我在JavaFX中创建了一个包含大量文本的Label
。
Label l1 = new Label("\t\tC-Mark and Attendance Calculator is a simple "
+ "software to find both the C-Mark and monthly attendance "
+ "of students. Inorder to use the features of this software,"
+ " user has to create an account for him first. Then he should "
+ "login using the username and password. He will be able to "
+ "perform all the operations then. Further details are mentioned"
+ " in the 'HELP' section in the user home page.");
l1.setWrapText(true);
l1.setTextAlignment(TextAlignment.JUSTIFY);
在这段代码中setWrapText(true)
不起作用。为什么?我怎样才能使它工作?
Label l1 = new Label("\t\tC-Mark and Attendance Calculator is a simple "
+ "software to find both the C-Mark and monthly attendance "
+ "of students. Inorder to use the features of this software,"
+ " user has to create an account for him first. Then he should "
+ "login using the username and password. He will be able to "
+ "perform all the operations then. Further details are mentioned"
+ " in the 'HELP' section in the user home page.");
l1.setWrapText(true);
l1.setTextAlignment(TextAlignment.JUSTIFY);
这是一个SSCCE:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.text.TextAlignment;
import javafx.stage.Stage;
public class WrappedLabelExample extends Application {
@Override
public void start(Stage primaryStage) {
Label l1 = new Label("\t\tC-Mark and Attendance Calculator is a simple "
+ "software to find both the C-Mark and monthly attendance "
+ "of students. Inorder to use the features of this software,"
+ " user has to create an account for him first. Then he should "
+ "login using the username and password. He will be able to "
+ "perform all the operations then. Further details are mentioned"
+ " in the 'HELP' section in the user home page.");
l1.setWrapText(true);
l1.setTextAlignment(TextAlignment.JUSTIFY);
StackPane root = new StackPane(l1);
root.setPadding(new Insets(10));
Scene scene = new Scene(root, 400, 400);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
结果
