[英]JavaFX MenuBar on Pane on Borderpane (top) flickers
I'm writing a program in Java and I'm using JavaFX for the GUI, using the MVC way. 我正在用Java编写程序,并且使用MVC方式将JavaFX用于GUI。
The structure of the view I'm talking about is as follow: 我正在谈论的视图结构如下:
The reason for this structure is because I want to keep my code clean & clear. 之所以采用这种结构,是因为我想保持代码的整洁。
Inside the TopPane I want only a menuBar. 在TopPane内部,我只需要一个menuBar。
I've added this as follow: 我添加了以下内容:
public class TopPane extends Pane {
private MenuBar menuBar;
public TopPane() {
initNodes();
layoutNodes();
}
private void initNodes() {
Menu[] menus = new Menu[3];
menus[0] = new Menu("File");
menus[1] = new Menu("Options");
menus[2] = new Menu("Help");
MenuItem[] menuItemsFile = new MenuItem[4];
menuItemsFile[0] = new MenuItem("New game");
menuItemsFile[1] = new MenuItem("Save game");
menuItemsFile[2] = new MenuItem("Load game");
menuItemsFile[3] = new MenuItem("Exit");
menus[0].getItems().addAll(menuItemsFile);
MenuItem options = new MenuItem("Options");
menus[1].getItems().add(options);
MenuItem help = new MenuItem("Help");
menus[2].getItems().add(help);
menuBar = new MenuBar();
menuBar.getMenus().addAll(menus);
}
private void layoutNodes() {
menuBar.setMinWidth(Double.MAX_VALUE);
menuBar.useSystemMenuBarProperty().set(true);
getChildren().add(menuBar);
}
public MenuBar getMenuBar() {
return menuBar;
}
}
In gameview I do the following: 在gameview中,我执行以下操作:
public class GameView extends BorderPane {
private TopPane topPane;
private LeftPane leftPane;
private PlayerView playerView; //centerpane
private RightPane rightPane;
public GameView() {
initNodes();
layoutNodes();
}
private void initNodes() {
topPane = new TopPane();
leftPane = new LeftPane();
playerView = new PlayerView();
rightPane = new RightPane();
}
private void layoutNodes() {
this.setStyle("-fx-background-color: #2a2a2a");
this.setTop(topPane);
Rectangle2D screenBounds = Screen.getPrimary().getVisualBounds();
double screenHeight = screenBounds.getHeight();
int topMargin = 25;
if (screenHeight >= 1050) {
topMargin = 150;
}
System.out.println(screenHeight);
setMargin(leftPane, new Insets(topMargin, 0, 0, 50));
this.setLeft(leftPane);
setMargin(playerView, new Insets(0, 0, 0, 25));
this.setCenter(playerView);
this.setRight(rightPane);
}
}
It shows the menubar succesfully but the problem is that when I click one of the menus, the menuItems just flickers and dissapear immediatly. 它成功显示了菜单栏,但是问题是,当我单击菜单之一时,menuItems会立即闪烁并消失。 I think this is because I extend topPane with Pane. 我认为这是因为我使用Pane扩展了topPane。 But without it couldn't work obviously, and if I extend from menuBar (and delete the variable Menubar), my rightPane & PlayerView won't be added to my GameView for some mysterious dark reason I couldn't figure out (yet) :) 但是如果没有它,就无法正常工作,并且如果我从menuBar扩展(并删除变量Menubar),由于某些我无法弄清的神秘黑暗原因,我的rightPane和PlayerView将不会添加到我的GameView中: )
Anybody able to help me? 有人可以帮助我吗? Thanks in advance! 提前致谢!
