Macro Definition Documentation

QTMVVM_INJECT

#define QTMVVM_INJECT	(		classType,
			name
	)

Value:

static inline QByteArray __qtmvvm_inject_##name() { \
        return QtMvvm::__helpertypes::inject_iid<classType>(); \
    } \
    Q_PROPERTY(QByteArray __qtmvvm_inject_##name READ __qtmvvm_inject_##name STORED false SCRIPTABLE false DESIGNABLE false CONSTANT FINAL)

Mark a property for injection.

Parameters

classType	The type of the property to be injected
name	The name of the property to be injected

This macro creates an additional property that is detected by the QtMvvm::ServiceRegistry and contains the information needed to inject the property automatically. For more details on the property injection, see QtMvvm::ServiceRegistry

Sample code for usage:

class MyClass : public QObject
{
    Q_OBJECT

    Q_PROPERTY(IService* service READ service WRITE setService)
    QTMVVM_INJECT(IService*, service)

public:
    //...
}

Note

All properties that make use of interfaces must register the interfaces via QtMvvm::registerInterfaceConverter

QTMVVM_INJECT_PROP

#define QTMVVM_INJECT_PROP	(		type,
			name,
			member
	)

Value:

Q_PROPERTY(type name MEMBER member) \
    QTMVVM_INJECT(type, name)

Create a for injection marked property based on a member.

Parameters

type	The type of the property to be created
name	The name of the property to be created
member	The name of the member variable to use for the property

This macro is a shortcut for QTMVVM_INJECT to create a property and mark it for injection in one step. The property is created by using a member variable. This means it will have no public member functions to access the property, only the property accessors itself.

Sample code for usage:

class MyClass : public QObject
{
    Q_OBJECT

    QTMVVM_INJECT_PROP(IService*, service, _service)

public:
    //...

private:
    IService* _service;
}

Note

All properties that make use of interfaces must register the interfaces via QtMvvm::registerInterfaceConverter
