public Choice.AccessibleAWTChoice()

Default constructor which simply calls the super class for generic component accessibility handling.

Method Detail

getAccessibleAction

public javax.accessibility.AccessibleAction getAccessibleAction()

Returns an implementation of the AccessibleAction interface for this accessible object. In this case, the current instance is simply returned (with a more appropriate type), as it also implements the accessible action as well as the context.

Overrides:

getAccessibleAction in class javax.accessibility.AccessibleContext

Returns:

the accessible action associated with this context.

See Also:

AccessibleAction

getAccessibleRole

public javax.accessibility.AccessibleRole getAccessibleRole()

Returns the role of this accessible object.

Overrides:

getAccessibleRole in class Component.AccessibleAWTComponent

Returns:

the instance of AccessibleRole, which describes this object.

See Also:

AccessibleRole

getAccessibleActionCount

public int getAccessibleActionCount()

Returns the number of actions associated with this accessible object. In this case, it is the number of choices available.

Specified by:

getAccessibleActionCount in interface javax.accessibility.AccessibleAction

Returns:

the number of choices available.

See Also:

AccessibleAction.getAccessibleActionCount()

getAccessibleActionDescription

public java.lang.String getAccessibleActionDescription(int i)

Returns a description of the action with the supplied id. In this case, it is the text used in displaying the particular choice on-screen.

Specified by:

getAccessibleActionDescription in interface javax.accessibility.AccessibleAction

Parameters:

i - the id of the choice whose description should be retrieved.

Returns:

the String used to describe the choice.

See Also:

doAccessibleAction

public boolean doAccessibleAction(int i)

Executes the action with the specified id. In this case, calling this method provides the same behaviour as would choosing a choice from the list in a visual manner.

Parameters:

i - the id of the choice to select.

Returns:

true if a valid choice was specified.
