Visualizing a Set with JTable in Java Swing?

I would stick with using a List since reliable ordering is fairly important in the backing for a table. Failing this you could use a sorted set such as a TreeSet.

Determine how you want the threads ordered and create a copy of the set in a list that is ordered correctly. Use that list for the model. When the set changes refresh your list with a newly ordered data.

SetValueAt uses only a specific data element, also fireTableCellUpdated(row, col);. – platzhirsch Apr 7 at 15:41 @Platz, You would refresh your model and call model. FireTableDataChanged(); or you would just build a new model and call setModel() on JTable.

Set does not provide a method to get an Object through a index. You should use a List to do what you want. Or iterate over the elements until the index passed by parameter into the 'int row' (Avoid this solution).

A table is inherently displaying a list, the underlying data model is typically a Vector of Vectors or an Object array. So in this case, you need to convert your Set into a List (so you need two data structures that stay in sync), and you need reasonable random access - a small Set may be fine to iterate over and find things, but anything of significant size is going to be an issue, as the JTable will ask often under certain circumstances.

Whats the relationship between a JTable, TableModel and TableData. I can show my data in a JTable without a problem, but when I want to filter while my app is running, the JTable is not showing me data changes. My TableModel implementations typically sit on an ArrayList to allow for efficient random access performance.

However, ArrayList's remove(int) implementation looks fairly inefficient as it involves making a System. JTable + TableModel cache fetch event for lazy instantiation? You are using a JTable with a custom TableModel to view the contents of some collection located in a database or on the network or whatever.

I have a JTable used to store numbers. I really only use the table for viewing/sorting. I would like to create a table with the constructor method JTable(TableModel).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
