我已经编写了以下方法来创建表，但是每次每次任务列表不同时都调用它，但是表无法更改表的值
public void displayAllTaskByProjectId(Task[] task) {
System.out.println("Success fully call");
/**
* The table to display tasks related to the selected project and timer
* for that
*/
tblTaskList = new JTable();
LOG.info(" get here");
int length;
DefaultTableModel dm = new DefaultTableModel(0, 0) {
private static final long serialVersionUID = 1L;
public Class getColumnClass(int column) {
return getValueAt(0, column).getClass();
};
public boolean isCellEditable(int row, int column) {
switch (column) {
case 5:
return true;
default:
return false;
}
};
};
dm.fireTableDataChanged();
String header[] = new String[] { "Prority", "Task Title", "Start",
"Pause", "Stop", "Statulses" };
dm.setColumnIdentifiers(header);
// Add image icon in table
ImageIcon imgStart = new ImageIcon("../../../../start.png");
ImageIcon imgStop = new ImageIcon("../../../../stop.png");
ImageIcon imgPause = new ImageIcon("../../../../pause.png");
length = task.length;
for (int count = 0; count < length; count++) {
dm.addRow(new Object[] { count, task[count].getTaskTitle() + count,
imgStart, imgPause, imgStop, "Active" });
}
tblTaskList.setModel(dm);
TableColumn tbcStatus = tblTaskList.getColumnModel().getColumn(5);
JComboBox cmbStatus = new JComboBox();
cmbStatus.setModel(new DefaultComboBoxModel(new String[] { "Active",
"Close", "Deactive", "Offline" }));
tbcStatus.setCellEditor(new DefaultCellEditor(cmbStatus));
tblTaskList.getColumnModel().getColumn(0).setMinWidth(0);
tblTaskList.getColumnModel().getColumn(0).setMaxWidth(0);
tblTaskList.getColumnModel().getColumn(1).setPreferredWidth(350);
tblTaskList.getColumnModel().getColumn(2).setPreferredWidth(35);
tblTaskList.getColumnModel().getColumn(3).setPreferredWidth(35);
tblTaskList.getColumnModel().getColumn(4).setPreferredWidth(25);
tblTaskList.getTableHeader().setReorderingAllowed(false);
tblTaskList.getTableHeader().setResizingAllowed(false);
tblTaskList.setBounds(93, 34, 614, 324);
jspTasklist = new JScrollPane(tblTaskList);
jspTasklist.setOpaque(false);
jspTasklist.setFocusTraversalPolicyProvider(true);
jspTasklist.setBounds(108, 34, 605, 335);
frmTaskList.getContentPane().add(jspTasklist);
}
请尽快给我解决我的问题
最佳答案
您应该只删除tblTaskList = new JTable（）;从displayAllTaskByProjectId函数和代码将正常工作。仅在初始化组件时才使用此行tblTaskList = new JTable（）
