count++;

我已将这个对象（即通过面板的表格）添加到我的 Jframe :: 中，如下所示
final Table T=new Table();
JPanel panel = new JPanel();
panel.setBounds(197, 5+T.getCount(), 114+T.getCount(), 104+T.getCount());
layeredPane.add(panel);
final JLabel lblNewLabel = new JLabel(T.getNAME());
panel.add(lblNewLabel);
handleDrag(panel);
table = new JTable();
table.setShowVerticalLines(false);
panel.add(table);
table.setModel(new DefaultTableModel(
new Object[][] {
{null, null},
{null, null},
{null, null},
{null, null},
},
new String[] {
"Name", "type"
}
) {
Class[] columnTypes = new Class[] {
String.class, Object.class
};
public Class getColumnClass(int columnIndex) {
return columnTypes[columnIndex];
}
boolean[] columnEditables = new boolean[] {
false, true
};
public boolean isCellEditable(int row, int column) {
return columnEditables[column];
}
我想添加一个鼠标侦听器，每当单击此表（对象）时，该表的名称应执行“ Console.writeline（Table.getNAME（））；” ::我想在对象时在控制台上打印对象的名称被点击。
我已通过 panel.setName(text); 为这些组件分配名称，即面板；
String name=new String();
mntmOneToOne.addMouseListener(new MouseAdapter()
{
@Override
public void mouseClicked(MouseEvent arg0)
{
int count = arg0.getClickCount();
if (count == 1)
{
// below Line is showing error as it doesnot know which panel is it about
name = panel.getName();
}
}
});
