c - 创建UI对象的组件
public void uninstallUI(JComponent c)
installUI上完成的installUI 。
当该UIComponent实例作为指定组件的UI委托被删除时,将调用此方法。
该方法应该撤消在installUI中执行的installUI ,小心使JComponent实例处于干净状态(无外部侦听器,外观特定属性对象等)。
这应该包括以下内容:
uninstallUI在
BasicMenuItemUI类
c - 正在删除此UI代理的组件;
这个参数经常被忽略,但如果UI对象是无状态的并且被多个组件共享,则可能会被使用
ComponentUI.installUI(javax.swing.JComponent) ,
JComponent.updateUI()
protected void installDefaults()
protected void installListeners()
protected void uninstallDefaults()
protected void uninstallListeners()
public SynthContext getContext(JComponent c)
getContext在接口
SynthUI
c - 组件请求SynthContext。
protected Dimension getPreferredMenuItemSize(JComponent c, Icon checkIcon, Icon arrowIcon, int defaultTextIconGap)
public void update(Graphics g, JComponent c)
paint(SynthContext,Graphics)方法。
通常,此方法不需要被子类覆盖。 所有Look和Feel渲染代码应该在paint方法中。
update在
BasicMenuItemUI
g - 用于绘画的
Graphics对象
c - 正在涂漆的组件
paint(SynthContext,Graphics)
public void paint(Graphics g, JComponent c)
Synth Look and Feel不使用此方法。 绘画由paint(SynthContext,Graphics)处理。

protected void paint(SynthContext context, Graphics g)
context - 正在绘制的组件的上下文
