Detailed Description
Attributes are key-value pairs. Values are stored in QVariant.
The QAccessible::Attribute enumeration describes the available keys and documents which type to use for the value of each key.
While the text-specific attributes handled by QAccessibleTextInterface::attributes are specific to objects implementing text and are specific to a specific text position/offset, the attributes handled by the QAccessibleAttributesInterface can be used for objects of any role and apply for the whole object.
Classes already implementing QAccessibleTextInterface for text-specific attrtibutes may want to implement QAccessibleAttributesInterface in addition for object-specific attributes.
Member Function Documentation
[virtual noexcept] QAccessibleAttributesInterface::~QAccessibleAttributesInterface()
Destroys the QAccessibleAttributesInterface.
[pure virtual] QList<QAccessible::Attribute> QAccessibleAttributesInterface::attributeKeys() const
Returns the keys of all attributes the object supports. The QAccessible::Attribute enumeration describes available keys.
[pure virtual] QVariant QAccessibleAttributesInterface::attributeValue(QAccessible::Attribute key) const
Returns the value of the attribute key of this object.
If the attribute is set for this object, a value of the type documented for the given key in the documentation of the QAccessible::Attribute enumeration is returned in the QVariant.
Otherwise, an invalid QVariant is returned.
