DESCRIPTION
The QMetaProperty class stores meta data about a property.
Property meta data mainly consists of a type(), a name()
and the fact, whether a property is writable(),
designable() or stored().
The functions isSetType(), isEnumType() and enumKeys()
provide further information about a property's type. The
conversion functions keyToValue(), valueToKey(),
keysToValue() and valueToKeys() allow to convert between
the integer representation of an enumeration or set value
and its literal representation.
Actual property values are set and received through
QObject's set and get functions. See
QObject::setProperty() and QObject::property() for
details.
You receive meta property data through an object's meta
QMetaObject::propertyNames() for details.

MEMBER FUNCTION DOCUMENTATION
void QMetaProperty::clearFlags ( uint f )
For internal use only.
bool QMetaProperty::designable () const
Returns whether the property is considered to be
designable or not.
QStrList QMetaProperty::enumKeys () const
Returns the possible enumeration keys if this property is
an enumeration type (or a set type).
See also isEnumType().
bool QMetaProperty::isEnumType () const
Returns whether the property's type is an enumeration
value.
See also isSetType() and enumKeys().
bool QMetaProperty::isSetType () const
Returns whether the property's type is an enumeration
value that is used as set, i.e. the enumeration values can
be or'ed together. A set type is implicitely also an enum
type.
See also isEnumType() and enumKeys().
int QMetaProperty::keyToValue ( const char * key ) const
Converts the enumeration key key to its integer value.
For set types, use keysToValue().
See also valueToKey(), isSetType() and keysToValue().
int QMetaProperty::keysToValue ( const QStrList & keys ) const
Converts the list of keys keys to their combined integer
value.
See also isSetType(), valueToKey() and keysToValue().
const char* QMetaProperty::name () const
Returns the name of the property.
For internal use only.
bool QMetaProperty::stored ( QObject * o ) const
Returns whether the property shall be stored for object o
or not.
bool QMetaProperty::testFlags ( uint f ) const
For internal use only.
const char* QMetaProperty::type () const
Returns the type of the property.
const char* QMetaProperty::valueToKey ( int value ) const
Converts the enumeration value value to its literal key.
For set types, use valueToKeys().
See also valueToKey(), isSetType() and valueToKeys().
QStrList QMetaProperty::valueToKeys ( int value ) const
Converts the set value value to a list of keys.
See also isSetType(), valueToKey() and valueToKeys().
bool QMetaProperty::writable () const
Returns whether the property is writable or not.
See also isValid().
QMetaProperty::QMetaProperty ()
For internal use only.
QMetaProperty::~QMetaProperty ()
For internal use only.
bool QMetaProperty::isValid () const
For internal use only.
