QT如何实现左右滑动的按钮
我要实现这样的功能，就想Iphone一样，实现开关按钮，右滑关闭，左滑打开，这样的功能在QT下怎么实现？
望各位大神赐教。
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。

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
