.SH DESCRIPTION
The QMetaObject class contains meta information about Qt objects.
.PP
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 single instance of QMetaObject per class.
.PP
In general, you will not have to use this class directly in any application program. Most of the class members and functions are internal, \fB do not use them \fR.
.PP
Some functions, however, are marked as public API and may make sense for certain "meta" applications such as scripting engines or GUI builders:
.TP
className() to get the name of a class.
.TP
superClassName() to get the name of the superclass.
.TP
inherits(), the function called by QObject::inherits().
.TP
superClass() to access the meta object of the superclass.
.TP
numSlots(), numSignals(), slotNames() and signalNames() to get information about a classes signals and slots.
.TP
property() and propertyNames() to receive information about a classes properties.
.TP
classInfo() and numClassInfo() to access additional class information.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QClassInfo* QMetaObject::classInfo ( int index, bool super = FALSE ) const"
Returns the class information with index \fIindex\fR or 0 if no such information exists.
.PP
If \fIsuper\fR is TRUE, inherited class information is included.
.SH "const char* QMetaObject::classInfo ( const char * name, bool super = FALSE ) const"
Returns the class information with name \fIname\fR or 0 if no such information exists.
.PP
If \fIsuper\fR is TRUE, inherited class information is included.
.SH "const char * QMetaObject::className () const"
Returns the class name.
.PP
See also QObject::className() and superClassName().
.SH "bool QMetaObject::inherits ( const char * clname ) const"
Returns TRUE if this class inherits \fIclname\fR within the meta object inheritance chain.
.PP
(A class is considered to inherit itself.).
.SH "int QMetaObject::numClassInfo ( bool super = FALSE ) const"
Returns the number of class information available for this class.
.PP
If \fIsuper\fR is TRUE, inherited class information is included.
.SH "int QMetaObject::numSignals ( bool super = FALSE ) const"
Returns the number of signals for this class.
.PP
If \fIsuper\fR is TRUE, inherited signals are included.
.PP
See also signalNames().
.SH "int QMetaObject::numSlots ( bool super = FALSE ) const"
Returns the number of slots for this class.
.PP
If \fIsuper\fR is TRUE, inherited slots are included.
.PP
See also slotNames().
.SH "const QMetaProperty* QMetaObject::property ( const char * name, bool super = FALSE ) const"
Returns the property meta data for the property with name \fIname\fR or 0 if no such property exists.
.PP
If \fIsuper\fR is TRUE, inherited properties are included.
.PP
See also propertyNames().
.SH "QStrList QMetaObject::propertyNames ( bool super = FALSE ) const"
Returns a list with the names of all properties for this class.
.PP
If \fIsuper\fR is TRUE, inherited properties are included.
.PP
See also property().
.SH "QStrList QMetaObject::signalNames ( bool super = FALSE ) const"
Returns a list with the names of all signals for this class.
.PP
If \fIsuper\fR is TRUE, inherited signals are included.
.PP
See also signal().
.SH "QStrList QMetaObject::slotNames ( bool super = FALSE ) const"
Returns a list with the names of all slots for this class.
.PP
If \fIsuper\fR is TRUE, inherited slots are included.
.PP
See also numSlots().
.SH "QMetaObject * QMetaObject::superClass () const"
Returns the meta object of the super class or 0, if there is no such object.
.SH "const char * QMetaObject::superClassName () const"
Returns the class name of the super class, or 0 if there is no super class in the QObject hierarchy.
.PP
See also className().
