BasicArrowButton (Java Platform SE 6) - JavaTM 2 Platform Standard Edition 6.0 API 规范中文版
javax.swing.plaf.basic
类 BasicArrowButton
java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JButton
javax.swing.plaf.basic.BasicArrowButton
- 所有已实现的接口:
- ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants
- 直接已知子类:
- MetalScrollButton
public class BasicArrowButton
- extends JButton
- implements SwingConstants
一个 JButton 对象,它绘制朝某个基本方向的缩放箭头。
警告:此类的序列化对象将与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储,或适用于在运行相同 Swing 版本的应用程序之间进行 RMI(Remote Method Invocation,远程方法调用)。从 1.4 版本开始,已在 java.beans
包中添加了支持所有 JavaBeansTM 长期存储的功能。请参见 XMLEncoder

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

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

- 箭头的方向;SwingConstants.NORTH
、SwingConstants.SOUTH
、SwingConstants.EAST
或 SwingConstants.WEST
之一
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。

、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
