ich glaub zwar das einige genervt sind von der Frage die ich hier stelle aber ich versuch es doch einmal
Ich versuche unter Windows mit dem Microsoft VC 2005 Studio eine Aplikation zu erstellen. Ich hoffe das ich die Qt4 Bibliotheken richtig eingebunden zu haben, jedenfalls läßt es sich compelieren und starten. Mein Problem ist jetzt das ich ein Menü erstellen möchte (oder habe) und wenn der Anwender auf ein Menüunterpunkt clicked möcht ich das eine Procedur aufgerufen wird. Das Problem ist nur das ich in der Console immer den Hinweiß bekomme das die slots nicht bekannt sind.
Vielleicht kann mir ja jemand einen Tip geben wo der Fehler ist.
