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. +.PP + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/qmetaproperty.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
