    Hi, everyOne!
    I have 2 PushButtons and a QPlainTextEdit. When clicking the 2 buttons, I want the QPlainTextEdit to pageup/down.
    Is it possible?

      You can trigger a page up/down action like this:

      connect(buttonUp, &QPushButton::clicked,
              [=]{ textEdit->verticalScrollBar()->triggerAction(QAbstractSlider::SliderPageStepSub); });
      connect(buttonDown, &QPushButton::clicked,
              [=]{ textEdit->verticalScrollBar()->triggerAction(QAbstractSlider::SliderPageStepAdd); });
