< p > The TQMetaProperty class stores meta data about a property.
< p >
< p > Property meta data includes < a href = "#type" > type< / a > (), < a href = "#name" > name< / a > (), and whether a property
is < a href = "#writable" > writable< / a > (), < a href = "#designable" > designable< / a > () and < a href = "#stored" > stored< / a > ().
< p > The functions < a href = "#isSetType" > isSetType< / a > (), < a href = "#isEnumType" > isEnumType< / a > () and < a href = "#enumKeys" > enumKeys< / a > () provide
further information about a property's type. The conversion
functions < a href = "#keyToValue" > keyToValue< / a > (), < a href = "#valueToKey" > valueToKey< / a > (), < a href = "#keysToValue" > keysToValue< / a > () and
< a href = "#valueToKeys" > valueToKeys< / a > () allow conversion between the integer representation
of an enumeration or set value and its literal representation.
< p > Actual property values are set and received through < a href = "tqobject.html" > TQObject< / a > 's set
and get functions. See < a href = "tqobject.html#setProperty" > TQObject::setProperty< / a > () and
< a href = "tqobject.html#property" > TQObject::property< / a > () for details.
< p > You receive meta property data through an object's < a href = "metaobjects.html#meta-object" > meta object< / a > .
See < a href = "ntqmetaobject.html#property" > TQMetaObject::property< / a > () and < a href = "ntqmetaobject.html#propertyNames" > TQMetaObject::propertyNames< / a > () for
details.
< p > See also < a href = "objectmodel.html" > Object Model< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > bool < a name = "designable" > < / a > TQMetaProperty::designable ( < a href = "tqobject.html" > TQObject< / a > * o = 0 ) const
< / h3 > Returns TRUE if the property is designable for object < em > o< / em > ;
otherwise returns FALSE.
< p > If no object < em > o< / em > is given, the function returns a static
approximation.
< h3 class = fn > < a href = "tqstrlist.html" > TQStrList< / a > < a name = "enumKeys" > < / a > TQMetaProperty::enumKeys () const
< / h3 >
Returns the possible enumeration keys if this property is an
enumeration type (or a set type).
< p > < p > See also < a href = "#isEnumType" > isEnumType< / a > ().
< h3 class = fn > bool < a name = "isEnumType" > < / a > TQMetaProperty::isEnumType () const
< / h3 >
< p > Returns TRUE if the property's type is an enumeration value;
otherwise returns FALSE.
< p > < p > See also < a href = "#isSetType" > isSetType< / a > () and < a href = "#enumKeys" > enumKeys< / a > ().
< h3 class = fn > bool < a name = "isSetType" > < / a > TQMetaProperty::isSetType () const
< / h3 >
< p > 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.
< p > < p > See also < a href = "#isEnumType" > isEnumType< / a > () and < a href = "#enumKeys" > enumKeys< / a > ().
< h3 class = fn > int < a name = "keyToValue" > < / a > TQMetaProperty::keyToValue ( const char * key ) const
< / h3 >
Converts the enumeration key < em > key< / em > to its integer value.
< p > For set types, use < a href = "#keysToValue" > keysToValue< / a > ().
< p > < p > See also < a href = "#valueToKey" > valueToKey< / a > (), < a href = "#isSetType" > isSetType< / a > (), and < a href = "#keysToValue" > keysToValue< / a > ().
< h3 class = fn > int < a name = "keysToValue" > < / a > TQMetaProperty::keysToValue ( const < a href = "tqstrlist.html" > TQStrList< / a > & keys ) const
< / h3 >
Converts the list of keys < em > keys< / em > to their combined (OR-ed)
integer value.
< p > < p > See also < a href = "#isSetType" > isSetType< / a > () and < a href = "#valueToKey" > valueToKey< / a > ().
< h3 class = fn > const char * < a name = "name" > < / a > TQMetaProperty::name () const
< / h3 >
< p > Returns the name of the property.
< h3 class = fn > bool < a name = "reset" > < / a > TQMetaProperty::reset ( < a href = "tqobject.html" > TQObject< / a > * o ) const
< / h3 >
Tries to reset the property for object < em > o< / em > with a reset method.
On success, returns TRUE; otherwise returns FALSE.
< p > Reset methods are optional, usually only a few properties support
them.
< h3 class = fn > bool < a name = "scriptable" > < / a > TQMetaProperty::scriptable ( < a href = "tqobject.html" > TQObject< / a > * o = 0 ) const
< / h3 >
Returns TRUE if the property is scriptable for object < em > o< / em > ;
otherwise returns FALSE.
< p > If no object < em > o< / em > is given, the function returns a static
approximation.
< h3 class = fn > bool < a name = "stored" > < / a > TQMetaProperty::stored ( < a href = "tqobject.html" > TQObject< / a > * o = 0 ) const
< / h3 >
Returns TRUE if the property shall be stored for object < em > o< / em > ;
otherwise returns FALSE.
< p > If no object < em > o< / em > is given, the function returns a static
approximation.
< h3 class = fn > const char * < a name = "type" > < / a > TQMetaProperty::type () const
< / h3 >
< p > Returns the type of the property.
< h3 class = fn > const char * < a name = "valueToKey" > < / a > TQMetaProperty::valueToKey ( int value ) const
< / h3 >
Converts the enumeration value < em > value< / em > to its literal key.
< p > For set types, use < a href = "#valueToKeys" > valueToKeys< / a > ().
< p > < p > See also < a href = "#isSetType" > isSetType< / a > () and < a href = "#valueToKeys" > valueToKeys< / a > ().
< h3 class = fn > < a href = "tqstrlist.html" > TQStrList< / a > < a name = "valueToKeys" > < / a > TQMetaProperty::valueToKeys ( int value ) const
< / h3 >
Converts the set value < em > value< / em > to a list of keys.
< p > < p > See also < a href = "#isSetType" > isSetType< / a > () and < a href = "#valueToKey" > valueToKey< / a > ().
< h3 class = fn > bool < a name = "writable" > < / a > TQMetaProperty::writable () const
< / h3 >
< p > Returns TRUE if the property is writable; otherwise returns FALSE.
