Description Milan Krivda 2008-03-16 11:45:27 UTC

Version:            (using KDE 4.0.2)
Installed from:    Gentoo Packages
OS:                Linux

If i open configure desktop dialog and try to pickup color, color picker is returning bad (i think randomized) color values. If i take color from same place three times, colorpicker return three times different colors. Color picking is working right from other qt4, kde4 applications.

SVN commit 820607 by pino:

When we are compibiling for X11, and Xutil.h was found, use the Xlib API to get the color value of a pixel of the screen. In all the other cases, use the "classic" Qt code.
This workarounds a bug in either Qt or X (Qt, probably), but should be fine for now.

interesting ... this only fixes the kolourpicker plasmoid, of course; i think something similar will need to be done to KColorDialog::grabColor for the desktop settings dialog which still doesn't work. i'm testing now. thanks for the patch, Pino; sad we have to go under Qt for this =/
