Personal loan inquiry window

Enter the borrower's code, press Enter or click OK, and the window will display all the borrower's loan information. If there is no borrower in the system, or the borrower has not borrowed a book, the window will not display any information. If you select the query by keyword option, you will enter the keyword query window.

In the initial state, the window displays the summary information of all books. If you want to see the specific information of a book, double-click the summary information of the book. By inputting keywords, users can make both fuzzy and accurate queries. If the query result is only one book, the system will directly display the specific information of the book. When accurate query is realized, the system will directly display the specific information of the book. If there are no books in the stack, no information will be displayed in the window. At the same time, the system also supports multi-keyword query.
