问题 I'm trying to display travel connections in a TableView. So far that works like a charm. Now I'm kinda stuck trying to get details of a connection to be displayed in between table rows. This should happen on selecting a table item. The problem is, that the details are in a different format than the connections I'm displaying. So I would need to put a panel between two table rows. Is this at all possible? 回答1: The "proper" way to do this would be to create a custom skin for TableRow and use a

Each "model" is populated from a plist file, that loads its contents into an array in the -viewDIdLoad, later everything is passed to the

问题 I have been using JavaFx's tableview to display a huge amount of data from the database. The table is like 150+ columns and millions of rows. I can handle the rows by getting the data in chunks and implementing paginations(link). But the no of columns is also an area of concern. It takes a lot of time to paint the data and does not update the data when I change the values in the model(ref). I dont have a predefined data structure and so the method at this is not useful.
