JavaFX 使 listView 单元格无法选择

Question

我找不到使 ListViews 的单元格无法选择的方法。

我有一个带有自定义单元格的 ListView，里面有一些按钮，我想制作它，这样您就无法选择单元格，但可以使用按钮。我想像listView.setSelectable; 或listView.setSelectionModel(SelectionMode.NONE); 这样的东西，但没有这样的东西！

即使没有不允许选择任何项目的现有选择模型实现，您也可以自己实现一个：

public class EmptySelectionModel<T> extends MultipleSelectionModel<T> {

    // since this list is empty and unmodifiable, it's safe to use it as
    // both index and item list
    private ObservableList emptyList = FXCollections.emptyObservableList();

    @Override
    public ObservableList<Integer> getSelectedIndices() {
        return emptyList;
    }

    @Override
    public ObservableList<T> getSelectedItems() {
        return emptyList;
    }

    // just do nothing instead of selecting/unselecting anything

    @Override
    public void selectIndices(int index, int... indices) {
    }

    @Override
    public void selectAll() {
    }

    @Override
    public void selectFirst() {
    }

    @Override
    public void selectLast() {
    }

    @Override
    public void clearAndSelect(int index) {
    }

    @Override
    public void select(int index) {
    }

    @Override
    public void select(T obj) {
    }

    @Override
    public void clearSelection(int index) {
    }

    @Override
    public void clearSelection() {
    }

    @Override
    public void selectPrevious() {
    }

    @Override
    public void selectNext() {
    }

    @Override
    public boolean isSelected(int index) {
        return false; // no items are selected
    }

    @Override
    public boolean isEmpty() {
        return true; // selection is always empty
    }

}

listView.setSelectionModel(new EmptySelectionModel<>());
