Question

我正在扩展javafx.stage.Popup以显示弹出消息。整个应用程序在Windows和Ubuntu上运行良好，但在Mac Popups上，当应用程序全屏时，在当前阶段后面。我尝试过使用z-index，.toFront（），设置所有者窗口等等。但弹出窗口从未出现过！同样的问题是javafx.stage.FileChooser。由于应用必须始终全屏，解决方案是什么？

编辑：在另一个页面中，文本字段的光标全屏闪烁，但未收到键入的键！全屏幕出现 ONLY ！如果我丢失全屏，则文本字段会收到键入的键。相当讨厌:(请建议我是否应该提交错误或其他内容

我已经找到弹出窗口的解决方法，但DirectoryChooser / FileChooser仍然存在问题。

这是扩展Popup的类：

public class PopupDisplay extends Popup
{
String Title=new String("Information");
String Prompt=new String("Prompt Text");
@FXML
private AnchorPane anchorMain;
@FXML
private Label lblTitle=new Label();
@FXML
private Font x1;
@FXML
private Label lblPrompt=new Label();
@FXML
private Button btnOk;
@FXML
private GridPane gridMain;
@FXML
private HBox hboxTitle;
static PopupDisplay instance;
private ColorDxDesktop application;
public void show(Stage stage, String titleKey,String promptKey, Locale enLocale)
{
    AnchorPane root;
    FXMLLoader loader=new FXMLLoader();
    ResourceBundle rb;

    Prompt=promptKey;
    Title=titleKey;
    try
    {
        loader.setLocation(getClass().getResource("/com/sc/colordx/resources/"));
        rb=ResourceBundle.getBundle("com.sc.colordx.resources.lang.Popup",application.getLocale());

        loader.setResources(rb);
        PopupController.prompt=Prompt;
        PopupController.title=Title;

        root = (AnchorPane)loader.load(getClass().getResource("/com/sc/colordx/presentation/Popup.fxml").openStream());
        getScene().setRoot(root);
        PopupController popupController=loader.getController();



        Rectangle2D screenBounds = Screen.getPrimary().getVisualBounds();
        root.setPrefWidth(application.getStage().getWidth());
        root.setPrefHeight(application.getStage().getHeight());
        Node n=root.getChildren().get(0);
        n.setLayoutX(screenBounds.getWidth()/2.5);
        n.setLayoutY((screenBounds.getHeight()/2.5));
        //root.toFront();

        show(stage);


    } 
    catch (IOException ex) 
    {
        ex.printStackTrace();
    }
}


public static PopupDisplay getInstance()
{
    return instance;
}
@FXML
private void hide(MouseEvent event) 
{
    this.hide();
}
public void showInProgress()
{
    PopupController.showInProgress();


}

这是Popup的FXML：

Answer 1

在MAC中运行JavaFx应用程序时，我使用Popup获得了同样的东西，所以我所做的是使用initStyle(StageStyle.UTILITY);创建了新的Stage（虚拟/不可见，高度和宽度= 0）并将弹出窗口与此绑定。每次我需要显示弹出窗口时，我都会使用dummyStage.show();和popup.toFront();，这样就会在mac中处理我的问题。

Popup仅在Mac上落后于舞台，但在全屏幕上不在Windows / Linux上
