类 AbstractColorChooserPanel

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JPanel
                  javax.swing.colorchooser.AbstractColorChooserPanel

所有已实现的接口：: ImageObserver, MenuContainer, Serializable, Accessible

public abstract class AbstractColorChooserPanel
extends JPanel
extends JPanel

这是用于颜色选取器的抽象超类。如果希望在 JColorChooser 中添加一个新的颜色选取器面板，请创建该类的子类。

警告：此类已序列化的对象将不再与以后的 Swing 版本兼容。当前的序列化支持适合在运行相同 Swing 版本的应用程序之间短期存储或 RMI。从 1.4 版开始，已在 java.beans 包中加入对所有 JavaBeans^TM 的长期存储支持。请参见 XMLEncoder。

构造方法详细信息

AbstractColorChooserPanel

public AbstractColorChooserPanel()

方法详细信息

updateChooser

public abstract void updateChooser()

在模型状态更改时自动调用。也可以由 installChooserPanel 来调用它，以便允许您设置选取器的初始状态。重写此方法以更新 ChooserPanel。

buildChooser

protected abstract void buildChooser()

建立一个新的选取器面板。

getDisplayName

public abstract String getDisplayName()

返回一个包含面板显示名称的字符串。

返回：: 显示面板的名称

getMnemonic

public int getMnemonic()

提供关于 KeyEvent.VK 常量的外观方面的提示，此常量可用作访问面板的助记符。返回值 <= 0 表明无助记符。

这里的返回值是一个提示，最终由外观来为此返回值赋予真实的含义。

此实现返回 0，表明 AbstractColorChooserPanel 不支持助记符，希望使用助记符的子类需要重写此方法。

返回：: 标识助记符的 KeyEvent.VK 常量；返回值 <= 0 表示无助记符
从以下版本开始：: 1.4
另请参见：: getDisplayedMnemonicIndex()

getDisplayedMnemonicIndex

public int getDisplayedMnemonicIndex()

提供关于 getDisplayName 中字符的索引在外观方面的提示，字符索引应以可视化的方式标识为助记符。如果 getMnemonic 返回值 > 0，外观应当只用助记符。

这里的返回值是一个提示，最终由外观来为此返回值赋予真实的含义。例如，外观希望在 JTabbedPane 中呈现每个 AbstractColorChooserPanel，然后进一步使用该返回值来为 getDisplayName 中的某个字符加下划线。

此实现返回 -1，表明 AbstractColorChooserPanel 不支持助记符，希望使用助记符的子类需要重写此方法。

返回：: 呈现助记符的字符索引；-1 表示不为该面板提供任何可视化标识符。
从以下版本开始：: 1.4
另请参见：: getMnemonic()

getSmallDisplayIcon

public abstract Icon getSmallDisplayIcon()

返回此面板的小图标。

返回：: 小显示图标

getLargeDisplayIcon

public abstract Icon getLargeDisplayIcon()

返回此面板的大显示图标。

返回：: 大显示图标

installChooserPanel

public void installChooserPanel(JColorChooser enclosingChooser)

将面板添加到选取器时被调用。如果要重写此方法，一定要确保调用 super。

参数：: enclosingChooser - 要添加的面板
抛出：: RuntimeException - 如果已安装了选取器面板

uninstallChooserPanel

public void uninstallChooserPanel(JColorChooser enclosingChooser)

从选取器中移除面板时被调用。如果要重写此方法，一定要确保调用 super。

getColorSelectionModel

public ColorSelectionModel getColorSelectionModel()

返回选取器面板正在编辑的模型。

返回：: 此面板正在编辑的 ColorSelectionModel 模型

getColorFromModel

protected Color getColorFromModel()

返回当前所选取的颜色。

返回：: 所选取的 Color

paint

public void paint(Graphics g)

绘制面板。

覆盖：: 类 JComponent 中的 paint

参数：: g - Graphics 对象
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)
