Control for displaying multiline text?

2019-02-04 00:08发布

I need to display a multiline, read-only text - which control can be used for that? It should only dislay the text, like a Label does, however Label does not support multiline?

Thanks for any hint :-)

Text class also available. A good explanation in this answer label-and-text-differences-in-javafx Basically use Text for where you're not getting input, otherwise Label is better.

You can display multi-line read-only text in a Label.

If the text has \n (newline) characters in it, then the label will wrap to a new line wherever the newline character is.

If the label has wrapText set to true and there is not enough space to display a single line of text, then the label will wrap the text to a new line.


If you want text in different styles, then, if using JavaFX 2, place multiple labels in a FlowPane or, if you are using Java 8+, place the labels in a TextFlow component.

Produced by the following code:

import javafx.scene.Scene;

import javafx.application.Application;
import javafx.scene.control.Label;
import javafx.scene.image.*;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class LoveMeNot extends Application {

  public static void main(String[] args) throws Exception { launch(args); }

  @Override public void start(final Stage stage) throws Exception {
    Label label = new Label(WORDS);
    label.setWrapText(true);
    label.setStyle("-fx-font-family: \"Comic Sans MS\"; -fx-font-size: 20; -fx-text-fill: darkred;");

    ImageView image = new ImageView(IMAGE);
    image.setOpacity(0.3);

    StackPane layout = new StackPane();
    layout.setStyle("-fx-background-color: mistyrose; -fx-padding: 10;");
    layout.getChildren().setAll(image, label);

    stage.setTitle("Love Me Not");
    stage.setScene(new Scene(layout));
    stage.show();
  }

  // creates a triangle.
  private static final String WORDS = 
    "Love not me for comely grace,\n" +
    "For my pleasing eye or face,\n" +
    "Nor for any outward part,\n" +
    "No, nor for my constant heart,\n" +
    "For these may fail, or turn to ill.\n" +
    "So thou and I must sever.\n" +
    "Keep therefore a true woman’s eye,\n" +
    "And love me still, but know not why,\n" +
    "So hast thou the same reason still\n" +
    "To doat upon me ever.";

  private static final Image IMAGE = 
    new Image("http://icons.iconarchive.com/icons/artdesigner/gentle-romantic/256/rose-icon.png");
}

Try running the above program and resizing the window to see the effect of the \n new line values in the label's text as well as the wrapText property on the label. Vary the wrapText setting from true to false to see the difference between having wrapText switched on and off.

If you set a max width you want for your Label, then you set setWrapText to true so it displays the text multiline:

Label label = new Label("Your long text here");
label.setMaxWidth(180);
label.setWrapText(true);

You can also use Text to appear in multiline, by setting wrappingWidthProperty according to your needs.

Text text = new Text();
text.wrappingWidthProperty().set(345);

In this code, I have set max width to 345.0 ,So When the text's size reaches beyond 345 pixels will be wrapped to next Line.

If the text has \n (newline) characters in it, then the label will place wrap to a new line wherever the newline character is.

It not works when you set text from FXML file as well as from visual FXML editor.
