                        Color background,
                        Color shadow,
                        Color darkShadow,
                        Color highlight)

创建一个 BasicArrowButton的箭头画在指定的方向，用指定的颜色。

参数

direction -箭头的方向；一个 SwingConstants.NORTH， SwingConstants.SOUTH， SwingConstants.EAST或 SwingConstants.WEST

background -按钮的背景颜色

shadow -阴影的颜色

darkShadow -黑暗阴影的颜色

highlight -亮点的颜色

从以下版本开始：

一点四

BasicArrowButton

public BasicArrowButton(int direction)

创建一个 BasicArrowButton的箭头画在指定的方向。

参数

direction -箭头的方向；一个 SwingConstants.NORTH， SwingConstants.SOUTH， SwingConstants.EAST或 SwingConstants.WEST

方法详细信息

getDirection

public int getDirection()

返回箭头的方向。

setDirection

public void setDirection(int direction)

设置箭头的方向。

参数

direction -箭头的方向；一对 SwingConstants.NORTH， SwingConstants.SOUTH， SwingConstants.EAST或 SwingConstants.WEST

paint

public void paint(Graphics g)

从阶级复制的描述： JComponent

由摆动调用组件调用。应用程序不应调用 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。

重写：

paint 方法重写，继承类 JComponent

参数

g -其中 Graphics背景画

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)

getPreferredSize

public Dimension getPreferredSize()

返回的 BasicArrowButton首选大小。

重写：

getPreferredSize 方法重写，继承类 JComponent

结果

首选大小

另请参见：

JComponent.setPreferredSize(java.awt.Dimension)， ComponentUI

getMinimumSize

public Dimension getMinimumSize()

返回的 BasicArrowButton最小尺寸。

重写：

getMinimumSize 方法重写，继承类 JComponent

结果

最小尺寸

另请参见：

JComponent.setMinimumSize(java.awt.Dimension)， ComponentUI

getMaximumSize

public Dimension getMaximumSize()

返回的 BasicArrowButton最大尺寸。

重写：

getMaximumSize 方法重写，继承类 JComponent

结果

最大尺寸

另请参见：

JComponent.setMaximumSize(java.awt.Dimension)， ComponentUI

isFocusTraversable

public boolean isFocusTraversable()

返回箭头按钮是否应该得到焦点。 BasicArrowButtons被用作一个如 JScrollBar和 JComboBox复合组件的子组件。由于复合材料构件通常得到的焦点，这种方法是重写返回 false。

重写：

isFocusTraversable 方法重写，继承类 Component

结果

false

另请参见：

Component.setFocusable(boolean)

paintTriangle

public void paintTriangle(Graphics g,
                          int x,
                          int y,
                          int size,
                          int direction,
                          boolean isEnabled)

画一个三角形。

参数

g - Graphics画

x的X坐标

y的Y坐标

size -三角形的大小绘制

在这 direction方向画箭头；一个 SwingConstants.NORTH， SwingConstants.SOUTH， SwingConstants.EAST或 SwingConstants.WEST

isEnabled是否被启用的箭
