Subclass KLineEdit (which you`re using instead of QLineWidget, right?)
and reimplement focusInEvent() to call clear().

But why are you trying to do this? In general it seems like a bad
idea. If it`s to implement some kind of instructional message, see
QLineEdit::setPlaceholderText() or KLineEdit::setClickMessage().
