Qt浅谈之三十六仿360设置中心

一、简介

        模仿360设置中心面板的功能：左侧导航使用QTreeWidget，右侧的显示区域使用QScrollArea控件；主要使用垂直滚动条的valueChanged事件和QTreeWidget的itemClicked事件；通过调用QWidget的visibleRegion().isEmpty() 判断QScrollArea中滑动过的区域，通过垂直滚动条的setSliderPosition方法设置QScrollArea的新的区域，通过QTreeWidget的topLevelItemCount()和topLevelItem(index)判断顶层的item，并通过QTreeWidget的setCurrentItem(item)来设置切换各个选项。

二、详解

三、总结

（1）上述仅实现了界面的功能，数据功能暂不涉及。最后两项的界面未完成，基本是重复前面的内容，可执行程序已上传到csdn：http://download.csdn.net/detail/taiyang1987912/9364501。
（2）有些界面的背景和样式还需要调整的，部分样式无法调整可以继承QWidget重新书写一个完整的控件（需要熟悉Qt）。
（3）若有建议，请留言，在此先感谢！
