字段详细信息

direction

protected int direction
箭头的方向。SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一。

构造方法详细信息

BasicArrowButton

public BasicArrowButton(int direction,
                        Color background,
                        Color shadow,
                        Color darkShadow,
                        Color highlight)
创建一个在指定方向上绘制其箭头并具有指定颜色的 BasicArrowButton。

参数：
direction - 箭头的方向；SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一
background - 按钮的背景色
shadow - 阴影的颜色
darkShadow - 黑阴影的颜色
highlight - 高亮显示的颜色
从以下版本开始：
1.4

BasicArrowButton

public BasicArrowButton(int direction)
创建一个在指定方向上绘制其箭头的 BasicArrowButton。

参数：
direction - 箭头的方向；SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一
方法详细信息

getDirection

public int getDirection()
返回箭头的方向。

参数：
direction - 箭头的方向；SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一

setDirection

public void setDirection(int dir)
设置箭头的方向。

参数：
direction - 箭头的方向；SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一

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。一般来说，不应在分配给边框的 insets 区域绘制组件及其子组件。子类可以始终重写此方法。只想特殊化 UI（外观）委托的 paint 方法的子类只需重写 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)

getPreferredSize

public Dimension getPreferredSize()
返回 BasicArrowButton 的首选大小。

覆盖：
类 JComponent 中的 getPreferredSize
返回：
首选大小
另请参见：
JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

getMinimumSize

public Dimension getMinimumSize()
返回 BasicArrowButton 的最小大小。

覆盖：
类 JComponent 中的 getMinimumSize
返回：
最小大小
另请参见：
JComponent.setMinimumSize(java.awt.Dimension), ComponentUI

getMaximumSize

public Dimension getMaximumSize()
返回 BasicArrowButton 的最大大小。

覆盖：
类 JComponent 中的 getMaximumSize
返回：
最大大小
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取焦点。BasicArrowButton 用作复合组件（如 JScrollBar 和 JComboBox）的子组件。因为通常是复合组件获取焦点，所以重写此方法以返回 false。

覆盖：
类 Component 中的 isFocusTraversable
返回：
false
另请参见：
Component.setFocusable(boolean)

paintTriangle

public void paintTriangle(Graphics g,
                          int x,
                          int y,
                          int size,
                          int direction,
                          boolean isEnabled)
绘制一个三角形。

参数：
g - 要在其上进行绘制的 Graphics
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 之一
isEnabled - 是否已启用绘制箭头
