[Solved] Always show the end of QTextBrowser

[Fahmy]

Ini my app, I use QTextBrowser to redirect stdout. But the problem is QTextBrowser always show the top of text rather than the end.

So, everytime a new line inserted. I need to scroll to the end to read the latest line. How can I fix this? I've already used movecursor. But still no luck.

@ QByteArray byteTerminal = processObject->readAll();
textTerminal = textTerminal.append(byteTerminal); //textTerminal is a QString.
ui->terminalTextBrowser->moveCursor(QTextCursor::End);
ui->terminalTextBrowser->setText(textTerminal);@

Something like this should do the trick:

@
QScrollBar *sb = ui->terminalTextBrowser()->verticalScrollBar();
sb->setValue(sb->maximum());

Yeah, that ought to work, though I guess there are other methods with scrolling to a cursor or something like that. Anyway, you probably do want to make sure that you only do this auto-scrolling if the scrollbar already was at the end before you add new text. That way, if the user is looking at a section of the log, it won't just scroll away from the section he was looking at because you are adding a new line to the log.

Thanks a lot. It works!

Ps. Just change terminalTextBrowser() to terminalTextBrowser.
