Deprecated methods
With time, there are more and more deprecated methods used:
bool QVariant::operator<=(const QVariant&) const
-void KWindowEffects::slideWindow(WId, KWindowEffects::SlideFromLocation, int)
-quint32 KWayland::Client::PlasmaWindow::internalId() const
-int qrand()
and many many others.
What do you think of updating them?
