java设计界面与按钮之间的连接方法

1、 清空按钮

privatevoid jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                        

        //清空数据

        DefaultTableModel dtm =(DefaultTableModel)jTable1.getModel();

         int row = jTable1.getSelectedRow();

         System.out.println(row);

         if(row==-1)

             row = 0;

         dtm.removeRow(row);

} 

2、 增加按钮

privatevoid jButton_AddActionPerformed(java.awt.event.ActionEvent evt) {                                           

       //增加数据

        String namestr =jTextField_Name.getText();

       String agestr =jTextField_Age.getText();

       String sexstr =jTextField_Sex.getText();

       String cardidstr =jTextField_CardID.getText();

       DefaultTableModel dtm =(DefaultTableModel)jTable1.getModel();

       Vector al = new Vector();

       al.add(namestr);

       al.add(sexstr);

       al.add(agestr);

       al.add(cardidstr);

       dtm.addRow(al);

    }  

3、 修改按钮

privatevoid jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                        

        // 修改

        int row = jTable1.getSelectedRow();

        if(row>-1){

            String namestr =jTextField_Name.getText();

            String agestr =jTextField_Age.getText();

            String sexstr =jTextField_Sex.getText();

            String cardidstr =jTextField_CardID.getText();

           

            jTable1.setValueAt(namestr, row,0);

            jTable1.setValueAt(sexstr, row, 1);

            jTable1.setValueAt(agestr, row, 2);

            jTable1.setValueAt(cardidstr, row, 3);

        }

    }     

4、 获取数据

privatevoid jTable1MouseClicked(java.awt.event.MouseEvent evt) {                                    

        //获取数据

        int row = jTable1.getSelectedRow();

        jTextField_Name.setText((String)jTable1.getValueAt(row,0));

       jTextField_Sex.setText((String)jTable1.getValueAt(row, 1));

       jTextField_Age.setText((String)jTable1.getValueAt(row, 2));

       jTextField_CardID.setText((String)jTable1.getValueAt(row, 3));

    }
