Question

我有TableView实例，有些列包含ComboBox。

private TableView<ScheduleLecture> tableSchedule;
private TableColumn<ScheduleLecture, DayOfWeek> colDay;

private void initialize() {
colDay.setCellValueFactory(new PropertyValueFactory<>("day"));
colDay.setCellFactory(ComboBoxTableCell.forTableColumn(DayOfWeek.values()));

我需要在关注时扩展TableCell的ComboBox。

public void onTableMouseClicked(MouseEvent event) {
    if (tableSchedule.getEditingCell() == null) {
        int row = tableSchedule.getSelectionModel().getFocusedIndex();
        ObservableList<TablePosition> selectedCells = tableSchedule.getSelectionModel().getSelectedCells();
        if(selectedCells.size() == 0){
            return;
        }
        TableColumn col = selectedCells.get(0).getTableColumn();
        tableSchedule.edit(row, col);
        Object cellData = col.getCellData(0);
        if(cellData instanceof Enum){
            if(cellData instanceof DayOfWeek){
                //comboBox.show(); for cell [row, col.index]
            }
        }
    }
}

我是怎么做到的？
