Detailed Description

Implement this interface for exposing various aspects of a class's content.

This interface serves two purposes: On the one hand it gives access to the tree structure in which all accessible objects are organized. Each node in this tree supports this interface. On the other hand it gives access to objects that expose the represented content. That are role, state, name, description, and relations to other objects. Take an OK button of a dialog as an example. Its role is AccessibleRole::BUTTON, its name is "OK", and its description is something like "Accepts all changes made in the dialog".

Since: OOo 1.1.2

Member Function Documentation

◆ getAccessibleChild()

XAccessible getAccessibleChild	(	[in] hyper	i	)
raises	(	::com::sun::star::lang::IndexOutOfBoundsException
	)

Returns the i-th child of this object.

The order in which the children are enumerated is implementation dependent.

Parameters

i	The index may have any value. If it is outside the range from 0 to n-1, with n being the number of children as returned by XAccessibleContext::getAccessibleChild() an empty reference is returned.

Returns: If the object has an i-th child the returned value is a reference to that child. Otherwise an empty reference is returned.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException If no child with the given index exists then an com::sun::star::lang::IndexOutOfBoundsException exception is thrown.

◆ getAccessibleChildCount()

hyper getAccessibleChildCount ( )

Return the number of children.

Returns the number of accessible children of the object.

Returns: The returned value is non-negative.

◆ getAccessibleDescription()

string getAccessibleDescription ( )

Returns the object's description.

Returns the object's localized description. The description should complement the more generic descriptions given by an object's role and name.

Returns: The returned string is the object's localized description.

◆ getAccessibleIndexInParent()

hyper getAccessibleIndexInParent ( )

Returns the index of this object in its accessible parent.

If you call getAccessibleChild on the object's parent with the index returned by this function you get a reference to this object.

Returns: The returned index is zero based.

◆ getAccessibleName()

string getAccessibleName ( )

Return the object's localized name.

See XAccessibleContext::getAccessibleRole()'s documentation for the relation between an object's name and role. Names should be unique, at least between children of the same parent, although the uniqueness is neither enforced nor used inside the API.

Returns: The returned string is the object's localized name.

◆ getAccessibleParent()

XAccessible getAccessibleParent ( )

Returns the parent of this object.

This function may be called for every node, including the root node, of the accessible tree.

Returns: The returned reference points to a valid object for all but the root node. If called for the root node an empty reference is returned.

◆ getAccessibleRelationSet()

XAccessibleRelationSet getAccessibleRelationSet ( )

Returns the set of relations defined for this object.

The returned set of relations is a copy of this object's relation set: changing the returned object does not change this object's relations.

There are two ways to represent an empty list of relations: Return an empty reference or return a valid object that contains an empty list.

Returns: The returned value is either an empty reference or a reference to a valid object that represents a copy of the objects list of relations.

◆ getAccessibleRole()

short getAccessibleRole ( )

Returns the role of this object.

The role is a generic description of an objects function. The relation between role and name is similar to the relation between class and object.

Returns: The returned value is a role defined in the enumeration AccessibleRole.

See also: AccessibleRole for a list of the available roles.

◆ getAccessibleStateSet()

hyper getAccessibleStateSet ( )

Returns the set of states that are currently active for this object.

See the documentation of AccessibleStateType for a description of the individual states.

See also: AccessibleStateType

◆ getLocale()

::com::sun::star::lang::Locale getLocale	(		)
raises	(	IllegalAccessibleComponentStateException
	)

Returns the locale of the component.

This locale is used for example to determine the language to use for the name and description texts.

Returns: If this object does not have a locale, the locale of its parent is returned. If it does not have (yet) a parent it throws the exception IllegalAccessibleComponentStateException.
