qmetaproperty.3qt - Man Page

#include <qmetaobject.h>

The QMetaProperty class stores meta data about a property.

Property meta data includes type(), name(), and whether a property is writable(), designable() and stored().

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.

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 object. See QMetaObject::property() and QMetaObject::propertyNames() for details.

See also Object Model.

Returns TRUE if the property is designable for object o; otherwise returns FALSE.

If no object o is given, the function returns a static approximation.

Returns the possible enumeration keys if this property is an enumeration type (or a set type).

See also isEnumType().

Returns TRUE if the property's type is an enumeration value; otherwise returns FALSE.

See also isSetType() and enumKeys().

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.

See also isEnumType() and enumKeys().

Converts the enumeration key key to its integer value.

For set types, use keysToValue().

See also valueToKey(), isSetType(), and keysToValue().

Converts the list of keys keys to their combined (OR-ed) integer value.

See also isSetType() and valueToKey().

Returns the name of the property.

Tries to reset the property for object o with a reset method. On success, returns TRUE; otherwise returns FALSE.

Reset methods are optional, usually only a few properties support them.

Returns TRUE if the property is scriptable for object o; otherwise returns FALSE.

If no object o is given, the function returns a static approximation.

Returns TRUE if the property shall be stored for object o; otherwise returns FALSE.

If no object o is given, the function returns a static approximation.

Returns the type of the property.

Converts the enumeration value value to its literal key.

For set types, use valueToKeys().

See also isSetType() and valueToKeys().

Converts the set value value to a list of keys.

See also isSetType() and valueToKey().

Returns TRUE if the property is writable; otherwise returns FALSE.
