The QtVariantPropertyManager class provides and manages QVariant based properties.
QtVariantPropertyManager provides the addProperty() function which creates QtVariantProperty objects. The QtVariantProperty class is a convenience class handling QVariant based properties inheriting QtProperty. A QtProperty object created by a QtVariantPropertyManager instance can be converted into a QtVariantProperty object using the variantProperty() function.
The property's value can be retrieved using the value(), and set using the setValue() slot. In addition the property's type, and the type of its value, can be retrieved using the propertyType() and valueType() functions respectively.
A property's type is a QVariant::Type enumerator value, and usually a property's type is the same as its value type. But for some properties the types differ, for example for enums, flags and group types in which case QtVariantPropertyManager provides the enumTypeId(), flagTypeId() and groupTypeId() functions, respectively, to identify their property type (the value types are QVariant::Int for the enum and flag types, and QVariant::Invalid for the group type).
Use the isPropertyTypeSupported() function to check if a particular property type is supported. The currently supported property types are:
\table \header \o Property Type \o Property Type Id \row \o int \o QVariant::Int \row \o double \o QVariant::Double \row \o bool \o QVariant::Bool \row \o QString \o QVariant::String \row \o QDate \o QVariant::Date \row \o QTime \o QVariant::Time \row \o QDateTime \o QVariant::DateTime \row \o QKeySequence \o QVariant::KeySequence \row \o QChar \o QVariant::Char \row \o QLocale \o QVariant::Locale \row \o QPoint \o QVariant::Point \row \o QPointF \o QVariant::PointF \row \o QSize \o QVariant::Size \row \o QSizeF \o QVariant::SizeF \row \o QRect \o QVariant::Rect \row \o QRectF \o QVariant::RectF \row \o QColor \o QVariant::Color \row \o QSizePolicy \o QVariant::SizePolicy \row \o QFont \o QVariant::Font \row \o QCursor \o QVariant::Cursor \row \o enum \o enumTypeId() \row \o flag \o flagTypeId() \row \o group \o groupTypeId() \endtable
Each property type can provide additional attributes, e.g. QVariant::Int and QVariant::Double provides minimum and maximum values. The currently supported attributes are:
\table \header \o Property Type \o Attribute Name \o Attribute Type \row \o int
\o minimum \o QVariant::Int \row \o \o maximum \o QVariant::Int \row \o \o singleStep \o QVariant::Int \row \o double
\o minimum \o QVariant::Double \row \o \o maximum \o QVariant::Double \row \o \o singleStep \o QVariant::Double \row \o \o decimals \o QVariant::Int \row \o bool
\o textVisible \o QVariant::Bool \row \o QString \o regExp \o QVariant::RegExp \row \o \o echoMode \o QVariant::Int \row \o QDate \o minimum \o QVariant::Date \row \o \o maximum \o QVariant::Date \row \o QPointF \o decimals \o QVariant::Int \row \o QSize \o minimum \o QVariant::Size \row \o \o maximum \o QVariant::Size \row \o QSizeF \o minimum \o QVariant::SizeF \row \o \o maximum \o QVariant::SizeF \row \o \o decimals \o QVariant::Int \row \o QRect \o constraint \o QVariant::Rect \row \o QRectF \o constraint \o QVariant::RectF \row \o \o decimals \o QVariant::Int \row \o enum
\o enumNames \o QVariant::StringList \row \o \o enumIcons \o iconMapTypeId() \row \o flag
\o flagNames \o QVariant::StringList \endtable
The attributes for a given property type can be retrieved using the attributes() function. Each attribute has a value type which can be retrieved using the attributeType() function, and a value accessible through the attributeValue() function. In addition, the value can be set using the setAttribute() slot.
QtVariantManager also provides the valueChanged() signal which is emitted whenever a property created by this manager change, and the attributeChanged() signal which is emitted whenever an attribute of such a property changes.

QtVariantPropertyManager | ( | QObject * | parent = 0 | ) |
Creates a manager with the given parent.
Definition at line 1011 of file qtvariantproperty.cpp.
|
override |
Destroys this manager, and all the properties it has created.
Definition at line 1347 of file qtvariantproperty.cpp.
|
virtual |
Creates and returns a variant property of the given propertyType with the given name.
If the specified propertyType is not supported by this variant manager, this function returns 0.
Do not use the inherited QtAbstractPropertyManager::addProperty() function to create a variant property (that function will always return 0 since it will not be clear what type the property should have).
Definition at line 1403 of file qtvariantproperty.cpp.
|
signal |
This signal is emitted whenever an attribute of a property created by this manager changes its value, passing a pointer to the property, the attribute and the new value as parameters.
|
virtual |
Returns a list of the given propertyType 's attributes.
Reimplemented in OptionalVariantManager.
Definition at line 1820 of file qtvariantproperty.cpp.
|
virtual |
Returns the type of the specified attribute of the given propertyType.
If the given propertyType is not supported by this manager, or if the given propertyType does not possess the specified attribute, this function returns QVariant::Invalid.
Reimplemented in OptionalVariantManager.
Definition at line 1843 of file qtvariantproperty.cpp.
|
virtual |
Returns the given property's value for the specified attribute
If the given property was not created by this manager, or if the specified attribute does not exist, this function returns an invalid variant.

Returns the type id for an enum property.
Note that the property's value type can be retrieved using the valueType() function (which is QVariant::Int for the enum property type).
Definition at line 87 of file qtvariantproperty.cpp.
|
static |
Returns the type id for a flag property.
Note that the property's value type can be retrieved using the valueType() function (which is QVariant::Int for the flag property type).
Definition at line 101 of file qtvariantproperty.cpp.
|
static |
Returns the type id for a group property.
Note that the property's value type can be retrieved using the valueType() function (which is QVariant::Invalid for the group property type, since it doesn't provide any value).
