A range check bug in QwtScaleDiv::setTicks() and QwtScaleDiv::ticks()

[alex_sh]

Hello,

I noticed there are bugs in these functions (qwt_scale_div.cpp) in Qwt SVN:

QwtScaleDiv::setTicks():
if ( type >= 0 || type < NTickTypes )
should be
if ( type >= 0 && type < NTickTypes )

QwtScaleDiv::ticks():
same here.

Cheers and thanks for the awesome library!
Alexander

What does it change on charts?

I don't think it changes anything.
It just introduces a possible out-of-bounds error, if the API user is not careful enough.
