JavaFX | TextFlow 类

原文:https://www.geeksforgeeks.org/javafx-textflow-class/

TextFlow 类是 JavaFX 的一部分。TextFlow 类旨在布局富文本。它可用于在单个文本流中布局多个文本节点。TextFlow 类扩展了窗格类。

类的构造函数:

TextFlow() :新建一个 TextFlow 对象。
TextFlow(Node… c) :用指定的节点创建一个新的 TextFlow 对象。

常用方法:

方法	说明
getLineSpacing()	返回文本流的行距
getTextAlignment()	返回文本流的文本对齐方式
设置行间距(双 s)	设置文本流的行距。
设置对齐(文本对齐 v)	设置文本流的文本对齐方式。

下面的程序说明了文本流类的使用:

Java program to create a TextFlow and add text object to it: In this program we will create a TextFlow named text_flow and two Text named text_1 and text_2. Set the fill and font using setFill() and setFont(). We will add the text to the text_flow using the getChildren().add() function. Add the text_flow to the scene and scene to the stage. Call the show() function to display the final results.

```java // Java program to create a TextFlow and // add text object to it . import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.; import javafx.scene.layout.; import javafx.stage.Stage; import javafx.event.ActionEvent; import javafx.scene.paint.; import javafx.scene.text.; import javafx.scene.web.; import javafx.scene.layout.; import javafx.scene.shape.*;

public class TextFlow_0 extends Application {

// launch the application     public void start(Stage stage)     {

try {

// set title for the stage             stage.setTitle("TextFlow");

// create TextFlow             TextFlow text_flow = new TextFlow();

// create text             Text text_1 = new Text("GeeksforGeeks\n");

// set the text color             text_1.setFill(Color.RED);

// set font of the text             text_1.setFont(Font.font("Verdana", 25));

// create text             Text text_2 = new Text("The computer science portal for geeks");

// set the text color             text_2.setFill(Color.BLUE);

// set font of the text             text_2.setFont(Font.font("Helvetica", FontPosture.ITALIC, 15));

// add text to textflow             text_flow.getChildren().add(text_1);             text_flow.getChildren().add(text_2);

// create a scene             Scene scene = new Scene(text_flow, 400, 300);

// set the scene             stage.setScene(scene);

stage.show();         }

catch (Exception e) {

System.out.println(e.getMessage());         }     }

// Main Method     public static void main(String args[])     {

// launch the application         launch(args);     } } ```
