Подробное описание

The QMetaMethod class provides meta-data about a member function.

A QMetaMethod has a methodType(), a signature(), a list of parameterTypes() and parameterNames(), a return typeName(), a tag(), and an access() specifier.

Описание типов

enum QMetaMethod::MethodType

Описание функций-членов

Access QMetaMethod::access () const

Returns the access specification of this method (private, protected, or public).

Signals are always protected, meaning that you can only emit them from the class or from a subclass.

See also methodType().

MethodType QMetaMethod::methodType () const

Returns the type of this method (signal, slot, or method).

See also access().

QList< QByteArray> QMetaMethod::parameterNames () const

Returns a list of parameter names.

See also parameterTypes() and signature().

QList< QByteArray> QMetaMethod::parameterTypes () const

Returns a list of parameter types.

See also parameterNames() and signature().

const char * QMetaMethod::signature () const

Returns the signature of this method (e.g., setValue(double)).

See also parameterTypes() and parameterNames().

const char * QMetaMethod::tag () const

Returns the tag associated with this method.

Tags are special macros recognized by moc that make it possible to add extra information about a method. For the moment, moc doesn't support any special tags.

const char * QMetaMethod::typeName () const

Returns the return type of this method, or an empty string if the return type is void.
