Detailed 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(). +

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. +

int QMetaObject::numSignals ( bool super = FALSE ) const +

+Returns the number of signals for this class. +

If super is TRUE, inherited signals are included. +

int QMetaObject::numSlots ( bool super = FALSE ) const +

+Returns the number of slots for this class. +

If super is TRUE, inherited slots are included. +

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. +

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. +

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. +

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. +
