Question

In my JavaFX-program I use a TableCell where you can edit a value. Like shown at the examples on the JavaFX-page “Example”, I use this function to save the changes (function is set on TextField in edit Cell)

textField.setOnKeyReleased(new EventHandler<KeyEvent>() {
    @Override public void handle(KeyEvent t) {
    if (combo.match(t)) {
        commitEdit(textField.getText());
    } else if (t.getCode() == KeyCode.ESCAPE) {
        cancelEdit();
    }
 }

When using ENTER to leave the cell, the value is changed / saved, but how can I change / save the value, when leaving the cell by clicking in another cell? Actually the value is resetted.

Thanks

Listening to a change in focus on the TextField is one way.. I added a listener to the focusedProperty of the textField. The example from Oracle didn’t include this.
[edit – here is a link to another question that has a different approach UITableView – Better Editing through Binding? ]

private void createTextField() {
        textField = new TextField(getItem());
        textField.setMinWidth(this.getWidth() - this.getGraphicTextGap() * 2);

        // Detect a change in focus on the text field.. If we lose the focus we take appropriate action
        textField.focusedProperty().addListener(new ChangeListener<Boolean>() {
            public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
                if(!newValue.booleanValue())
                    commitEdit(textField.getText());
            }
        } );
        textField.setOnKeyReleased(new EventHandler<KeyEvent>() {
            @Override public void handle(KeyEvent t) {
                if (t.getCode() == KeyCode.ENTER) {
                    commitEdit(textField.getText());
                } else if (t.getCode() == KeyCode.ESCAPE) {
                    cancelEdit();
                }
            }
        });
    }
