Interface IActionBinder

All Known Implementing Classes:

SwingDataServiceAction

public interface IActionBinder

IActionBinder has the ability to automatically change an enabled state on an Action when the arguments for the Action change. The meaning of the argument and the changes that trigger an enabled state change are up to the implementation. For example, an Action that invokes a service call could change its enabled state when the parameters for that service call change.

Nested Class Summary

static class	IActionBinder.ActionBinderEvent A action binder event is fired before and after the ActionBinder's action is performed.
static interface	IActionBinder.ActionBinderListener Interface used to register for action triggering notification.

Field Summary

static int	ENABLE_DISABLE_ACTION Bound visual will be disabled when the argument is changed
static int	ENABLE_ENABLE_ACTION Bound visual will be enabled when the argument is changed
static int	ENABLE_NO_ACTION Bound visual's enabled state will not change when the argument is changed

Method Summary

void	addActionBinderListener(IActionBinder.ActionBinderListener l) Add a new ActionBinderListner to the listener list.
int	getActionType() Get the type of the action
boolean	isEnabled() Retrieves the enabled state of the action.
void	removeActionBinderListener(IActionBinder.ActionBinderListener l) Remove an existing ActionBinderListener from the listener list.
void	setActionType(int type) Set the way the action binder will drive its enable state.
void	setEnabled(boolean state) Set the enabled state of the action.
