interface XAccessibleContext

Description: Implement this interface for exposing various aspects of a class' 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

Methods' Details

getAccessibleChildCount

long
getAccessibleChildCount();

Description: Return the number of children.; Returns the number of accessible children of the object.
Returns: The returned value is non-negative.

getAccessibleChild

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

Description: Returns the i-th child of this object.; The order in which the children are enumerated is implementation dependend.
Parameter 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.
Throws: ::com::sun::star::lang::IndexOutOfBoundsException If no child with the given index exists then an ::com::sun::star::lang::IndexOutOfBoundsException exception is thrown.

getAccessibleParent

XAccessible
getAccessibleParent();

Description: 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.

getAccessibleIndexInParent

long
getAccessibleIndexInParent();

Description: Returns the index of this object in its accessible parent.; If you call getAccessibeChild 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.

getAccessibleRole

short
getAccessibleRole();

Description: 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.

getAccessibleDescription

string
getAccessibleDescription();

Description: 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.

getAccessibleName

string
getAccessibleName();

Description: 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.

getAccessibleRelationSet

XAccessibleRelationSet
getAccessibleRelationSet();

Description

Returns the set of relations defined for this object.

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

aThere 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 referece or a reference to a valid object that represents a copy of the objects list of relations.

getAccessibleStateSet

XAccessibleStateSet
getAccessibleStateSet();

Description: Returns the set of states that are currently active for this object.; The returned state set is a copy: Changing the returned state set will not be refelected by changing the object's set of states. See the documentation of XAccessibleStateSet for a description of the individual states.
Returns: A reference to this object's state set or an empty reference if states are not supported.
See also: XAccessibleStateSet

getLocale

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

Description: 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.
Throws: IllegalAccessibleComponentStateException when this object does not (yet) have a parent.
