I have two Buttons and two ComboBoxes . The width of buttons is unknown as the text depends on the language. ComboBoxes must stretch maximum, but they must always have same width. I mean that comboBox1.getWidth() must be equal to comboBox2.getWidth().

This is my code:

public class JavaFxTest7 extends Application {

    @Override
    public void start(Stage stage) {
        var button1 = new Button("Text with unknown length");
        var comboBox1 = new ComboBox<String>();
        comboBox1.setEditable(true);
        comboBox1.setMaxWidth(Double.MAX_VALUE);
        var toolBar1 = new ToolBar(comboBox1, button1);
        HBox.setHgrow(comboBox1, Priority.ALWAYS);

        var button2 = new Button("Another text with unknown length");
        var comboBox2 = new ComboBox<String>();
        comboBox2.setEditable(true);
        comboBox2.setMaxWidth(Double.MAX_VALUE);
        HBox.setHgrow(comboBox2, Priority.ALWAYS);
        var toolBar2 = new ToolBar(comboBox2, button2);

        Scene scene = new Scene(new VBox(toolBar1, toolBar2), 800, 200);
        stage.setScene(scene);
        stage.show();
    }

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

Could anyone say how to do it?
