How to remove JavaFX stage buttons (minimize, maximize, close)

Question

How to remove JavaFX stage buttons (minimize, maximize, close)? Can't find any according Stage methods, so should I use style for the stage? It's necessary for implementing Dialog windows like Error, Warning, Info.

Answer 1

If you want to disable only the maximize button then use :

stage.resizableProperty().setValue(Boolean.FALSE);

or if u want to disable maximize and minimize except close use

stage.initStyle(StageStyle.UTILITY);

or if you want to remove all three then use

stage.initStyle(StageStyle.UNDECORATED);

Answer 2

You just have to set a stage's style. Try this example:

package undecorated;

import javafx.application.Application;
import javafx.stage.StageStyle;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class UndecoratedApp extends Application {

    public static void main(String[] args) {
        Application.launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        primaryStage.initStyle(StageStyle.UNDECORATED);

        Group root = new Group();
        Scene scene = new Scene(root, 100, 100);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

When learning JavaFX 2.0 these examples are very helpful.
