QMetaEnum用来代表枚举信息,内部也是访问moc文件。从moc文件中得到对应值

需要在头文件中声明 Q_ENUM,如下红框部分

moc中qt_meta_stringdata_XTest变为：

qt_meta_data_XTest变为

static const uint qt_meta_data_XTest[] = {

// content:

8, // revision

0, // classname

1, 14, // classinfo

5, 16, // methods

1, 59, // properties

1, 63, // enums/sets

0, 0, // constructors

0, // flags
