コマンドラインアプリケーションからJavaFXクリップボードへのアクセス？

Question

これはニュービーから愚かな質問であるかもしれないので、私と一緒にくる。これが私がしたことです：

import javafx.scene.input.Clipboard;
import javafx.scene.input.ClipboardContent;

import javax.sound.sampled.Clip;

public class Main {
    public static void main(String[] args) {
        final Clipboard clipboard = Clipboard.getSystemClipboard();
        final ClipboardContent content = new ClipboardContent();
        content.putHtml("<b>Some bold html</b>");
        clipboard.setContent(content);
    }
}

.

次のエラーが発生しました：

GUIをすべて揃えずにJavaFX Cliboardにアクセスすることは可能ですか？

Answer 1

私はなぜあなたがこれをやりたいのかという問題を無視します...

コメント内で指摘されている場合は、JavaFXクリップボードにアクセスするためにFXアプリケーションスレッドを起動する必要があります。ただし、実際にはStageを任意の時点で表示する必要はありません。

次のコンパイルと実行：

import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.input.Clipboard;
import javafx.scene.input.ClipboardContent;
import javafx.stage.Stage;

public class ClipboardTest extends Application {

    @Override
    public void start(Stage primaryStage) {
        final Clipboard clipboard = Clipboard.getSystemClipboard();
        final ClipboardContent content = new ClipboardContent();
        content.putHtml("<b>Some bold html</b>");
        clipboard.setContent(content);

        Platform.exit();
    }

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