isFocusTraversable 方法重写，继承类
Component
true
Component聚焦；
false否则
Component.setFocusable(boolean)
public void requestFocus()
JComponent
Component获取输入焦点。参考
Component.requestFocus()对本方法的完整描述。
请注意，这种方法的使用是气馁，因为它的行为是依赖于平台的。相反，我们建议使用requestFocusInWindow()。如果你想在焦点，更多信息见 How to Use the Focus Subsystem，java教程中的一部分。
public void paint(Graphics g)
JComponent
paint直接，而应该使用
repaint方法来重绘组件的时间表。
这种方法实际上代表绘画工作三保护的方法：paintComponent，paintBorder，和paintChildren。他们被称为在列出的顺序，以确保孩子出现在组件本身的顶部。一般来说，组件和它的孩子们不应该画的插图面积分配到边境。子类可以重写此方法，就像总是。一类是只想专注UI（外观）代表的paint方法应该重写paintComponent。
public boolean isOpaque()
JComponent
一个不透明的组件画在它的矩形边界内的每一个像素。一个非不透明的组件只画出它的像素的一个子集，或者根本没有，允许它在它下面的像素“显示通过”。因此，一个不完全画它的像素的组件提供了一个透明的程度。
保证总是完全地画他们的内容的子类应该重写这个方法，并返回真。
isOpaque 方法重写，继承类
JComponent
JComponent.setOpaque(boolean)
