.SH DESCRIPTION
The TQMetaProperty 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 TQObject's set and get functions. See TQObject::setProperty() and TQObject::property() for details.
.PP
You receive meta property data through an object's meta object. See TQMetaObject::property() and TQMetaObject::propertyNames() for details.
.PP
See also Object Model.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "bool TQMetaProperty::designable ( TQObject * 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 "TQStrList TQMetaProperty::enumKeys () const"
Returns the possible enumeration keys if this property is an enumeration type (or a set type).
.PP
See also isEnumType().
.SH "bool TQMetaProperty::isEnumType () const"
Returns TRUE if the property's type is an enumeration value; otherwise returns FALSE.
.PP
See also isSetType() and enumKeys().
.SH "bool TQMetaProperty::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 TQMetaProperty::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 TQMetaProperty::keysToValue ( const TQStrList & 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 * TQMetaProperty::name () const"
Returns the name of the property.
.SH "bool TQMetaProperty::reset ( TQObject * 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 TQMetaProperty::scriptable ( TQObject * 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 TQMetaProperty::stored ( TQObject * 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 * TQMetaProperty::type () const"
Returns the type of the property.
.SH "const char * TQMetaProperty::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 "TQStrList TQMetaProperty::valueToKeys ( int value ) const"
Converts the set value \fIvalue\fR to a list of keys.
.PP
See also isSetType() and valueToKey().
.SH "bool TQMetaProperty::writable () const"
Returns TRUE if the property is writable; otherwise returns FALSE.
.PP
