Detailed Description

Implement this interface to represent a selection of accessible objects.

This interface is the standard mechanism to obtain and modify the currently selected children. Every object that has children that can be selected should support this interface.

The XAccessibleSelection interface has to be implemented in conjunction with the XAccessibleContext interface that provides the children on which the first operates.

It depends on the class implementing this interface, whether it supports single or multi selection.

Since

OOo 1.1.2

Member Function Documentation

clearAccessibleSelection()

void clearAccessibleSelection

(

)

Clears the selection, so that no children of the object are selected.

deselectAccessibleChild()

void deselectAccessibleChild	(	[in] hyper	nChildIndex	)
raises	(	::com::sun::star::lang::IndexOutOfBoundsException
	)

Removes the specified child from the set of this object's selected children.

Note that not all applications support deselection: calls to this method may be silently ignored.

Parameters

nChildIndex

This index refers to all children not just the selected ones. If the specified child is not selected or it can not be deselected for any reason then the method call is silently ignored.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException

if the given index does not lie in the valid range of 0 up to, but not including, the result of XAccessibleContext::getAccessibleChildCount().

getSelectedAccessibleChild()

XAccessible getSelectedAccessibleChild	(	[in] hyper	nSelectedChildIndex	)
raises	(	::com::sun::star::lang::IndexOutOfBoundsException
	)

Returns the specified selected Accessible child.

Parameters

nSelectedChildIndex

This index refers only to the selected children, not to all the children of this object. Even if all children are selected, the indices enumerating the selected children need not be the same as those enumerating all children. If only single selection is supported the only valid value is 0.

Returns

If the index is valid, i.e. not negative and lower than the number of selected children, then a valid reference to the corresponding XAccessible child is returned. Otherwise an exception is thrown.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException

if the given index does not lie in the valid range of 0 up to the result of XAccessibleRelationSet::getAccessibleChildCount()-1.

getSelectedAccessibleChildCount()

hyper getSelectedAccessibleChildCount

(

)

Returns the number of Accessible children that are currently selected.

This number specifies the valid interval of indices that can be used as arguments for the method XAccessibleSelection::getSelectedAccessibleChild().

Returns

Returns the number of selected children of this object or 0 if no child is selected.

isAccessibleChildSelected()

boolean isAccessibleChildSelected	(	[in] hyper	nChildIndex	)
raises	(	::com::sun::star::lang::IndexOutOfBoundsException
	)

Determines if the specified child of this object is selected.

Parameters

nChildIndex

Index of the child for which to detect whether it is selected. This index refers to all the children of this object.

Returns

Returns TRUE if the specified child is selected and FALSE if it is not selected.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException

if the given index does not lie in the valid range of 0 up to the result of XAccessibleContext::getAccessibleChildCount()-1.

selectAccessibleChild()

void selectAccessibleChild	(	[in] hyper	nChildIndex	)
raises	(	::com::sun::star::lang::IndexOutOfBoundsException
	)

Selects the specified Accessible child of the object.

Depending on the implementing class the child is added to the current set a selected children (multi selection) or a previously selected child is deselected first (single selection).

Parameters

nChildIndex

Index of the child which is to add to the selection. This index refers to all the children of this object.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException

if the given index does not lie in the valid range of 0 up to the result of XAccessibleContext::getAccessibleChildCount()-1.

selectAllAccessibleChildren()

void selectAllAccessibleChildren

(

)

Select all children.

Causes every child of the object to be selected if the object supports multiple selections. If multiple selection is not supported then the first child, if it exists, is selected and all other children are deselected.
