RE: [Plib-devel] puSlider

[Fay J. F C. AAC/W. <joh...@eg...>]

The problem Dave found was that there is an ambiguity between the original
puSlider constructor with "vertical" specified and the new puSlider
constructor with "vertical" left as a default.  If the user creates a new
puSlider object with four integer arguments, the compiler doesn't know which
constructor to call.
 
Another way to fix this might be to change the type of the variable
"vertical".  It only takes the values TRUE and FALSE, so making it "short"
should work.  Unfortunately, this could create confusion if the user creates
a puSlider with four integer numbers:  the computer would know exactly which
constructor it is calling, but the user wouldn't be able to tell easily
without an explicit type casting.  A second alternative would be to make it
"bool", but nothing else in PUI is "bool" and I don't know how portable it
is.

Thanks Blake! 

I got an "ambiguous constructor error" on MSVC so I removed the default
parameter to make it work 

  puSlider ( int minx, int miny, int sz, int vertical = FALSE ) 
  puSlider ( int minx, int miny, int sz, int width, int vertical ) 

Let me know if that is a problem.
