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
。

public BasicComboBoxRenderer()
方法详细信息 |

public Dimension getPreferredSize()
JComponent
复制的描述preferredSize
已设置为一个非 null
值,则返回该值。如果 UI 委托的 getPreferredSize
方法返回一个非 null
值,则返回该值;否则服从组件的布局管理器。
JComponent
中的 getPreferredSize
preferredSize
属性的值JComponent.setPreferredSize(java.awt.Dimension)
,
ComponentUI
public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus)
ListCellRenderer
复制的描述paint
方法来“呈现”单元格。如果由于列表单元格没有固定的大小而有必要计算该列表的尺寸,则调用此方法来生成一个可在其上调用 getPreferredSize
的组件。
ListCellRenderer
中的 getListCellRendererComponent
list
- 正在绘制的 JList。value
- 由 list.getModel().getElementAt(index) 返回的值。index
- 单元格索引。isSelected
- 如果选择了指定的单元格,则为 true。cellHasFocus
- 如果指定的单元格拥有焦点,则为 true。
JList
