Method Detail

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns:

the number of accessible children of this object

See Also:

ComponentUI.getAccessibleChildrenCount(JComponent)

getAccessibleChild

public Accessible getAccessibleChild(int index)

Returns the number of accessible children of this object. The implementation of AccessibleJComboBox delegates this call to the UI of the associated JComboBox.

Overrides:

getAccessibleChild in class JComponent.AccessibleJComponent

Parameters:

index - the index of the accessible child to fetch

Returns:

the number of accessible children of this object

See Also:

ComponentUI.getAccessibleChild(JComponent, int)

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Returns the AccessibleSelection object associated with this object. AccessibleJComboBoxes handle their selection themselves, so this always returns this.

Overrides:

getAccessibleSelection in class AccessibleContext

Returns:

the AccessibleSelection object associated with this object

AccessibleSelection

getAccessibleSelection

public Accessible getAccessibleSelection(int index)

Returns the accessible selection from this AccssibleJComboBox.

Specified by:

isAccessibleChildSelected

public boolean isAccessibleChildSelected(int index)

Returns true if the accessible child with the specified index is selected, false otherwise.
