Detailed Description
The QMetaObject class contains meta information about Qt objects.
The Meta Object System in Qt is responsible for the signal/slot
mechanism for communication between objects, runtime type
information and the property system. All meta information in Qt is
kept in a singla instance of QMetaObject per class.
In general, you will not have to use this class directly in any
application program. Most of the class members and functions are
internal, do not use them .
Some functions, however, are marked as public API and may make sense
for certain "meta" applications such as scripting engines or GUI
builders:
Member Function Documentation
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
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().
bool QMetaObject::inherits ( const char * clname ) const
Returns TRUE if this class inherits clname within the meta
object inheritance chain.
(A class is considered to inherit itself.).
int QMetaObject::numClassInfo ( bool super = FALSE ) const
Returns the number of class information available for this class.
If super is TRUE, inherited class information is included.
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 ( const char * name, bool super = FALSE ) const
Returns the property meta data for the property with name name
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 properties for this class.
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 signals for this class.
If super is TRUE, inherited signals are included.
See also: signal().
QStrList QMetaObject::slotNames ( bool super = FALSE ) const
Returns a list with the names of all slots for this class.
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 super class, or 0 if there is no super
class in the QObject hierachy.
