Hi again, I am trying to work again on my project http://shift.freezope.org/konq_rellinks that I let with no life since June. David Faure told me to use event filtering to solve my problem http://lists.kde.org/?l=kfm-devel&m=105467616218760&w=2 but I don't know how to do this. In http://www.kdevelop.org/doc/kde_libref/index-4.html there are example but I don't know how to catch a focus event of the KHTMLPart and to react on it by updating my toolbar. Please help me ! Thanks, Franck. PS : Is it http://developer.kde.org/documentation/library/cvs-api/kparts/html/classKParts_1_1GUIActivateEvent.html that I should use ?
