DESCRIPTION
       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().

       See also moc (Meta Object Compiler) and Object Model.

MEMBER FUNCTION DOCUMENTATION
const QClassInfo * QMetaObject::classInfo ( int index, bool super = FALSE ) const
       Returns the class information with index index or 0 if no such information exists.

       If super is TRUE, inherited class information is included.

const char * QMetaObject::classInfo ( const char * name, bool super = FALSE ) const
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Returns the class information with name name or 0 if no such information exists.

       If super is TRUE, inherited class information is included.

const char * QMetaObject::className () const
       Returns the class name.

       See also QObject::className() and superClassName().

int QMetaObject::findProperty ( const char * name, bool super = FALSE ) const
       Returns the index for the property with name name or -1 if no such property exists.

       If super is TRUE, inherited properties are included.

       See also property() and propertyNames().

bool QMetaObject::inherits ( const char * clname ) const
       Returns TRUE if this class inherits clname within the meta object inheritance chain;
       otherwise returns FALSE.

       (A class is considered to inherit itself.)

int QMetaObject::numClassInfo ( bool super = FALSE ) const
       Returns the number of items of class information available for this class.

       If super is TRUE, inherited class information is included.

int QMetaObject::numProperties ( bool super = FALSE ) const
       Returns the number of properties for this class.

       If super is TRUE, inherited properties are included.

       See also propertyNames().

int QMetaObject::numSignals ( bool super = FALSE ) const
       Returns the number of signals for this class.

       If super is TRUE, inherited signals are included.

       See also signalNames().

int QMetaObject::numSlots ( bool super = FALSE ) const
       Returns the number of slots for this class.

       If super is TRUE, inherited slots are included.

       See also slotNames().

const QMetaProperty * QMetaObject::property ( int index, bool super = FALSE ) const
       Returns the property meta data for the property at index index or 0 if no such property
       exists.

       If super is TRUE, inherited properties are included.

       See also propertyNames().

QStrList QMetaObject::propertyNames ( bool super = FALSE ) const
       Returns a list with the names of all this class's properties.

       If super is TRUE, inherited properties are included.

       See also property().

QStrList QMetaObject::signalNames ( bool super = FALSE ) const
       Returns a list with the names of all this class's signals.

       If super is TRUE, inherited signals are included.

QStrList QMetaObject::slotNames ( bool super = FALSE ) const
       Returns a list with the names of all this class's slots.

       If super is TRUE, inherited slots are included.

       See also numSlots().

QMetaObject * QMetaObject::superClass () const
       Returns the meta object of the super class or 0 if there is no such object.

const char * QMetaObject::superClassName () const
       Returns the class name of the superclass or 0 if there is no superclass in the QObject
       hierachy.

       See also className().
