+.SH DESCRIPTION
+The QMetaProperty class stores meta data about a property.
+.PP
+Property meta data includes type(), name(), and whether a property is writable(), designable() and stored().
+.PP
+The functions isSetType(), isEnumType() and enumKeys() provide further information about a property's type. The conversion functions keyToValue(), valueToKey(), keysToValue() and valueToKeys() allow conversion between the integer representation of an enumeration or set value and its literal representation.
+.PP
+Actual property values are set and received through QObject's set and get functions. See QObject::setProperty() and QObject::property() for details.
+.PP
+You receive meta property data through an object's meta object. See QMetaObject::property() and QMetaObject::propertyNames() for details.
+.PP
+See also Object Model.
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "bool QMetaProperty::designable ( QObject * o = 0 ) const"
+Returns TRUE if the property is designable for object \fIo\fR; otherwise returns FALSE.
+.PP
+If no object \fIo\fR is given, the function returns a static approximation.
+.SH "QStrList QMetaProperty::enumKeys () const"
+Returns the possible enumeration keys if this property is an enumeration type (or a set type).
+.PP
+See also isEnumType().
+.SH "bool QMetaProperty::isEnumType () const"
+Returns TRUE if the property's type is an enumeration value; otherwise returns FALSE.
+.PP
+See also isSetType() and enumKeys().
+.SH "bool QMetaProperty::isSetType () const"
+Returns TRUE if the property's type is an enumeration value that is used as set, i.e. if the enumeration values can be OR-ed together; otherwise returns FALSE. A set type is implicitly also an enum type.
+.PP
+See also isEnumType() and enumKeys().
+.SH "int QMetaProperty::keyToValue ( const char * key ) const"
+Converts the enumeration key \fIkey\fR to its integer value.
+.PP
+For set types, use keysToValue().
+.PP
+See also valueToKey(), isSetType(), and keysToValue().
+.SH "int QMetaProperty::keysToValue ( const QStrList & keys ) const"
+Converts the list of keys \fIkeys\fR to their combined (OR-ed) integer value.
+.PP
+See also isSetType() and valueToKey().
+.SH "const char * QMetaProperty::name () const"
+Returns the name of the property.
+.SH "bool QMetaProperty::reset ( QObject * o ) const"
+Tries to reset the property for object \fIo\fR with a reset method. On success, returns TRUE; otherwise returns FALSE.
+.PP
+Reset methods are optional, usually only a few properties support them.
+.SH "bool QMetaProperty::scriptable ( QObject * o = 0 ) const"
+Returns TRUE if the property is scriptable for object \fIo\fR; otherwise returns FALSE.
+.PP
+If no object \fIo\fR is given, the function returns a static approximation.
+.SH "bool QMetaProperty::stored ( QObject * o = 0 ) const"
+Returns TRUE if the property shall be stored for object \fIo\fR; otherwise returns FALSE.
+.PP
+If no object \fIo\fR is given, the function returns a static approximation.
+.SH "const char * QMetaProperty::type () const"
+Returns the type of the property.
+.SH "const char * QMetaProperty::valueToKey ( int value ) const"
+Converts the enumeration value \fIvalue\fR to its literal key.
+.PP
+For set types, use valueToKeys().
+.PP
+See also isSetType() and valueToKeys().
+.SH "QStrList QMetaProperty::valueToKeys ( int value ) const"
+Converts the set value \fIvalue\fR to a list of keys.
+.PP
+See also isSetType() and valueToKey().
+.SH "bool QMetaProperty::writable () const"
+Returns TRUE if the property is writable; otherwise returns FALSE.
