我不知道我是否真正理解您的问题,但是如果您有两个屏幕,为什么要循环显示屏幕?为什么不使用与屏幕相关的信息在位置二/索引之一ObservableList?我发布了一个示例应用程序,演示如何在第二台显示器上全屏显示。
import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.geometry.Rectangle2D;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Screen;
import javafx.stage.Stage;
/**
*
* @author blj0011
*/
public class JavaFXApplication257 extends Application
{
@Override
public void start(Stage primaryStage)
{
ObservableList<Screen> screens = Screen.getScreens();//Get list of Screens
Button btn = new Button();
btn.setText("Full Screen - Screen 1");
btn.setOnAction((ActionEvent event) -> {
Rectangle2D bounds = screens.get(0).getVisualBounds();
primaryStage.setX(bounds.getMinX());
primaryStage.setY(bounds.getMinY());
primaryStage.setFullScreen(true);
//primaryStage.setWidth(bounds.getWidth());
//primaryStage.setHeight(bounds.getHeight());
});
Button btn2 = new Button();
btn2.setText("Full Screen - Screen 2");
btn2.setOnAction((ActionEvent event) -> {
if (screens.size() > 0) {
Rectangle2D bounds = screens.get(1).getVisualBounds();
primaryStage.setX(bounds.getMinX());
primaryStage.setY(bounds.getMinY());
primaryStage.setFullScreen(true);
//primaryStage.setWidth(bounds.getWidth());
//primaryStage.setHeight(bounds.getHeight());
}
});
StackPane root = new StackPane();
root.getChildren().add(new VBox(btn, btn2));
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
launch(args);
}
}
