How to make JavaFX text wrap work?
提问by Radu Stefan Popescu
I can't for the life of me make JavaFX wrap text. Instead my boxes get the size of the Text.
我一辈子都不能让 JavaFX 换行。相反，我的盒子得到了Text.
This is my main:
这是我的主要内容：
BorderPane main = FXMLLoader.load(getClass().getResource("main.fxml"));
primaryStage.setTitle("D394");
primaryStage.setScene(new Scene(main, 1000, 500));
primaryStage.getScene().getStylesheets().add("main.css");
primaryStage.show();
And this is my main.fxml. It's pretty big, sorry for that.
这是我的 main.fxml。它很大，对不起。

This is how it ends up lookingsetPrefWidthof the text does nothing
这就是它最终查看setPrefWidth文本的方式
Making the HBoxes smaller does make the text wrap, but it ends up on top of text from the other HBoxes.
使HBoxes 变小确实会使文本换行，但它最终位于其他HBoxes的文本之上。
What I want is for my text to wrap to the width of the HBoxes which should be at the same size as the parent actual size.
我想要的是让我的文本环绕HBoxes的宽度，该宽度应该与父实际大小相同。
My controller doesn't do anything in terms of styling and layout, and my .css doesn't do anything.
我的控制器在样式和布局方面没有做任何事情，而我的 .css 没有做任何事情。
I'm using java8.

You can use the wrappingWidthPropertyto define the wrapping width in pixels.
您可以使用wrappingWidthProperty来定义以像素为单位的环绕宽度。
You can use it in a binding:
您可以在绑定中使用它：
textID.wrappingWidthProperty().bind(tabPane.widthProperty());
This binds the mentioned property to the width of the TabPane. Note: Binding to the HBoxor the VBoxwill not work, as their width is the actual width of the Text(the HBoxis resized to the width of the Textand the VBoxis resized to the width of the HBox).
这将上述属性绑定到TabPane. 注：绑定到HBox或VBox将无法正常工作，因为它们的宽度的实际宽度Text（将HBox被调整至的宽度Text和VBox被调整至的宽度HBox）。

I have had this similar need in a simple dialog box. The root of the dialog box is a 2x2 GridPane. Each row contains an HBox that spans both columns. I use a Label to display a message in the HBox in row 0. To wrap the text I use the following: Label label = new Label(message); label.setWrapText(true);
我在一个简单的对话框中也有过类似的需求。对话框的根是一个 2x2 GridPane。每行包含一个跨越两列的 HBox。我使用标签在第 0 行的 HBox 中显示一条消息。要包装文本，我使用以下内容： Label label = new Label(message); label.setWrapText(true);
Then, of course, you add the label to the HBox. For your example, perhaps all you need to do is change Text to Label and this will work.
然后，当然，您将标签添加到 HBox。对于您的示例，也许您需要做的就是将 Text 更改为 Label ，这将起作用。
If you are using SceneBuilder you can go into the properties tab of the Label and click the WrapText checkbox.
如果您使用的是 SceneBuilder，您可以进入标签的属性选项卡并单击 WrapText 复选框。
