How to get selected TableCell in JavaFX TableView

javafxjavafx-8

I am looking for a way to get the selected cell of a TableView control. Note that I don't just want the cell value, I want an actual TableCell object. One would expect that the method:

tableView.getSelectionModel().getSelectedCells().get(0)

does just that, but it returns a TablePosition object, which gives you row and column information, but I don't see a way to get TableCell object from that.

The reason I need this is because I want to respond to a key press, but attaching an event filter to TableCell does not work (probably because it is not editable). So I attach it to TableView, but then I need to get the currently selected cell.

EDIT: For future readers: DO NOT mess with TableCell objects, except in cell factory. Use the TableView the way designers intended, or you will be in lot of trouble. If you need data from multiple sources in single table, it is better to make a new class that aggregates all the data and use that as a TableView source.

I just posted an answer that uses this code to edit a Cell. I don't think you can get a reference to the actual table cell as that's internal to the table view.

tp = tv.getFocusModel().getFocusedCell();
tv.edit(tp.getRow(), tp.getTableColumn());

Your method also returns a TablePosition so you can use that as well.

You can achieve this by adding a KeyListener to your textField. Try adding the following code to your createTextField()

textField.setOnKeyPressed(new EventHandler<KeyEvent>() {
   @Override
   public void handle(KeyEvent t) {
       if (t.getCode() == KeyCode.ENTER) {
           commitEdit(Integer.parseInt(textField.getText()));
       } else if (t.getCode() == KeyCode.ESCAPE) {
           cancelEdit();
       } else if (t.getCode() == KeyCode.TAB) {
           commitEdit(Integer.parseInt(textField.getText()));
           TableColumn nextColumn = getNextColumn(!t.isShiftDown());
           if (nextColumn != null) {
               getTableView().edit(getTableRow().getIndex(), nextColumn);
           }
       }
   }
});

There are a few more things that you will have to take care of. For a complete example, please follow

Java – Getting java.lang.ClassNotFoundException: javax.servlet.ServletContext in JUnit

You have a single xml file for your ApplicationContext in this file there is a <mvc:annotation-driven /> tag. This tag loads different web related resources (view resolvers, handler mappings etc.) and as such requires the servlet api to be available.

You already should have the servlet api on your classpath as a provided dependency in maven.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Next to that you might want to remove the <mvc:annotation-driven /> tag and put it in a seperate configuration file. This is also a tag which should (in general speaking) be loaded by the DispatcherServlet. (I assume here the applicationContext.xml is, as default, loaded by the ContextLoaderListener).
