◆ absoluteSignalCount()

int QMetaObjectPrivate::absoluteSignalCount ( const QMetaObject * m )

static

Since: 5.0

Returns the number of signals for the class m, including the signals for the base class.

Similar to QMetaObject::methodCount(), but non-signal methods are excluded.

Returns true if the signal and method arguments are compatible; otherwise returns false.

Same as the QMetaObject::connect, but signal_index must be the result of QObjectPrivate::signalIndex

method_index is relative to the rmeta metaobject, if rmeta is \nullptr, then it is absolute index

the QObjectPrivate::Connection* has a refcount of 2, so it must be passed to a QMetaObject::Connection

◆ memberIndexes()

void QMetaObjectPrivate::memberIndexes	(	const QObject *	obj,

static

This helper function calculates signal and method index for the given member in the specified class.

\list

If member.mobj is \nullptr then both signalIndex and methodIndex are set to -1.

If specified member is not a member of obj instance class (or one of its parent classes) then both signalIndex and methodIndex are set to -1. \endlist

This function is used by QObject::connect and QObject::disconnect which are working with QMetaMethod.

signalIndex is set to the signal index of member. If the member specified is not signal this variable is set to -1.

methodIndex is set to the method index of the member. If the member is not a method of the object specified by the obj argument this variable is set to -1.
