Qt编程之实现属性窗口编辑器

类似于这种：

就是右下角这个框，有属性名字和对应的value编辑。

这个Widget是作为一个QDockWidget被添加到QMainWindow中的。QMainWindow必须要有centralWidget才能添加DockWidget。DockWidget是可以浮动于centralWidget周边（上下左右）的一种Widget。QMainWindow中有addDockWiget这相应的函数添加。

而QDockWidget中可以设置相应的Widget，这个Widget（实际上就是属性编辑浏览窗口。）这个Widget实际上不是Qt Native自带的。而是Qt的解决方案中提供的Widget，也就是别人帮你封装做好了Widget，拿来用就可以了。这个Widget就是QtPropertyBrowser

样例代码：

nodeproperty.h  此类继承了QDockWidget
