我将以下代码与java 8
using一起使用javaFx
。
import javafx.application.Application;
import javafx.event.*;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.*;
import javafx.scene.web.*;
import javafx.stage.Stage;
@SuppressWarnings("all")
public class Highlighter extends Application {
private boolean marked;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
final WebView webView = new WebView();
final WebEngine engine = webView.getEngine();
engine.load("http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html");
final TextField searchField = new TextField("light");
searchField.setPromptText("Enter the text you would like to highlight and press ENTER to highlight");
searchField.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent actionEvent) {
if (engine.getDocument() != null) {
highlight(
engine,
searchField.getText()
);
}
}
});
final Button highlightButton = new Button("Highlight");
highlightButton.setDefaultButton(true);
highlightButton.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent actionEvent) {
searchField.fireEvent(new ActionEvent());
}
});
final Button markedButton = new Button("Mark it");
markedButton.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent actionEvent) {
marked = true;
}
});
markedButton.setCancelButton(true);
HBox controls = new HBox(10);
controls.getChildren().setAll(
highlightButton,
markedButton
);
VBox layout = new VBox(10);
layout.getChildren().setAll(searchField, controls, webView);
searchField.setMinHeight(Control.USE_PREF_SIZE);
controls.setMinHeight(Control.USE_PREF_SIZE);
controls.disableProperty().bind(webView.getEngine().getLoadWorker().runningProperty());
searchField.disableProperty().bind(webView.getEngine().getLoadWorker().runningProperty());
primaryStage.setScene(new Scene(layout));
primaryStage.show();
webView.requestFocus();
}
private void highlight(WebEngine engine, String text) {
engine.executeScript("$('body').removeHighlight().highlight('" + text + "')");
}
}
我的问题是我想添加一个显示marked status
页面的标签。
我尝试简单地将 a 添加Label label = new Label("Marked: " + marked)
到controls
,但这不起作用。
有什么建议可以在我的代码中添加标签以显示marked status
?
感谢您的回复!
