字段详细信息

direction

protected int direction

方向箭头。 一个SwingConstants.NORTH ， SwingConstants.SOUTH ， SwingConstants.EAST或SwingConstants.WEST 。

构造方法详细信息

BasicArrowButton

public BasicArrowButton(int direction,
                        Color background,
                        Color shadow,
                        Color darkShadow,
                        Color highlight)

创建一个 BasicArrowButton ，其箭头以 BasicArrowButton的方向绘制并具有指定的颜色。

参数

direction - 方向箭头; 之一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 - highlight的颜色

从以下版本开始：

1.4

BasicArrowButton

public BasicArrowButton(int direction)

创建一个 BasicArrowButton ，其箭头在 BasicArrowButton的方向绘制。

参数

direction - 箭头的方向; 之一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; 中的一个SwingConstants.NORTH ， SwingConstants.SOUTH ， SwingConstants.EAST或SwingConstants.WEST

paint

public void paint(Graphics g)

描述从类别复制： JComponent

由Swing调用来绘制组件。 应用程序不应直接调用paint ，而应使用repaint方法来调度组件进行重画。

这种方法实际上委托绘画的工作，三个受保护的方法： paintComponent ， paintBorder和paintChildren 。 它们按列出的顺序调用，以确保孩子出现在组件本身的顶部。 一般来说，组件及其孩子不应在分配给边界的插页区域中绘制。 子类可以像以前一样覆盖此方法。 一个子类，只是想要专门的UI（外观和感觉）委托的paint方法应该覆盖paintComponent 。

重写：

paint在 JComponent

参数

g - 要绘画的 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)

getPreferredSize

public Dimension getPreferredSize()

返回的优选大小 BasicArrowButton 。

重写：

getPreferredSize在 JComponent

结果

优选尺寸

另请参见：

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

getMinimumSize

public Dimension getMinimumSize()

返回 BasicArrowButton的最小大小。

重写：

getMinimumSize在 JComponent

结果

最小尺寸

另请参见：

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

getMaximumSize

public Dimension getMaximumSize()

返回 BasicArrowButton的最大大小。

重写：

getMaximumSize在 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获得焦点。 BasicArrowButton用作复合组件的子组件，如JScrollBar和JComboBox 。 由于复合组件通常得到焦点，所以该方法被覆盖以返回false 。

重写：

isFocusTraversable在 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)

涂三角形

参数

g - Graphics画

x - x坐标

y - y坐标

size - 要绘制的三角形的大小

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

isEnabled - whether or not the arrow is drawn enabled
