Automatic Scroll in QTextbrowser, how?

[SherifOmran]

Hello guys,

I am writing a program for typing training, and there is a QTextbrowser in which the text is shown ..
What i want to achieve is that, the user gets an automatic scroll when he writes the corresponding line .. ..

@
QTextBrowser *editor;

QPointer <QScrollBar> sb;
sb = ui->editor->verticalScrollBar();

@

I want to know the number of lines in the browser .. or to know the number of steps the QTextbrowser has ..

if i print sb->maximum, it has 0 .. ???

Any Idea
