I'm not sure if the API exposes the internal widgets but the text content is of course just a simple widget of which you can only see a small part. The QTextEdit just builds itself from these parts (text editor, scroll bars and a nice frame to wrap those three together). Check the slots of the scroll bars to see how they get the visible/total size of the scrolled area. These should be the number you're looking for. Regards, -- Aaron "Optimizer" Digulla a.k.a.
