Does changing the return value of a function break binary compatibility ?? I want to change the QComboBox reference in KToolBar to KComboBox. KComboBox inherits from QComboBox and provides additional functionalities. For details see its documentation. This will make KToolBar consistent since it returns a KLineEdit and not a QLineEdit when a line edit widget is requested. If this does not have any BCI, does anyone object to the change ?? Regards, Dawit A.
