在QTableWidget中添加表格并读取为字符串
const_wss 人气:0注意:这只是一个demo,项目中用到利用QTableWidget创建表,表中包含各种控件,最后保存表中的内容到doc中,此demo完成了QTableWidget中表的创建,以及将表中内容转为字符串格式输出,字符串便于存储为doc。
关键点:1、读取列表中不同控件的内容,并转为字符串。首先获取QWidget类型,用QWidget->children().at(x)找到你这个QWidget中实际控件的位置,注意x的取值取决于你创建表的时候,往QWidget里边放置的内容顺序。
2、然后你要获取的控件是什么类型你就把1中获取的QWidget强转成什么类型,如:QDateEdit *dataedit=(QDateEdit*)(widget->children().at(1));
此时就可以将获取的控件转为字符串了。
基本功能介绍:
demo里创建了两个QTableWidget控件,左侧我测试添加单一类型QLineEdit,点击add即增加一行,点击save即输出列表内容,也就是以字符串的形式获取QTableWidget表中的内容(方便输出为doc文件)。
右侧我测试添加各种类型的数据,包括QDateEdit QComboBox等类型,同样点击增加增加一行,点击保存即输出表中内容字符串。
点击“add”或“增加”:
点击“save”或“保存”:
