QMetaProperty::read: Unable to handle unregistered datatype 'QList<char>' for propert

[TheIndependentAquarius]

The problem is that char is NOT "my" type. It is a key word in C and C++.
I wrote this:

Q_PROPERTY (QList<char> pointType READ pointType WRITE setPointType NOTIFY pointTypeChanged)

Q_PROPERTY (QList<char> pointType READ pointType WRITE setPointType NOTIFY pointTypeChanged)

To copy to clipboard, switch view to plain text mode 

and I get that error when I access it in QML. Yes, I have used qmlRegisterType for registering my class in main.cpp.
I have used other objects too like int and QList, but the error occurs only for char.

When int works why doesn't char work?

The type "QList of char" is not known to Qt's type system.

Simply

Q_DECLARE_METATYPE(QList<char>)

Q_DECLARE_METATYPE(QList<char>)

To copy to clipboard, switch view to plain text mode 

somewhere, e.g. the header of the class using that property.

Yes, that is obvious but I'd like to know the reasons. When int is registered why isn't char? They have QChar then why not QInt?

[anda_skoa]

Most likely because QList<int> was needed somewhere while QList<char> was not.

QChar is not a Qt type for char as in the numerical value type, but to hold a single unicode text character, including conversion functions, etc. It could also be named QLetter.
