构造方法详细信息

BasicInternalFrameTitlePane.SystemMenuBar

public BasicInternalFrameTitlePane.SystemMenuBar()

方法详细信息

isFocusTraversable

public boolean isFocusTraversable()

从类 Component 复制的描述

返回此 Component 是否可以成为焦点所有者。

覆盖：

类 Component 中的 isFocusTraversable

返回：

如果此 Component 是可以获得焦点的，则返回 true；否则返回 false

另请参见：

Component.setFocusable(boolean)

requestFocus

public void requestFocus()

从类 JComponent 复制的描述

请求此 Component 获得输入焦点。有关此方法的完整描述，请参阅 Component.requestFocus()。

注意，推荐不使用此方法，因为其行为是与平台相关的。我们建议使用 requestFocusInWindow()。若要了解有关焦点的更多信息，请参阅

覆盖：

类 JComponent 中的 requestFocus

另请参见：

Component.requestFocusInWindow(), Component.requestFocusInWindow(boolean)

paint

public void paint(Graphics g)

从类 JComponent 复制的描述

由 Swing 调用，以绘制组件。应用程序不应直接调用 paint，而是应该使用 repaint 方法来安排重绘组件。

此方法实际上将绘制工作委托给三个受保护的方法：paintComponent、paintBorder 和 paintChildren。按列出的顺序调用这些方法，以确保子组件出现在组件本身的顶部。一般而言，不应在分配给边框的 insets 区域绘制组件及其子组件。子类可以始终只重写此方法。只想特殊化 UI（外观）委托的 paint 方法的子类应该只重写 paintComponent。

覆盖：

类 JComponent 中的 paint

参数：

g - 在其中进行绘制的 Graphics 上下文

另请参见：

JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

isOpaque

public boolean isOpaque()

从类 JComponent 复制的描述

如果此组件是完全不透明的，则返回 true。

不透明组件将每个像素绘制在其矩形边界内。透明的组件则仅绘制其某些像素或根本不绘制任何像素，允许其下面的像素“透视出来”。因此，没有完全绘制其像素的组件则提供了一定程度的透明度。

保证总是完全绘制其内容的子类应该重写此方法并返回 true。

覆盖：

类 JComponent 中的 isOpaque

返回：

如果此组件是完全不透明的，则返回 true

另请参见：

JComponent.setOpaque(boolean)
