Constructs new AccessibleAWTList

Methods

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Get the state set of this object.

Overrides:
getAccessibleStateSet in class Component.AccessibleAWTComponent
Returns:
an instance of AccessibleState containing the current state of the object
See Also:
AccessibleState

getAccessibleRole

public AccessibleRole getAccessibleRole()

Get the role of this object.

Overrides:
getAccessibleRole in class Component.AccessibleAWTComponent
Returns:
an instance of AccessibleRole describing the role of the object

getAccessibleAt

public Accessible getAccessibleAt(Point p)

Returns the Accessible child contained at the local coordinate Point, if one exists.

Specified by:
getAccessibleAt in interface AccessibleComponent
Overrides:
getAccessibleAt in class Component.AccessibleAWTComponent
Parameters:
p - the point defining the top-left corner of the Accessible, given in the coordinate space of the object's parent
Returns:
the Accessible at the specified location, if it exists

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.

Overrides:
getAccessibleChildrenCount in class Component.AccessibleAWTComponent
Returns:
the number of accessible children in the object.

getAccessibleChild

public Accessible getAccessibleChild(int i)

Return the nth Accessible child of the object.

Overrides:
getAccessibleChild in class Component.AccessibleAWTComponent
Parameters:
i - zero-based index of child
Returns:
the nth Accessible child of the object
See Also:
AccessibleContext.getAccessibleChildrenCount()

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.

Overrides:
getAccessibleSelection in class AccessibleContext
Returns:
this object
See Also:

getAccessibleSelectionCount

public int getAccessibleSelectionCount()

Returns the number of items currently selected. If no items are selected, the return value will be 0.

Specified by:

Returns:
the number of items currently selected.

getAccessibleSelection

public Accessible getAccessibleSelection(int i)

Returns an Accessible representing the specified selected item in the object. If there isn't a selection, or there are fewer items selected than the integer passed in, the return value will be null.

Specified by:
