Method Detail

propertyChange

public void propertyChange(PropertyChangeEvent e)

Track changes to selection model, column model, etc. so as to be able to re-place listeners on those in order to pass on information to the Accessibility PropertyChange mechanism

Specified by:

propertyChange in interface PropertyChangeListener

tableChanged

public void tableChanged(TableModelEvent e)

Track changes to the table contents

Specified by:

tableChanged in interface TableModelListener

tableRowsInserted

public void tableRowsInserted(TableModelEvent e)

Track changes to the table contents (row insertions)

tableRowsDeleted

public void tableRowsDeleted(TableModelEvent e)

Track changes to the table contents (row deletions)

columnAdded

public void columnAdded(TableColumnModelEvent e)

Track changes to the table contents (column insertions)

Specified by:

columnAdded in interface TableColumnModelListener

columnRemoved

public void columnRemoved(TableColumnModelEvent e)

Track changes to the table contents (column deletions)

Specified by:

columnRemoved in interface TableColumnModelListener

columnMoved

public void columnMoved(TableColumnModelEvent e)

Track changes of a column repositioning.

Specified by:

columnMoved in interface TableColumnModelListener

See Also:

TableColumnModelListener

columnMarginChanged

public void columnMarginChanged(ChangeEvent e)

Track changes of a column moving due to margin changes.

Specified by:

columnMarginChanged in interface TableColumnModelListener

See Also:

TableColumnModelListener

columnSelectionChanged

public void columnSelectionChanged(ListSelectionEvent e)

Track that the selection model of the TableColumnModel changed.

Specified by:

columnSelectionChanged in interface TableColumnModelListener

See Also:

TableColumnModelListener

editingStopped

public void editingStopped(ChangeEvent e)

Track changes to a cell's contents. Invoked when editing is finished. The changes are saved, the editor object is discarded, and the cell is rendered once again.

Specified by:

editingStopped in interface CellEditorListener

See Also:

CellEditorListener

editingCanceled

public void editingCanceled(ChangeEvent e)

Invoked when editing is canceled. The editor object is discarded and the cell is rendered once again.

Specified by:

editingCanceled in interface CellEditorListener

See Also:

CellEditorListener

valueChanged

public void valueChanged(ListSelectionEvent e)

Track changes to table cell selections

Specified by:

valueChanged in interface ListSelectionListener

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Get the AccessibleSelection associated with this object if one exists. Otherwise return null.

Returns:

the AccessibleSelection, or null

Overrides:

getAccessibleSelection in class AccessibleContext

getAccessibleRole

public AccessibleRole getAccessibleRole()

Get the role of this object.

Returns:

an instance of AccessibleRole describing the role of the object

Overrides:

getAccessibleRole in class JComponent.AccessibleJComponent

See Also:

AccessibleRole

getAccessibleAt

public Accessible getAccessibleAt(Point p)

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

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, if it exists, at the specified location; else null

Overrides:

getAccessibleAt in class JComponent.AccessibleJComponent

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.

Returns:

the number of accessible children in the object.

Overrides:

getAccessibleChildrenCount in class JComponent.AccessibleJComponent

getAccessibleChild

public Accessible getAccessibleChild(int i)

Return the nth Accessible child of the object.

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

Overrides:

getAccessibleChild in class JComponent.AccessibleJComponent

getAccessibleSelectionCount

public int getAccessibleSelectionCount()

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

Specified by:

getAccessibleSelectionCount in interface AccessibleSelection

Returns:

the number of items currently selected.

getAccessibleSelection

public Accessible getAccessibleSelection(int i)

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

Note that the index represents the i-th selected child, which is different from the i-th child.

Specified by:

getAccessibleSelection in interface AccessibleSelection

Parameters:

i - the zero-based index of selected children

Returns:

the i-th selected child

See Also:

getAccessibleSelectionCount()

Returns:

true if the current child of this object is selected

See Also:

AccessibleContext.getAccessibleChild(int)

addAccessibleSelection

If the object supports multiple selections, the specified child is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified child is already selected, this method has no effect. This method only works on JTables which have individual cell selection enabled.

Specified by:

addAccessibleSelection in interface AccessibleSelection

Parameters:
