KGlobalSettings: EffectFadeMenu and EffectFadeTooltip obsolete?

[Peter Penz]

Hi,

when turning on the global effects "EffectFadeMenu" and "EffectFadeTooltip" in 
KGlobalSettings::Private::propagateSettings() 
(kdelibs/kdeui/kernel/kglobalsettings.cpp) by:

    b = cg.readEntry("EffectFadeMenu", false);
    QApplication::setEffectEnabled( Qt::UI_FadeMenu, b);
    ...
    b = cg.readEntry("EffectFadeTooltip", false);
    QApplication::setEffectEnabled( Qt::UI_FadeTooltip, b);

there are some side effects for drag and drop in KDE (see 
http://bugs.kde.org/show_bug.cgi?id=157630 for details - other applications 
are affected too, not only Dolphin).

I've already submitted a bug report to Qt some time ago 
(http://trolltech.com/developer/task-
tracker/index_html?method=entry&id=207192), but I was wondering whether those 
effects are obsolete in KDE 4 and hence should be ignored.

It seems there is no GUI available anymore to turn on/off those settings, so 
only users who migrated the settings from KDE 3 seems to be affected.

Would it be OK to submit a patch for KGlobalSettings to ignore those old 
settings? Or do I miss here something?

Thanks,
Peter
