Detailed Description

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.

Constructor & Destructor Documentation

◆ QtVariantPropertyManager()

QtVariantPropertyManager ( QObject *  parent = 0)

Creates a manager with the given parent.

+ Here is the call graph for this function:

◆ ~QtVariantPropertyManager()

~QtVariantPropertyManager ( )
override

Destroys this manager, and all the properties it has created.

Member Function Documentation

◆ addProperty()

QtVariantProperty * addProperty ( int  propertyType,
const QString &  name = QString() 
)
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).
