关键技术和技术难点

1.实现页面切换

在QT的ui界面使用stack widget
在实现时调用函数

  1. ui->stackedWidget->setCurrentIndex(0);

2.读取存储用户输入并输出至表格中

ui界面设置LineEdit，实现时在确认按钮的槽函数中调用函数ui->lineEdit_6->text();读取输入，存入链表。
ui设置tablewidget，输出时调用ui->tablewidget->setItem(row,col,new QTableWidgetItem(""));设置表格信息。

3.链表类的实现

实现见上一条

4.错误信息设置

包括查找、删除不存在的节点，对空链表删除的信息提示

5.子窗口实现彩蛋设计
