问题(Question)：

我目前用了QSlier
我想请问有没有办法写额外两个button去控制pageup and down呢(图片的红框处)
(因为Slier的卷轴我之后要隐藏它)
我目前的写法如下，但这样要自己去算每个widget的间距 非常麻烦
请问有没有更好的办法呢
connect(btnArrowRight, SIGNAL(released()), this, SLOT(moveControllerBox()));
//连结button
void myclass::moveControllerBox() {
QPushButton *btn = qobject_cast<QPushButton *>(sender());
QScrollBar *horizontalScrollBar = listWidget->horizontalScrollBar();
int value = listWidget->horizontalScrollBar()->value();
int movePosition = 0;
if (btn->objectName() == "ArrowLeft") {
if (value - 100 < 0) movePosition = 0;
else movePosition = value - 100;
}
else if (btn->objectName() == "ArrowRight") {
if (value + 100 > 1020) movePosition = 1020;
else movePosition = value + 100;
}
horizontalScrollBar->setSliderPosition(movePosition);
}
