Javafx: Re-sorting a column in a TableView

Question

I have a TableView associated to a TreeView. Each time a node in the TreeView is selected, the TableView is refreshed with different data.

I am able to sort any col

Answer 1

You can also do this for 0 or more Sort-Columns:

List<TableColumn<Room, ?>> sortColumns = new LinkedList<>(rooms.getSortOrder());
// rooms.setItems(...)
rooms.getSortOrder().addAll(sortColumns);

The reason why you create a new LinkedList is that you don't wanna just point at rooms.getSortOrder() like this:

List<TableColumn<Room, ?>> sortColumns = rooms.getSortOrder();

because this way both rooms.getSortOrder() and sortColumns will become empty after you call rooms.setItems(...) which seems to clear the rooms.getSortOrder().

Answer 2

You can also use a SortedList.

SortedList<MatchTableBean> tableItems = new SortedList<>(
        observableList, Comparator.comparing(MatchTableBean::isMarker).reversed().thenComparing(MatchTableBean::getQueryRT));
    tableItems.comparatorProperty().bind(table.comparatorProperty());
    table.setItems(tableItems);

This way the table is sorted, even when the content changes or is completely replaced.
