构造方法详细信息

MetalScrollButton

public MetalScrollButton(int direction,
                         int width,
                         boolean freeStanding)

构造一个 MetalScrollButton的实例。

参数

direction - 方向

width - 宽度

freeStanding - 独立的价值

方法详细信息

setFreeStanding

public void setFreeStanding(boolean freeStanding)

设置独立的价值。

参数

freeStanding - 自由 freeStanding价值

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repaint 。

这种方法实际上委托绘画的工作，三个受保护的方法： paintComponent ， paintBorder ，并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。 一个只想要专门化UI（外观和感觉）的子类，委托的paint方法应该只是覆盖paintComponent 。

重写：

paint在 BasicArrowButton

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()

描述从类复制： BasicArrowButton

返回 BasicArrowButton的首选大小。

重写：

getPreferredSize在 BasicArrowButton

结果

优选尺寸

另请参见：

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

getMinimumSize

public Dimension getMinimumSize()

描述从类复制： BasicArrowButton

返回 BasicArrowButton的最小大小。

重写：

getMinimumSize在 BasicArrowButton

结果

最小尺寸

另请参见：

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

getMaximumSize

public Dimension getMaximumSize()

描述从类复制： BasicArrowButton

返回 BasicArrowButton的最大大小。

重写：

getMaximumSize在 BasicArrowButton

结果

最大尺寸

另请参见：

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

getButtonWidth

public int getButtonWidth()

返回按钮的宽度。

结果

按钮的宽度
