[Percy Camilo Triveño Aucahuasi]

Hi all, when I change the color style of my desktop, then the simbols in
KSudoku dissapears, check this screenshots:

Default look:

This patch solved that problem. This is the screenshot with the patch:

In the patch I'm using this lines to obtain the base color of the window:

//********************************
KColorScheme systemColorScheme(QPalette::Active);
QColor baseWndColor =
systemColorScheme.background(KColorScheme::NormalBackground).color();
int luminance = 0.2126*baseWndColor.red() + 0.7152*baseWndColor.green() +
0.0722*baseWndColor.blue();
if (luminance > (255 / 2.0))
// set the color font/brush to black
else
// set the color font/brush to white
//********************************

Is that ok? or there is a better way?

If it's ok ... may I commit? ; )

Cheers,
Percy
