创建HTML编辑器
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage stage) {
HTMLEditor htmlEditor = new HTMLEditor();
htmlEditor.setPrefHeight(245);
Scene scene = new Scene(htmlEditor);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
HTML内容
要将内容设置为HTMLEditor类，请使用setHtmlText方法。
htmlEditor.setHtmlText(INITIAL_TEXT);import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage stage) {
HTMLEditor htmlEditor = new HTMLEditor();
htmlEditor.setPrefHeight(245);
String INITIAL_TEXT = "Lorem ipsum dolor sit "
+ "amet, consectetur adipiscing elit. Nam tortor felis, pulvinar "
+ "aliquam sagittis gravida eu dolor. Etiam sit amet ipsum "
+ "sem.";
htmlEditor.setHtmlText(INITIAL_TEXT);
Scene scene = new Scene(htmlEditor);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
格式
我们可以使用此字符串中的HTML标记为最初渲染的内容应用特定的格式。
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage stage) {
HTMLEditor htmlEditor = new HTMLEditor();
htmlEditor.setPrefHeight(245);
String INITIAL_TEXT = "Lorem ipsum dolor sit "
+ "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "
+ "<UL><li>a</li><li>a</li><li>a</li></UL>"
+ "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "
+ "sem.";
htmlEditor.setHtmlText(INITIAL_TEXT);
Scene scene = new Scene(htmlEditor);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
获取HTML内容
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage stage) {
HTMLEditor htmlEditor = new HTMLEditor();
htmlEditor.setPrefHeight(245);
String INITIAL_TEXT = "Lorem ipsum dolor sit "
+ "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "
+ "<UL><li>a</li><li>a</li><li>a</li></UL>"
+ "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "
+ "sem.";
htmlEditor.setHtmlText(INITIAL_TEXT);
Button showHTMLButton = new Button("Produce HTML Code");
showHTMLButton.setOnAction((ActionEvent arg0) -> {
System.out.println(htmlEditor.getHtmlText());
});
VBox vbox = new VBox();
vbox.getChildren().addAll(htmlEditor,showHTMLButton);
Scene scene = new Scene(vbox);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
