Center the text in the textfield

Question

Is there a way to center the text in the text field? Specially vertically.

Answer 1

It seems that when a new text is set, the start position of the text is not recomputed, as the following example demonstrates. Initially all text fields are aligned correctly. But when you then hit the update button, all textfields are updated with a new, longer text which shows the problem. All texts seem to start at the same position which was computed for the previous text and not the recomputed new position for the new text. To temporarily work around this problem, you can reset the alignment of the text fields and then set it back to your desired value. This forces a recomputation of the text start position.
package textfield.alignment;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TextFieldAlignment extends Application {
     TextField lText;
     TextField cText;
     TextField rText;
     public static void main(String[] args) {
          launch(args);
     @Override
     public void start(Stage stage) {
          lText = new TextField("left");
          lText.setAlignment(Pos.BASELINE_LEFT);
          cText = new TextField("center");
          cText.setAlignment(Pos.BASELINE_CENTER);
          rText = new TextField("right");
          rText.setAlignment(Pos.BASELINE_RIGHT);
          Button btn = new Button("update");
          btn.setOnAction(new EventHandler<ActionEvent>() {
               @Override
               public void handle(ActionEvent t) {
                    lText.setText("updated left");
                    cText.setText("updated center");
                    rText.setText("updated right");
//                    applyWorkaround();
          VBox root = new VBox();
          root.getChildren().addAll(lText, cText, rText, btn);
          stage.setScene(new Scene(root, 200, 300));
          stage.show();
     void applyWorkaround() {
          lText.setAlignment(Pos.CENTER);
          lText.setAlignment(Pos.BASELINE_LEFT);
          cText.setAlignment(Pos.CENTER);
          cText.setAlignment(Pos.BASELINE_CENTER);
          rText.setAlignment(Pos.CENTER);
          rText.setAlignment(Pos.BASELINE_RIGHT);          
}
