I have textfield that containing a value and that value should be Right alignment.
When i run the application it display the text left alignment but i set the Right alignment. and problem with 3rd textfield.
After clicking the update button it works fine.
So may i know why it is behave different.
Code:
import java.io.File;
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.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.FileChooser;
import javafx.stage.Stage;
public class TextFieldAlignment extends Application {
TextField rText;
File file;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage stage) {
rText = new TextField("updated right1 updated right2 updated right3 updated right4");
rText.setAlignment(Pos.CENTER_RIGHT);
Button btn = new Button("update");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent t) {
rText.setText("updated right1 updated right2 updated right3 updated right4");
// applyWorkaround();
}
});
final Label labelFile = new Label();
Button btn2 = new Button();
btn2.setText("Open FileChooser'");
btn2.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
FileChooser fileChooser = new FileChooser();
//Set extension filter
FileChooser.ExtensionFilter extFilter = new FileChooser.ExtensionFilter("AVI files (*.exml)", "*.exml");
fileChooser.getExtensionFilters().add(extFilter);
//Show open file dialog
file = fileChooser.showOpenDialog(null);
// rText.setText(file.getPath());
}
});
VBox root = new VBox();
root.getChildren().addAll(rText, btn, btn2);
stage.setScene(new Scene(root, 200, 300));
stage.show();
}
}
Put the setalignment and settext after you add the TextField to the Scene.

Node objects may be constructed and modified on any thread as long they are not yet attached to a Scene. An application must attach nodes to a Scene, and modify nodes that are already attached to a Scene, on the JavaFX Application Thread.
