I have some data types defined as enum
in a namespace.
I wanted to use Q_PROPERTY
, that would return the data types...
But I get error:
'staticMetaObject' is not a member of 'blah'
So it seems, if I want to create my own types, and use them in functions that are mentioned in Q_PROPERTY
, they must be inside a class inheriting QObject
and declaring the Q_OBJECT
macro ? Isn't that a lot of overhead ?
is there an alternative ?
Maybe you are searching for Q_GADGET
? It generates metadata for non QObject
derived types. You can have Q_PROPERTY
and Q_INVOKABLE
within a gadget.
And yes, there is quite a lot of overhead, if you don't need QObject
don't use it. It is like 160 bytes to begin with.
