Question

How to program scrollbar to jump to bottom/top in case of change in QPlainTextEdit or QTextEdit area? It looks like it doesn\'t have any controlling function.

Answer 1

When a text edit control is resized, QWidget::resizeEvent is called. You just have to override this function in your subclass, and call verticalScrollBar -> setValue (verticalScrollBar -> minimum()) (or maximum()).
