Swing JComponent類

JComponent類是除頂層容器外所有Swing組件的基類。要使用繼承自JComponent 一個組成部分，必須把的容納層次結(jié)構(gòu)，其根是一個頂層 Swing 容器組件。

類聲明

以下是聲明的 javax.swing.JComponent類：

public abstract class JComponent
   extends Container
      implements Serializable

字段域

以下是java.awt.Component 類的字段：

protected AccessibleContext accessibleContext -- AccessibleContext 可以帶此JComponent。
protected EventListenerList listenerList -- 此組件的事件偵聽器的列表。
static String TOOL_TIP_TEXT_KEY -- 注釋顯示當光標在組件上，也被稱為 "value tip", "flyover help", 或 "flyover label".
protected ComponentUI ui -- 此組件代表的外觀和風格。
static int UNDEFINED_CONDITION -- Constant used by some of the APIs to mean that no condition is defined.
static int WHEN_ANCESTOR_OF_FOCUSED_COMPONENT -- 常數(shù)用于registerKeyboardAction，意味著當接收組件是一個聚焦組件的基類，或者本身就是焦點的組件，該命令要調(diào)用。
static int WHEN_FOCUSED -- 常數(shù)用于registerKeyboardAction，意味著命令組件具有焦點時要調(diào)用。
static int WHEN_IN_FOCUSED_WINDOW -- 常數(shù)用于registerKeyboardAction，意味著當接收組件具有焦點的窗口，或者是本身的重點組成部分，該命令調(diào)用。
