SWING AWTEvent事件類

它是所有 AWTEvent 中事件的根事件類。這個類及其子類取代原來的 java.awt.Event類。 java.awt包中定義這個類。這個類有一個 getID() 方法,該方法可以用來確定事件的類型。

類聲明

以下是聲明 java.awt.AWTEvent類:

public class AWTEvent
   extends EventObject

字段域

以下是java.awt.AWTEvent 類的字段:

  • static int ACTION_FIRST -- The first number in the range of ids used for action events.

  • static long ACTION_EVENT_MASK -- The event mask for selecting action events.

  • static long ADJUSTMENT_EVENT_MASK -- The event mask for selecting adjustment events.

  • static long COMPONENT_EVENT_MASK -- The event mask for selecting component events.

  • protected boolean consumed -- Controls whether or not the event is sent back down to the peer once the source has processed it - false means it's sent to the peer; true means it's not.

  • static long CONTAINER_EVENT_MASK -- The event mask for selecting container events.

  • static long FOCUS_EVENT_MASK -- The event mask for selecting focus events.

  • static long HIERARCHY_BOUNDS_EVENT_MASK -- The event mask for selecting hierarchy bounds events.

  • static long HIERARCHY_EVENT_MASK -- The event mask for selecting hierarchy events.

  • protected int id -- The event's id.

  • static long INPUT_METHOD_EVENT_MASK -- The event mask for selecting input method events.

  • static long INVOCATION_EVENT_MASK -- The event mask for selecting invocation events.

  • static long KEY_EVENT_MASK -- The event mask for selecting key events.

  • static long MOUSE_EVENT_MASK -- The event mask for selecting mouse events.

  • static long MOUSE_MOTION_EVENT_MASK -- The event mask for selecting mouse motion events.

  • static long MOUSE_WHEEL_EVENT_MASK -- The event mask for selecting mouse wheel events.

  • static long PAINT_EVENT_MASK -- The event mask for selecting paint events.

  • static int RESERVED_ID_MAX -- The maximum value for reserved SWING event IDs.

  • static long TEXT_EVENT_MASK -- The event mask for selecting text events.

  • static long WINDOW_EVENT_MASK -- The event mask for selecting window events.
