Correct Steve - thanks for pointing that out.

However, there is yet another problem with your design. If you have more
than one slider connected to that callback, there will be only one string
buffer, but there has to be one for each slider. You surely don't want all
sliders to have the same legend.

A possible, but not the best, solution would be to abuse the slider's
string buffer to store the legend string. You could also derive your own
class from puSlider and add a char[] array member.
