Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

The EventPriority class defines constant values for the priority argument of the addEventListener() method of EventDispatcher.

The higher the number, the higher the priority of the event listener. All listeners with priority N will be processed before listeners of priority N - 1. If two or more listeners share the same priority, they are processed in the order in which they were added.

Priorities can be positive, 0, or negative. The default priority is 0.

You should not write code that depends on the numeric values of these constants. They are subject to change in future versions of Flex.



Public Constants
 ConstantDefined By
  BINDING : int = 100
[static] Autogenerated event handlers that evaluate data-binding expressions need to be executed before any others, so they have a higher priority than the default.
EventPriority
  CURSOR_MANAGEMENT : int = 200
[static] The CursorManager has handlers for mouse events which must be executed before other mouse event handlers, so they have a high priority.
EventPriority
  DEFAULT : int = 0
[static] Event handlers on component instances are executed with the default priority, 0.
EventPriority
  DEFAULT_HANDLER : int = -50
[static] Some components listen to events that they dispatch on themselves and let other listeners call the preventDefault() method to tell the component not to perform a default action.
EventPriority
  EFFECT : int = -100
[static] Autogenerated event handlers that trigger effects are executed after other event handlers on component instances, so they have a lower priority than the default.

BINDINGConstant
public static const BINDING:int = 100

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Autogenerated event handlers that evaluate data-binding expressions need to be executed before any others, so they have a higher priority than the default.

CURSOR_MANAGEMENTConstant 
public static const CURSOR_MANAGEMENT:int = 200

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

The CursorManager has handlers for mouse events which must be executed before other mouse event handlers, so they have a high priority.

DEFAULTConstant 
public static const DEFAULT:int = 0

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Event handlers on component instances are executed with the default priority, 0.

DEFAULT_HANDLERConstant 
public static const DEFAULT_HANDLER:int = -50

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Some components listen to events that they dispatch on themselves and let other listeners call the preventDefault() method to tell the component not to perform a default action. Those components must listen with a lower priority than the default priority, so that the other handlers are executed first and have a chance to call preventDefault().

EFFECTConstant 
public static const EFFECT:int = -100

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Autogenerated event handlers that trigger effects are executed after other event handlers on component instances, so they have a lower priority than the default.
