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
2, // signalCount
// classinfo: key, value
1, 2,
// signals: name, argc, parameters, tag, flags

QMetaType::Void, 0x80000000 | 11, 12,
QMetaType::Void, 0x80000000 | 14, 15,
