Swing增加下拉列表框

在表格的一列中Swing增加下拉列表框，首先獲得列表對象，在設(shè)置表列編輯，將下拉列表框作為默認(rèn)列編輯對象設(shè)置到表列編輯對象中

importjava.awt.BorderLayout;  
importjava.awt.Dimension;  
 
importjavax.swing.JFrame;  
importjavax.swing.JPanel;  
importjavax.swing.JScrollPane;  
importjava.awt.Rectangle;  
importjavax.swing.JTable;  
importjavax.swing.table.TableColumn;  
importjavax.swing.DefaultCellEditor;  
importjavax.swing.JComboBox;  
importjavax.swing.JCheckBox;  
 
publicclassJComboBoxSecondextendsJFrame{  
JPanelcontentPane;  
JScrollPanejScrollPane1=newJScrollPane();  
Object[][]objContent={{"Tom","Hanks","Java","24","true"},{"Ben","John",  
"Java","25","true"},{"Michael","Fred","Java","26","true"},  
{"Steve","Bell","Java","27","true"},  
{"Jim","Lan","Java","29","true"}  
};  
Object[]objHead={"名字","姓氏","技能","年齡","是否屬實(shí)"};  
JTablejTable1=newJTable(objContent,objHead);  
JComboBoxjComBo=newJComboBox();  
JCheckBoxjCheck=newJCheckBox("");  
publicJComboBoxSecond(){  
try{  
setDefaultCloseOperation(EXIT_ON_CLOSE);  
jbInit();  
}catch(Exceptionexception){  
exception.printStackTrace();  
}  
}  
 
/**  
*Componentinitialization.  
*  
*@throwsjava.lang.Exception  
*/  
privatevoidjbInit()throwsException{  
contentPane=(JPanel)getContentPane();  
contentPane.setLayout(null);  
setSize(newDimension(467,401));  
setTitle("FrameTitle");  
jScrollPane1.setBounds(newRectangle(11,20,442,337));  
jComBo.addItem("Java");  
jComBo.addItem("Orcale");  
jComBo.addItem("Linux");  
jComBo.addItem("Unix");  
jComBo.addItem("C#");  
 
TableColumntableCol=jTable1.getColumnModel().getColumn(2);  
tableCol.setResizable(false);  
TableColumntableColCheck=jTable1.getColumnModel().getColumn(4);  
tableCol.setCellEditor(newDefaultCellEditor(jComBo));  
tableColCheck.setCellEditor(newDefaultCellEditor(jCheck));  
contentPane.add(jScrollPane1);  
jScrollPane1.getViewport().add(jTable1);  
}  
} 

以上是Swing增加下拉列表框，希望對大家有用
