如何在Jtable某一列添加日历控件button

代码如下：自定义tableModel和TableCellRenderer，根据自己需求适当修改

import java.awt.BorderLayout

import java.awt.Color

import java.awt.Component

import java.awt.Dimension

import java.awt.event.MouseAdapter

import java.awt.event.MouseEvent

import java.io.File

import javax.swing.BorderFactory

import javax.swing.ImageIcon

import javax.swing.JButton

DateDropFrame extends JFrame

给year和month添加一个ItemListener来实时计算指定年和月中有多少天就可以了.

代码是用Swing写的,不过看你的图,不像是Swing界面.

/**

* Create the frame.

*/

public DateDropFrame() {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)

setBounds(100, 100, 450, 300)

contentPane = new JPanel()

contentPane.setBorder(new EmptyBorder(5, 5, 5, 5))

contentPane.setLayout(new FlowLayout(FlowLayout.LEFT))

final JComboBox year = new JComboBox()

year.setModel(new DefaultComboBoxModel(getModel(start, end)))

contentPane.add(year)

final JComboBox month = new JComboBox()

month.setModel(new DefaultComboBoxModel(getModel(1, 12)))

contentPane.add(month)

final JComboBox day = new JComboBox()

contentPane.add(day)

year.addItemListener(new ItemListener() {

public void itemStateChanged(ItemEvent e) {

setDay(year, month, day)

}

})

month.addItemListener(new ItemListener() {

public void itemStateChanged(ItemEvent e) {

setDay(year, month, day)

}

})

setDay(year, month, day)

setContentPane(contentPane)

}

/**

* calculate days in select month &year

*/

private void setDay(JComboBox year, JComboBox month, JComboBox day) {

int y = Integer.parseInt((String) year.getSelectedItem())

int m = Integer.parseInt((String) month.getSelectedItem())

Calendar c = Calendar.getInstance()

c.set(Calendar.YEAR, y)

c.set(Calendar.MONTH, m - 1)

int days = c.getActualMaximum(Calendar.DAY_OF_MONTH)

day.setModel(new DefaultComboBoxModel(getModel(1, days)))

}

/**

* get String array [start, end]

*/

private String[] getModel(int start, int end) {

String[] m = new String[end - start + 1]

for (int i = 0i <m.lengthi++) {

m[i] = String.valueOf(i + start)

}

return m

}
