Ich hab hier ne fremde CTitleTip Klasse (die glaub ich irgendwo frei
verfügbar ist im web) und möchte den Text im Titletip Fenster
markierbar und kopierbar machen.

Aber ich hab keinen Schimmer wie man da macht, weiß jemand
von Euch wie das geht ?

Falls es hilfreich ist hab ich mal die dafür wahrscheinlich
wichtigstens Methoden angehängt. Eventuell reicht es schon
irgendwo spezielle Flags zu setzen um den Text markierbar
zu machen ?

Danke für jede Hilfe !
