JavaFX2.2 TableView:How to make a table cell be edited without mouse click?

Question

Hi,
I've encounter a problem with editable table cells. I'm using the TableView in my project just as the Tutorial on Oracle (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm).
According to it, I use the setCellFactory method to reimplement the table cell as a text field with the help of the TextFieldTableCell class. However, I found the steps is a little complex to get to the point where the cell can be edited:
1.Let the table cell be selected by using direction key.
2.Press “Enter” to converts the cell to a text filed so that it is ready to be edited.
3.Clicking in the text field allows the contents to be edited
The problem is step 3, that you must use the mouse to click before you can input data in this table cell.
So, is there a solution to avoid step 3? That is the text field allows the data inputting when you just press “Enter”(step 2).
By the way, English is not my native language. Hope I have made myself clear.

Hi,
You need to pass the focus to the text field when the startEditing event occurs. In the class that extends TableCell you use for cellFactory:
public void startEdit() {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
* put focus on the textfield so user can directly typed on it
Runnable r = new Runnable() {
@Override
public void run() {
getGraphic().requestFocus();
Platform.runLater(r);
}
