This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences.

Constructor Detail

List.AccessibleAWTList

public List.AccessibleAWTList()
Method Detail

actionPerformed

public void actionPerformed(ActionEvent event)
Parameters:
event

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.

Parameters:
i - the zero-based index of selectable items

clearAccessibleSelection

public void clearAccessibleSelection()
Clears the selection in the object, so that nothing in the object is selected.

getAccessibleAt

public Accessible getAccessibleAt(Point p)
Returns the Accessible child contained at the local coordinate Point, if one exists.

Overrides:
getAccessibleAt in class Component.AccessibleAWTComponent
Parameters:
p
Returns:
the Accessible at the specified location, if it exists

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

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.

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

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

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.

Parameters:
i - the zero-based index of selected items
Returns:
an Accessible containing the selected item

getAccessibleSelectionCount

public int getAccessibleSelectionCount()
Returns the number of items currently selected. If no items are selected, the return value will be 0.

Returns:
the number of items currently selected.

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

isAccessibleChildSelected

public boolean isAccessibleChildSelected(int i)
Returns true if the current child of this object is selected.

Parameters:
i - the zero-based index of the child in this Accessible object.

itemStateChanged

public void itemStateChanged(ItemEvent event)
Parameters:
event

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.

Parameters:
i - the zero-based index of selectable items

selectAllAccessibleSelection

public void selectAllAccessibleSelection()
Causes every selected item in the object to be selected if the object supports multiple selections.
