Descripción detallada

The QMetaObject class contains meta information about Qt objects.

The Meta Object System in Qt is responsible for the signals and slots inter-object communication mechanism, runtime type information and the property system. All meta information in Qt is kept in a single instance of QMetaObject per class.

This class is not normally required for application programming. But if you write meta applications, such as scripting engines or GUI builders, you might find these functions useful: className() to get the name of a class. superClassName() to get the name of the superclass. inherits(), the function called by QObject::inherits(). superClass() to access the superclass's meta object. numSlots(), numSignals(), slotNames(), and signalNames() to get information about a class's signals and slots. property() and propertyNames() to obtain information about a class's properties.

Classes may have a list of name-value pairs of class information. The number of pairs is returned by numClassInfo(), and values are returned by classInfo().
