state of properties in the object:

procedure myBar1Procedure
  with newobject("myclass", "myclasslib")
    .myMethod()
  endwith
endproc

Otherwise:

procedure myBar1Procedure

  if vartype( oExternalReference ) != 'O'
    * either throw an error or initialize the oExternalReference at this point
  endif
  oExternalReference.myMethod()
endproc
