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

I have done in Pyqt.

self.scrollArea.verticalScrollBar().rangeChanged.connect(self.change_scroll)

--------

@pyqtSlot(int, int)
def change_scroll(self, min, max):
    print("cambio", min, max)
    self.scrollArea.verticalScrollBar().setSliderPosition(max)
