JavaFX: what is the best way to display a simple message?
提问by ceklock
In my application I need to display a warning/info message, but I don't know a simple way to do that because there is no JOptionPane or similar component on JavaFX.
在我的应用程序中，我需要显示一条警告/信息消息，但我不知道一种简单的方法来做到这一点，因为 JavaFX 上没有 JOptionPane 或类似的组件。
There is a Popup class, but you have to set many parameters to get a decent layout/position/background color/etc for a simple message... So I want to know if there is a simple, already implemented component to display messages, maybe in a third party library if JavaFX does not offer anything decent.
有一个 Popup 类，但是您必须设置许多参数才能为简单的消息获得合适的布局/位置/背景颜色/等......所以我想知道是否有一个简单的，已经实现的组件来显示消息，如果 JavaFX 不提供任何体面的东西，则可能在第三方库中。
Thanks in advance for any help/hints.
提前感谢您的任何帮助/提示。

ControlsFX is JavaFX 8 so I can't use it, and the other alternatives are almost the same level of complexity of what I was going to do. So I implemented my own methods to display an info/warning message using a Popup.
ControlsFX 是 JavaFX 8，所以我无法使用它，其他替代方案的复杂程度几乎与我要做的相同。所以我实现了我自己的方法来使用Popup显示信息/警告消息。
Here is the source code of what I implemented. Just some tweaks to show the Popup centered on the window, use CSS and hide when the user clicks on it.
这是我实现的源代码。只需进行一些调整即可显示以窗口为中心的弹出窗口，使用 CSS 并在用户单击它时隐藏。
public static Popup createPopup(final String message) {
final Popup popup = new Popup();
popup.setAutoFix(true);
popup.setAutoHide(true);
popup.setHideOnEscape(true);
Label label = new Label(message);
label.setOnMouseReleased(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent e) {
popup.hide();
}
});
label.getStylesheets().add("/css/styles.css");
label.getStyleClass().add("popup");
popup.getContent().add(label);
return popup;
}
public static void showPopupMessage(final String message, final Stage stage) {
final Popup popup = createPopup(message);
popup.setOnShown(new EventHandler<WindowEvent>() {
@Override
public void handle(WindowEvent e) {
popup.setX(stage.getX() + stage.getWidth()/2 - popup.getWidth()/2);
popup.setY(stage.getY() + stage.getHeight()/2 - popup.getHeight()/2);
}
});
popup.show(stage);
}
CSS:
CSS：
.popup {
-fx-background-color: cornsilk;
-fx-padding: 10;
-fx-border-color: black;
-fx-border-width: 5;
-fx-font-size: 16;
}
The pop-up message:

With Java 8u40 and upwards, you don't need to worry. It has JavaFX Dialogs.
使用 Java 8u40 及更高版本，您无需担心。它有JavaFX 对话框。

Just as simple as:
就这么简单：
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Information Dialog");
alert.setHeaderText("Look, an Information Dialog");
alert.setContentText("I have a great message for you!");
alert.showAndWait();
