你好，我想问下滑动这块到底怎么实现的，看的一头雾水啊。你有源码吗？

拜托了大哥，我真的是不会啊，现在项目还很急，全靠你了啊。

太谢谢你了，呵呵，不介意加个QQ吧，2606882663，以后方便交流，我做的比较杂，Android，linux，QT都做。

使用的时候
nX = 0;//位置坐标
nY = 0;
defImagePath = "slider_bg.png";//背景及开关图片
actImagePath = "slider.png";
MySliderMenu *pMySlider = new MySliderMenu(pFrameMenu,nX,nY,defImagePath,actImagePath,0);
其中pFrameMenu 是父窗口
效果：
nX = 0;//位置坐标
nY = 0;
defImagePath = "slider_bg.png";//背景及开关图片
actImagePath = "slider.png";
MySliderMenu *pMySlider = new MySliderMenu(pFrameMenu,nX,nY,defImagePath,actImagePath,0);
其中pFrameMenu 是父窗口
效果：

第一个人的代码很有意思，第二个人的总结也挺不错

oldmtn，能不能给我看下运行图啊，我运行了没有反应啊，加下我QQ吧

oldmtn， 你好
为什么我编译的时候总报collect2:ld returned 1 exit status的错误，应该是连接的时候出错了。

谢谢了，我试试看，关键是刚接触QT不久，很多都不会。

我里面主要是加了滑动的的效果，根据手势图片跟着滑动，而且判断滑动距离不到预定距离时松开手指滑块会弹回去，细节比较多

其实就是2张图片，加2个字符串。
你也可以从QWidget派生自己处理，那样比上面的简单多了。
我帖段代码：
#ifndef SWITCHMENU_H
#define SWITCHMENU_H
#include <QWidget>
class SwitchMenu : public QWidget
{
Q_OBJECT
public:
explicit SwitchMenu(QWidget *parent = 0);
protected:
virtual void paintEvent(QPaintEvent *);
virtual void mousePressEvent(QMouseEvent *);
virtual void mouseReleaseEvent(QMouseEvent *);
signals:
public slots:
public:
void initialize(const QString&, const QString&);
private:
QPixmap m_pixmapBk;
QPixmap m_pixmapFore;
bool m_bOn;
bool m_bLBtnDown;
};
#endif // SWITCHMENU_H
#include "switchmenu.h"
#include <QPainter>
#include <QMouseEvent>
SwitchMenu::SwitchMenu(QWidget *parent) :
QWidget(parent)
{
setWindowFlags(Qt::FramelessWindowHint);
m_bOn = false;
m_bLBtnDown = false;
}
void SwitchMenu::paintEvent(QPaintEvent *)
{
QPainter painter(this);
painter.drawPixmap(QPoint(0,0), m_pixmapBk);
QPoint ptFore;
if (m_bOn) {
ptFore = rect().topLeft();
} else {
ptFore = QPoint(this->width() - m_pixmapFore.width(),
this->rect().top());
}
painter.drawPixmap(ptFore, m_pixmapFore);
QRect rcOn;
rcOn.setTopLeft(rect().topLeft());
rcOn.setBottomRight(QPoint(m_pixmapFore.width(), m_pixmapFore.height()));
painter.drawText(rcOn, Qt::AlignCenter, "ON");
QRect rcOff;
rcOff.setTopLeft(QPoint(rect().width() - m_pixmapFore.width(), rect().top()));
rcOff.setBottomRight(rect().bottomRight());
painter.drawText(rcOff, Qt::AlignCenter, "Off");
}
void SwitchMenu::mousePressEvent(QMouseEvent *)
{
m_bLBtnDown = true;
}
void SwitchMenu::mouseReleaseEvent(QMouseEvent *e)
{
if (m_bLBtnDown) {
m_bOn = !m_bOn;
m_bLBtnDown = false;
}
update();
}
void SwitchMenu::initialize(const QString& strImageBk, const QString& strImageFore)
{
m_pixmapBk.load(strImageBk);
m_pixmapFore.load(strImageFore);
int nWidth = m_pixmapBk.width();
int nHeight = m_pixmapBk.height();
setGeometry(0, 0, m_pixmapBk.width(), m_pixmapBk.height());
}
SwitchMenu switchMenu;
switchMenu.initialize(":/res/switchMenu_bk", ":/res/switchMenu_fore");
switchMenu.show();危靖 2013-01-21

我是QT新手，真的不知道怎么做，可以把关键代码贴出来让我看看么，如果有例子的话就更好了，非常感谢你。我的邮箱leisure_wj@163.com

自己写代码，我写过一个，贴图上去，读取触摸位置，移动图片，想怎么滑就怎么滑。
