Qt属性表QtTreePropertyBrowser的添加（编译方式建议用*.Pro）_qt5.14.2 qttreepropertybrowser

Qt安装的时候选择源码，在安装目录下可以看到QtPropertyBrowser的文件。

利用模板，新建一个Qt Widgets Application 的工程。工程名任取，使用qmake构建

这里建议按默认的名称，要不和本博客后文对不上，得自己一个个对应修改。

在Qt工程的pro文件中加入上图中pri 文件的目录，比如我这里是

include(C:/Qt/Qt5.14.2/5.14.2/Src/qttools/src/shared/qtpropertybrowser/qtpropertybrowser.pri)

pri文件相当于一个库的配置文件，指定源码和头文件的位置，编译方式等。这里的作用是利用pri加载QtTreePropertyBrowser库供我们自己的程序使用。

在ui文件中拖入一个Widget控件，我这里命名为：propertyTree，右键promote to（提升为），Promoted class name：QtTreePropertyBrowser

 再在界面上添加两个按钮，一个作用是清除属性表，一个是重置属性表为初始值。
