AccessibleAWTChoice

public AccessibleAWTChoice()
Default constructor which simply calls the super class for generic component accessibility handling.

Method Details

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.
Specified by:
doAccessibleAction in interface AccessibleAction
Parameters:
i - the id of the choice to select.
Returns:
true if a valid choice was specified.

getAccessibleAction

public 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 interface AccessibleContext
Returns:
the accessible action associated with this context.

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 AccessibleAction
Returns:
the number of choices available.

getAccessibleActionDescription

public 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 AccessibleAction
Parameters:
i - the id of the choice whose description should be retrieved.
Returns:
the String used to describe the choice.

getAccessibleRole

public AccessibleRole getAccessibleRole()
Returns the role of this accessible object.
Overrides:
getAccessibleRole in interface Component.AccessibleAWTComponent
Returns:
the instance of AccessibleRole, which describes this object.
