Method Detail
-
getAccessibleStateSet
public AccessibleStateSet getAccessibleStateSet()
Get the state set of this object.- Overrides:
getAccessibleStateSetin classComponent.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:
getAccessibleRolein classComponent.AccessibleAWTComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
AccessibleRole
-
getAccessibleAt
public Accessible getAccessibleAt(Point p)
Returns the Accessible child contained at the local coordinate Point, if one exists.- Specified by:
getAccessibleAtin interfaceAccessibleComponent- Overrides:
getAccessibleAtin classComponent.AccessibleAWTComponent- Parameters:
p- the point defining the top-left corner of theAccessible, 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:
getAccessibleChildrenCountin classComponent.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:
getAccessibleChildin classComponent.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:
getAccessibleSelectionin classAccessibleContext- Returns:
- this object
- See Also:
AccessibleSelection
-
getAccessibleSelectionCount
public int getAccessibleSelectionCount()
Returns the number of items currently selected. If no items are selected, the return value will be 0.- Specified by:
getAccessibleSelectionCountin interfaceAccessibleSelection- 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:
getAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selected items- Returns:
- an Accessible containing the selected item
- See Also:
AccessibleSelection.getAccessibleSelectionCount()
-
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i)
Returns true if the current child of this object is selected.- Specified by:
isAccessibleChildSelectedin interfaceAccessibleSelection- Parameters:
i- the zero-based index of the child in this Accessible object.- Returns:
trueif the current child of this object is selected; elsefalse- See Also:
AccessibleContext.getAccessibleChild(int)
-
addAccessibleSelection
public void addAccessibleSelection(int i)
Adds the specified selected item in the object to the object's selection. If the object supports multiple selections, the specified item is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified item is already selected, this method has no effect.- Specified by:
addAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
AccessibleContext.getAccessibleChild(int)
-
removeAccessibleSelection
public void removeAccessibleSelection(int i)
Removes the specified selected item in the object from the object's selection. If the specified item isn't currently selected, this method has no effect.- Specified by:
removeAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
AccessibleContext.getAccessibleChild(int)
-
clearAccessibleSelection
public void clearAccessibleSelection()
Clears the selection in the object, so that nothing in the object is selected.- Specified by:
clearAccessibleSelectionin interfaceAccessibleSelection
-
selectAllAccessibleSelection
public void selectAllAccessibleSelection()
Causes every selected item in the object to be selected if the object supports multiple selections.- Specified by:
selectAllAccessibleSelectionin interfaceAccessibleSelection
