如何为JTable列添加JXDatepicker [英] How to Add a JXDatepicker for a JTable column

问题描述

我正在使用JTable。在那里我有一个日期列，当我点击单元格时，我需要使一个JXDatePicker出现，以便我可以从中选择一个日期。

有人可以显示我怎么办？

谢谢！等待一个答案..

解决方案

你应该可以使用 DatePickerCellEditor 这是一个 CellEditor ，使用 JXDatePicker 作为编辑器组件。例如：

  TableColumn dateColumn = table.getColumnModel（）。getColumn（columnIndex）; 
 dateColumn.setCellEditor（new DatePickerCellEditor（））; 
  

这是一个演示表：

  import java.util.Date; 
 
 import javax.swing.JFrame; 
 import javax.swing.JScrollPane; 
 import javax.swing.JTable; 
 import javax.swing.SwingUtilities; 
 import javax.swing.table.TableColumn; 
 
 import org.jdesktop.swingx.table.DatePickerCellEditor; 
 
 public class DateColumnDemo {
 
 private static void createAndShowGUI（）{
 JFrame frame = new JFrame（DateColumnDemo）; 
 frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）; 
 
 JTable table = new JTable（new Object [] [] {{1，new Date（）}}，
 new Object [] {Id，Time ）; 
 
 TableColumn dateColumn = table.getColumnModel（）。getColumn（1）; 
 dateColumn.setCellEditor（new DatePickerCellEditor（））; 
 
 JScrollPane scrollPane = new JScrollPane（table）; 
 
 frame.add（scrollPane）; 
 frame.pack（）; 
 frame.setVisible（true）; 
} 
 
 public static void main（String args []）{
 SwingUtilities.invokeLater（new Runnable（）{
 public void run（）{
 createAndShowGUI（）; 
} 
}）; 
} 
} 
  

I'm using a JTable. There I have a Date column, where I need to make a JXDatePicker appear when I click on a cell so that I can select a date from it.

Can someone show me how to do this?

Thanks! waiting for an answer..

解决方案

You should probably use DatePickerCellEditor, which is a CellEditor using a JXDatePicker as editor component. For example:

TableColumn dateColumn = table.getColumnModel().getColumn(columnIndex);
dateColumn.setCellEditor(new DatePickerCellEditor());

Here is a demo table:

import java.util.Date;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
import javax.swing.table.TableColumn;

import org.jdesktop.swingx.table.DatePickerCellEditor;

public class DateColumnDemo {

    private static void createAndShowGUI() {
        JFrame frame = new JFrame("DateColumnDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JTable table = new JTable(new Object[][] { { "1", new Date() } },
                new Object[] { "Id", "Time" });

        TableColumn dateColumn = table.getColumnModel().getColumn(1);
        dateColumn.setCellEditor(new DatePickerCellEditor());

        JScrollPane scrollPane = new JScrollPane(table); 

        frame.add(scrollPane);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String args[]) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}
