And while does seem odd, I will not dismiss the idea without giving it

Some of this may depend upon what your toolkit expects. For example, in Qt,
the QSlider widget has *two* signals that are emitted when a slider position
changes. One ('valueChanged(int)') is emitted whenever the position changes,
for whatever reason, while the other ('sliderMoved(int)') is emitted only
when the change was due to the *user* moving the control --i.e. not when
updated by the program itself. Choosing the correct one to use in a given
context is important in order to avoid the kind of problems Fons has
mentioned.
Cheers!
