Method Detail

getActionCount

void getActionCount(AccessibleActionEvent e)
Returns the number of accessible actions available in this object.

If there are more than one, the first one (index 0) is considered the "default" action of the object.

Parameters:
e - an event object containing the following fields:
  • [out] count - the number of actions, or zero if there are no actions

doAction

void doAction(AccessibleActionEvent e)
Performs the specified action on the object.

Parameters:
e - an event object containing the following fields:
  • [in] index - a 0 based index specifying the action to perform. If the index lies outside the valid range no action is performed.
  • [out] result - set to ACC.OK if the action was performed.

getDescription

void getDescription(AccessibleActionEvent e)
Returns a description of the specified action.

Parameters:
e - an event object containing the following fields:
  • [in] index - a 0 based index specifying which action's description to return
  • [out] result - a localized string describing the specified action, or null if the index lies outside the valid range

getKeyBinding

void getKeyBinding(AccessibleActionEvent e)
Returns a string representing one or more key bindings, if there are any, associated with the specified action.

The returned string is of the following form: mnemonic;accelerator for example: "C;CTRL+C" for the Copy item in a typical Edit menu.

Parameters:
e - an event object containing the following fields:
  • [in] index - a 0 based index specifying which action's key bindings to return
  • [out] result - a semicolon-delimited string of localized key bindings (example: "C;CTRL+C"), or null if the index lies outside the valid range

getName

void getName(AccessibleActionEvent e)
Returns the name of the specified action.

There is no need to implement this method for single action controls since that would be redundant with AccessibleControlListener.getDefaultAction.

Parameters:
e - an event object containing the following fields:
  • [in] index - a 0 based index specifying which action's name to return
  • [in] localized - a boolean indicating whether or not to return a localized name
  • [out] result - the name of the specified action, or null if the index lies outside the valid range
