I have enums declared within this class, which I have registered with qml via the Q_ENUM macro. print (MyEnumCppNamespace. Working with enum constants. It is not possible to refer to the enumeration type in QML itself; instead, the int or var types can be used when referring to enumeration values from QML code. I just found multiple examples showing the usage of Q_ENUM and Q_ENUMS and looking into the. Each member must have a value, which needs to be constant. @MCQ, necroing the necro'd necro: The syntax presented in the question is not wrong in C. Now we have two strongly typed enums which are accessible from both C++ and QML in one go! As with all classes and types that is exposed to QML, they need to be registered as well: // main. .

It must be placed after the enum declaration in a class that has the Q_OBJECT or the Q_GADGET macro. You can also use QMetaEnum::fromType() to get the QMetaEnum. This requires the exchanged data to be of a type that is recognizable by the engine. An other way, using a QMap : Declare and fill a QMap<QString, QSomeObject::SomeEnum> with the enum values you want in your combo box, then fill your QComboBox with a QStringList of the QMap's keys. . setValue (QString ("Foo"), QVariant::fromValue (value)); The namespace does not have a static QMetaObject to which the Qt MetaObject system can relate the enumeration. The inconvenience with this approach is that there's no type checking at all; any enum value can. The documentation of Q_ENUM gives us the necessary details. For instance, QMetaEnum::fromType () will not work with types declared with Q_ENUMS (). Together with inline namespaces, you can do the following: # ifdef _WIN32 inline # endif namespace audio_win32 { Q_NAMESPACE enum AudioRenderer { Null, OpenAL, XAudio2 }; Q_ENUM_NS (AudioRenderer. toString (); return valueString; } This will generate a QString for an enum declared as: enum class Type {Text, Html, Image, URL};. You need to use Q_ENUM macro, which registers an enum type with the meta-object system. To register a QObject -derived class as an instantiable QML object type, add QML_ELEMENT or QML_NAMED_ELEMENT (<name>) to the class declaration. The enum is only a util class's data, there is no need to. com (mailing list archive)State: Superseded: Headers: showAssuming list1 is a list of strings, then you can simply add them all at once using the addItems method: self.

It is a wrapper around Nuitka, a Python compiler that compiles your Python code to C code, and links with libpython to produce the final executable. The Qt Core module adds these features to C++: a very powerful mechanism for seamless object communication called signals and slots. See the Custom Type Example for code that demonstrates this. Also, to use type T with the QObject::property () API, qRegisterMetaType. The first way is to access MyEnum through QMetaEnum instance of the class. Google has many special features to help you find exactly what you're looking for. Is this your company?
