It seems that indeed we have full knowledge of what is already defined and
thus we should not be calling getCssRule() if it the rule does not yet
exist.
The function void WCssStyleSheet::ruleModified(WCssRule *rule) is probably
not taking into account that a rule is added instead of being modified.
Can you file a bug for this?
The reason why it is so slow, could it be that you have a large amount of
columns in your WTreeView or WTableView classes ?
