Value ranges in QColor

[Tuggi]

Hi all,

I want to enhance my qt5.natvis file for VS2013. I added a section as follows:

<Type Name="QColor">
   <DisplayString Condition="QColor::Rgb  == cspec">{{ r={(ct.argb.red   * 255) / 65535} g={(ct.argb.green      * 255) / 65535} b={(ct.argb.blue      * 255) / 65535} }}</DisplayString>
   <DisplayString Condition="QColor::Hsv  == cspec">{{ h={(ct.ahsv.hue   * 359) / 65535} s={(ct.ahsv.saturation * 255) / 65535} v={(ct.ahsv.value     * 255) / 65535} }}</DisplayString>
   <DisplayString Condition="QColor::Cmyk == cspec">{{ c={(ct.acmyk.cyan * 255) / 65535} m={(ct.acmyk.magenta   * 255) / 65535} y={(ct.acmyk.yellow   * 255) / 65535} k={(ct.acmyk.black * 255) / 65535} }}</DisplayString>
   <DisplayString Condition="QColor::Hsl  == cspec">{{ h={(ct.ahsl.hue   * 359) / 65535} s={(ct.ahsl.saturation * 255) / 65535} l={(ct.ahsl.lightness * 255) / 65535} }}</DisplayString>   
</Type>

I want my debugger to show the color values within the valid range ( typ. [0..255] ). But as QColor stores the values in ushort format, I guess that the value ist scaled; i.e. 65535 in QColor stands for 255 in RGB code.
So I want to know, if my assumption is correct.
Thank's very much
