How to rename tab's text on double click in JavaFX 2? - tabs

Question

I have a simple code to add tab(s) to a tabPane
#FXML
private void addNewWorkspaceTab(ActionEvent event) {
Tab workspaceTab = new Tab();
workspaceTab.setText("New Workspace");
tabpaneWorkspace.getTabs().addAll(workspaceTab);
tabpaneWorkspace.setTabClosingPolicy(TabPane.TabClosingPolicy.SELECTED_TAB);
}
By double left mouse click on a tab I would like to rename (by typing a new text) the selected tab: how can I do this?

Here is a solution for my question:
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TextField;
import javafx.scene.input.MouseEvent;
/**
*
* #author utente
*/
public class TabSetText {
public Tab createEditableTab(String text) {
final Label label = new Label(text);
final Tab tab = new Tab();
tab.setGraphic(label);
final TextField textField = new TextField();
label.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
if (event.getClickCount()==2) {
textField.setText(label.getText());
tab.setGraphic(textField);
textField.selectAll();
textField.requestFocus();
}
}
});
textField.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
label.setText(textField.getText());
tab.setGraphic(label);
}
});
textField.focusedProperty().addListener(new ChangeListener<Boolean>() {
#Override
public void changed(ObservableValue<? extends Boolean> observable,
Boolean oldValue, Boolean newValue) {
if (! newValue) {
label.setText(textField.getText());
tab.setGraphic(label);
}
}
});
return tab ;
}
}
