InputEvent类是所有组件级别输入事件的根事件类。输入事件被传递到处理前的监听器通常由他们起源的源。这让监听器和组件的子类“消费”事件源不会使他们以默认方式处理。例如，一个按钮组件，将防止消耗mousePressed事件按钮被激活。

类声明

以下是声明 java.awt.event.InputEvent类：

public abstract class InputEvent
   extends ComponentEvent

字段域

以下为java.awt.event.InputEvent类字段：

• static int ALT_DOWN_MASK -- The Alt key extended modifier constant.

• static int ALT_GRAPH_DOWN_MASK -- The AltGraph key extended modifier constant.

• static int ALT_GRAPH_MASK -- The AltGraph key modifier constant.

• static int ALT_MASK -- The Alt key modifier constant.

• static int BUTTON1_DOWN_MASK -- The Mouse Button1 extended modifier constant.

• static int BUTTON1_MASK -- The Mouse Button1 modifier constant.

• static int BUTTON2_DOWN_MASK -- The Mouse Button2 extended modifier constant.

• static int BUTTON2_MASK -- The Mouse Button2 modifier constant.

• static int BUTTON3_DOWN_MASK -- The Mouse Button3 extended modifier constant.

• static int BUTTON3_MASK --The Mouse Button3 modifier constant.

• static int CTRL_DOWN_MASK -- The Control key extended modifier constant.

• static int CTRL_MASK -- The Control key modifier constant.

• static int META_DOWN_MASK -- The Meta key extended modifier constant.

• static int META_MASK -- The Meta key modifier constant.

• static int SHIFT_DOWN_MASK -- The Shift key extended modifier constant.

• static int SHIFT_MASK -- The Shift key modifier constant.
