QSlider 解决点击不能到该位置问题

方法一：可以继承重写一个QSlider方法二(推荐)： 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 http://blog.csdn.net/what951006/article/details/51507801
