javafx：默认情况下对TableView排序

Question

I'm developing a small game that has a highscore list displayed by a javafx TableView . I've created a subclass HighscoreTableView extends TableView which is a TableView node that automatically creates the TableColumns I need and fills them with data on construction.

I want that table to be sorted by a default column on initialisation. I've added the following code lines:

duration.setSortType(TableColumn.SortType.DESCENDING);
this.getSortOrder().add(duration);
duration.setSortable(true);
this.sort();

where duration is the TableColumn that should define the sorting. Of course, it's added to the TableView . But when I create a new instance of that HighscoreTableView , it remains unsorted by default, until the user clicks on one of the column headers. This is unexpected, since this question , this question and this question say it should work that way. Any ideas?

Further information for reproduction: The HighscoreTableView class is used by a HighscoreStage extends Stage class, which contains a TabPane with four Tabs. Each Tab contains a HighscoreTableView with different data taken from a static Data object. The data model is a class HighscoreEntry , an ObservableList of them gets added to the HighscoreTableView s. My full code is available here .

Answer 1

You are calling sort() before any data is loaded. Instead you should call it each time after adding/changing data to the table view. Also you can use SortedList with appropriate comparator to wrap your original backing list. Than all changes will be automatically propagated to view.
