JTable Boolean.class

import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.AbstractTableModel; import javax.swing.table.TableModel; class ColorTableModel extends AbstractTableModel { Object rowData[][] = { { "value1", Boolean.FALSE }, { "value1", Boolean.FALSE }, { "value1", Boolean.FALSE }, { "value1", Boolean.FALSE}, { "value1", Boolean.FALSE }, }; String columnNames[] = { "English", "Boolean" }; public int getColumnCount() { return columnNames.length; } public String getColumnName(int column) { return columnNames[column]; } public int getRowCount() { return rowData.length; } public Object getValueAt(int row, int column) { return rowData[row][column]; } public Class getColumnClass(int column) { return (getValueAt(0, column).getClass()); } public void setValueAt(Object value, int row, int column) { rowData[row][column] = value; } public boolean isCellEditable(int row, int column) { return (column != 0); } } public class EditableColorColumn { public static void main(String args[]) { JFrame frame = new JFrame("Editable Color Table"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); TableModel model = new ColorTableModel(); JTable table = new JTable(model); // TableColumn column = table.getColumnModel().getColumn(3); // column.setCellRenderer(renderer); // column.setCellEditor(editor); JScrollPane scrollPane = new JScrollPane(table); frame.add(scrollPane, BorderLayout.CENTER); frame.setSize(400, 150); frame.setVisible(true); } 

如果我勾选相应的行，我想得到第一列的值。 我已经阅读了很多关于此的内容，但我不能把它放到代码中。 你能编一个代码吗？

示例场景，当我勾选row1复选框时，它将是system.out.println() ，其结果为value1 。

Answer 1

您在AbstractTableModel实现setValueAt()无法触发将通知侦听器更改的事件：

 @Override public void setValueAt(Object value, int row, int column) { rowData[row][column] = value; fireTableCellUpdated(row, column); } 

一旦纠正， TableModelListener将看到每个更改。 尝试注释掉fireTableCellUpdated()行以查看差异。

此外：

• 应该仅在事件派发线程上构造和操作Swing GUI对象。

• 避免在Java Swing中使用set(Preferred|Maximum|Minimum)Size方法; setPreferredScrollableViewportSize()只是稍微危险一点。

Answer 2

您可以使用getSelectedRow（）来获取所选的行。 然后使用getValueAt（row，column），其中row是从getSelectedRow（）获得的值，column是您想要的列。 试试以下： –

int row=table.getSelectedRow();

String value=table.getValueAt(row, 0).toString();

其中0表示它将返回第一列的值。

Answer 3

如果只需要获取所选列的值，请尝试此操作

 table.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { int row = table.getSelectedRow(); System.out.println("Selected Row ; " + row ); System.out.println("Velue : " + model.getValueAt(row, 0)); } });
