paint

public void paint(Graphics g)

從類別 JComponent 複製的描述

由 Swing 調用，以繪製元件。應用程序不應直接調用 paint，而是應該使用 repaint 方法來安排重繪元件。

此方法實際上將繪製工作委託給三個受保護的方法：paintComponent、paintBorder 和 paintChildren。按列出的順序調用這些方法，以確保子元件出現在元件本身的頂部。一般來說，不應在分派給邊框的 insets 區域繪製元件及其子元件。子類別可以始終覆寫此方法。只想特殊化 UI（外觀）委託的 paint 方法的子類別只需覆寫 paintComponent。

覆寫：

類別 JComponent 中的 paint

參數：

g - 在其中進行繪製的 Graphics 上下文

另請參見：

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 的首選大小。

覆寫：

類別 JComponent 中的 getPreferredSize

返回：

首選大小

另請參見：

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

getMinimumSize

public Dimension getMinimumSize()

返回 BasicArrowButton 的最小大小。

覆寫：

類別 JComponent 中的 getMinimumSize

返回：

最小大小

另請參見：

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

getMaximumSize

public Dimension getMaximumSize()

返回 BasicArrowButton 的最大大小。

覆寫：

類別 JComponent 中的 getMaximumSize

返回：

最大大小

另請參見：

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

isFocusTraversable

public boolean isFocusTraversable()

返回箭頭按鈕是否應該獲取焦點。BasicArrowButton 用作復合元件（如 JScrollBar 和 JComboBox）的子元件。因為通常是復合元件獲取焦點，所以覆寫此方法以返回 false。

覆寫：

類別 Component 中的 isFocusTraversable

返回：

false

另請參見：

Component.setFocusable(boolean)

paintTriangle

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

繪製一個三角形。

參數：

g - 要在其上進行繪製的 Graphics

x - x 坐標

y - y 坐標

size - 要繪製的三角形的大小

direction - 繪製箭頭的方向；SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 之一

isEnabled - 是否已啟用繪製箭頭
