Qt TextBrowser Horizontal Scrollbar

Question

How do I make a horizontal scrollbar appear whenever the application is resized so that every line is as appears? Sometimes, filenames are really long and I don't want to manually resize the form UI.

I have tried setting the scrollbar policy to as needed, but that doesn't do anything. Since the lines are still appearing on the screen.

You have to set the QTextEdit::LineWrapMode to QTextEdit::NoWrap.

ui->textBrowser->setLineWrapColumnOrWidth(QTextEdit::NoWrap); // or just '0'

See class reference for more details.
