In the QML documentation, "QML Basic Types" has been described or mentioned several times. But to me none appears to be complete. There are 2 important missing pieces of information for each basic type:

1. What is the corresponding Qt class type (or C++ type)?
2. Can it be used as invokable function return type, invokable function argument, signal function argument, property type?

A more complete table like the following would be more helpful to Qt application developers:

=====================================================================
QML type, Description, Qt type, Used as property?, Used in functions?
=====================================================================
point, A point type has x and y attributes, QPoint, No, Yes
———————————————————————————————————————————————————————————————------
...

Do we have this type of table?
