Member Function Documentation
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.
