This code snippet creates a B4J window with a table view that displays data from a SQLite table named "user". The code connects to the database, retrieves the data from the "user" table, and populates the table view with the retrieved data. The LoadTableData
subroutine executes a query to fetch all rows from the "user" table and adds each row as an item in the table view. The TableView1_ItemClick
event handler can be used to handle item click events in the table view.
Please note that you need to have the necessary B4J libraries and SQLite driver set up in your project for this code to work properly.
