方法一：可以继承重写一个QSlider
方法二：1.instaneventfiliter(this);slider安装一个事件过滤器
2.在eventfilter(QObject *，QEvent*)中拦截它,很简单吧
例子：
slider=new QSlider(this);
slider->installEventFilter(this);
bool trayIconMenu::eventFilter(QObject *obj, QEvent *event)
{
if(obj==slider)
{
if (event->type()==QEvent::MouseButtonPress) //判断类型
{
QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
if (mouseEvent->button() == Qt::LeftButton) //判断左键
{
int dur = slider->maximum() - slider->minimum();
int pos = slider->minimum() + dur * ((double)mouseEvent->x() / slider->width());
if(pos != slider->sliderPosition())
{
slider->setValue(pos);
}
}
}
}
return QObject::eventFilter(obj,event);
}
okay!即可以实现slider点哪里就到哪里
