Realize QPlainTextEdit PageUp/Down in code?

[Mr Pang]

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); });
