【Java】在JTable中設置鼠標監聽器，點擊操作對應數據

最終效果

鼠標點擊JTable中任一數據，修改相應的信息。

確定點擊的行和列

 

package com.dao;

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JTable;

public class TableMethod extends BaseDAO{
	int rowww ;
	int colll ;
	public int getRowww() {
		return rowww;
	}
	public void setRowww(int rowww) {
		this.rowww = rowww;
	}
	public int getColll() {
		return colll;
	}
	public void setColll(int colll) {
		this.colll = colll;
	}
	/** 確定行和列*/
	public void TableRowCol(final JTable tJTable) {
        tJTable.setRowSelectionAllowed(true);//設置是否可以選擇此模型中的行
        tJTable.setColumnSelectionAllowed(true);//設置是否可以選擇此模型中的列
        tJTable.addMouseListener(new MouseAdapter()
        {
            public void mouseClicked(MouseEvent event)
            {
                    int row = tJTable.rowAtPoint(event.getPoint());
                    int col = tJTable.columnAtPoint(event.getPoint());
                    tJTable.setRowSelectionInterval(row, row);
                    tJTable.setColumnSelectionInterval(0, tJTable.getColumnCount()-1);
//                    tJTable.setColumnSelectionInterval(col, col);
                    setRowww(row);
                    setColll(col);
            }
        });
	}
}

 

 

在修改按鈕中設置監聽器

 

 

	private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
		// TODO add your handling code here:修改
		tm.TableRowCol(jTable1);
		if (tm.getColll()==0 && tm.getRowww()==0) {
			JOptionPane.showMessageDialog(null, "請先選擇顧客！", "修改顧客信息失敗", 0);
		} else {
			String username = (String)tableObjects()[tm.getRowww()][1];
			Manage_Adduser mAdduser = new Manage_Adduser(username);
			mAdduser.setVisible(true);   
		}
	}

其中

 

tableObjects數組是JTable的數據轉換得到的二維數組。
