To include the definitions of the module's classes, use the following directive: \code #include \endcode To link against the module, add this line to your \l qmake \c .pro file: \code QT += declarative \endcode For more information on the Qt Declarative module, see the \l{Qt Quick} documentation. */ /*! \macro QML_DECLARE_TYPE() \relates QDeclarativeEngine Equivalent to \c Q_DECLARE_METATYPE(TYPE *) and \c Q_DECLARE_METATYPE(QDeclarativeListProperty) #include to use this macro. */ /*! \macro QML_DECLARE_TYPEINFO(Type,Flags) \relates QDeclarativeEngine Declares additional properties of the given \a Type as described by the specified \a Flags. Current the only supported type info is \c QML_HAS_ATTACHED_PROPERTIES which declares that the \a Type supports \l {Attached Properties}. #include to use this macro. */ /*! \fn int qmlRegisterType(const char *uri, int versionMajor, int versionMinor, const char *qmlName) \relates QDeclarativeEngine This template function registers the C++ type in the QML system with the name \a qmlName, in the library imported from \a uri having the version number composed from \a versionMajor and \a versionMinor. Returns the QML type id. There are two forms of this template function: \code template int qmlRegisterType(const char *uri, int versionMajor, int versionMinor, const char *qmlName); template int qmlRegisterType(const char *uri, int versionMajor, int versionMinor, const char *qmlName); \endcode The former is the standard form which registers the type \e T as a new type. The latter allows a particular revision of a class to be registered in a specified version (see \l {QML Type Versioning}). For example, this registers a C++ class \c MySliderItem as a QML type named \c Slider for version 1.0 of a \l{QML Modules}{module} called "com.mycompany.qmlcomponents": \code #include ... qmlRegisterType("com.mycompany.qmlcomponents", 1, 0, "Slider"); \endcode Once this is registered, the type can be used in QML by importing the specified module name and version number: \qml import com.mycompany.qmlcomponents 1.0 Slider { // ... } \endqml Note that it's perfectly reasonable for a library to register types to older versions than the actual version of the library. Indeed, it is normal for the new library to allow QML written to previous versions to continue to work, even if more advanced versions of some of its types are available. */ /*! \fn int qmlRegisterUncreatableType(const char *uri, int versionMajor, int versionMinor, const char *qmlName, const QString& message) \relates QDeclarativeEngine This template function registers the C++ type in the QML system with the name \a qmlName, in the library imported from \a uri having the version number composed from \a versionMajor and \a versionMinor. While the type has a name and a type, it cannot be created, and the given error \a message will result if creation is attempted. This is useful where the type is only intended for providing attached properties or enum values. Returns the QML type id. #include to use this function. \sa qmlRegisterTypeNotAvailable() */ /*! \fn int qmlRegisterTypeNotAvailable(const char *uri, int versionMajor, int versionMinor, const char *qmlName, const QString& message) \relates QDeclarativeEngine This function registers a type in the QML system with the name \a qmlName, in the library imported from \a uri having the version number composed from \a versionMajor and \a versionMinor, but any attempt to instantiate the type will produce the given error \a message. Normally, the types exported by a module should be fixed. However, if a C++ type is not available, you should at least "reserve" the QML type name, and give the user of your module a meaningful error message. Returns the QML type id. Example: \code #ifdef NO_GAMES_ALLOWED qmlRegisterTypeNotAvailable("MinehuntCore", 0, 1, "Game", "Get back to work, slacker!"); #else qmlRegisterType("MinehuntCore", 0, 1, "Game"); #endif \endcode This will cause any QML which uses this module and attempts to use the type to produce an error message: \code fun.qml: Get back to work, slacker! Game { ^ \endcode Without this, a generic "Game is not a type" message would be given. #include to use this function. \sa qmlRegisterUncreatableType() */ /*! \fn int qmlRegisterType() \relates QDeclarativeEngine \overload This template function registers the C++ type in the QML system. Instances of this type cannot be created from the QML system. #include to use this function. Returns the QML type id. */ /*! \fn int qmlRegisterInterface(const char *typeName) \relates QDeclarativeEngine This template function registers the C++ type in the QML system under the name \a typeName. #include to use this function. Returns the QML type id. */
