说明：  使用复选框显示给定的一组整数，选中一些，单击“全选”按钮，选中所有复选框；单击“对象选择”按钮，将多个选中整数显示在文本行数组中；在文本行中输入整数，单击“求和”按钮，将各文本行中的非空字符串转换成整数，再计算和并显示结果。若字符串不嫩转换成整数，采用对话库提示忽略它。
(Use the check box to display a given set of integers. Select some, click the "select all" button to select all check boxes; click the "object selection" button to display multiple selected integers in the text line array; enter the integer in the text line, and click the "sum" button to convert the non empty string in each text line into an integer, and then calculate and display the result. If the string is not converted to an integer, the dialog library prompt is used to ignore it.)
