方法详细信息

getDirection

public int getDirection()

setDirection

public void setDirection(int dir)

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。一般而言，不应在分配给边框的 insets 区域绘制组件及其子组件。子类可以始终只重写此方法。只想特殊化 UI（外观）委托的 paint 方法的子类应该只重写 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()

从类 JComponent 复制的描述

如果 preferredSize 已设置为非 null 值，则返回该值。如果 UI 委托的 getPreferredSize 方法返回非 null 值，则返回该值；否则服从该组件的布局管理器。

覆盖：

类 JComponent 中的 getPreferredSize

返回：

preferredSize 属性的值

另请参见：

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

getMinimumSize

public Dimension getMinimumSize()

从类 JComponent 复制的描述

如果已将最低大小设置为非 null 值，则返回该值。如果 UI 委托的 getMinimumSize 方法返回非 null 值，则返回该值；否则服从该组件的布局管理器。

覆盖：

类 JComponent 中的 getMinimumSize

返回：

minimumSize 属性的值

另请参见：

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

getMaximumSize

public Dimension getMaximumSize()

从类 JComponent 复制的描述

如果已将最大大小设置为非 null 值，则返回该值。如果 UI 委托的 getMaximumSize 方法返回非 null 值，则返回该值；否则服从该组件的布局管理器。

覆盖：

类 JComponent 中的 getMaximumSize

返回：

maximumSize 属性的值

另请参见：

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

isFocusTraversable

public boolean isFocusTraversable()

从类 Component 复制的描述

返回此 Component 是否可以成为焦点所有者。

覆盖：

类 Component 中的 isFocusTraversable

返回：

如果此 Component 是可以获得焦点的，则返回 true；否则返回 false

另请参见：

Component.setFocusable(boolean)

paintTriangle

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