インスタンス オブジェクトからメソッドを参照して、いくつかのボタンを作成しようとしています。柔軟性を得るために、この方法で行う必要があります (コンテキストに応じてツールバーにボタンを追加する)。私のプロジェクトは GluonFX プロジェクト (コンパイルに Gradle ファイルを使用するJavaFX + Gluon ) です。

これらのボタンの作成を担当する関数は次のとおりです。

public void postInit() {
    ToolbarVerticalCtrl toolbar = getRoot().getToolbarCtrl();
    ChronologyViewerCtrl viewer = ((ChronologyViewerCtrl) _tabControllersMap.get(TAB_PATIENT_CHRON_ID).getUserData());

    Image iconPlot = new Image(getClass().getResource("/ch/aardex/images/48px/button_plot.png").toExternalForm());
    toolbar.addNewButtonOnToolbar(new ImageView(iconPlot), i18n("title.chronology"), viewer::switchToPlot, false, true);
    // add calendar view button
    Image iconCalendar = new Image(getClass().getResource("/ch/aardex/images/48px/button_calendar.png").toExternalForm());
    toolbar.addNewButtonOnToolbar(new ImageView(iconCalendar), i18n("title.calendar"), viewer::switchToCalendar, false, false);
    // add patient details button
    Image iconDetails = new Image(getClass().getResource("/ch/aardex/images/48px/button_patient_details.png").toExternalForm());
    toolbar.addNewButtonOnToolbar(new ImageView(iconDetails), i18n("title.patientDetails"), this::openPatientDetailsTab, false, false);
    // add print report button
    Image iconPrint = new Image(getClass().getResource("/ch/aardex/images/48px/button_print.png").toExternalForm());
    toolbar.addNewButtonOnToolbar(new ImageView(iconPrint), i18n("title.printReport"), this::printPatientReport, false, false);
    // add print report button
    Image iconDelete = new Image(getClass().getResource("/ch/aardex/images/48px/button_delete.png").toExternalForm());
    toolbar.addNewButtonOnToolbar(new ImageView(iconDelete), i18n("title.deletePatient"), viewer::deletePatient, true, false);
}

ご覧のとおりviewer、タイプ ChronologyViewerCtrl で取得されたインスタンスです。インスタンスがnull ではありません

プロジェクトを実行すると、gradle ビルドから次のエラーが発生します (スタックトレースの最も重要な行を表示し、書式設定がひどいという理由だけで貼り付けを作成しました)。

スタックトレース => http://paste.ubuntu.com/16888255/

コントローラーで参照している関数は次のとおりです。

public void switchToCalendar(){
    String script = "pManager.hotSwitch( aardex.plugin.CalendarAdapter.prototype.type, pManager.plot.getScaleObj() );";
    execute(script);

    getRootTab().openTab(RootTabPaneCtrl.TAB_PATIENT_CHRON_ID);
}

public void switchToPlot(){
    String script = "pManager.hotSwitch( aardex.plugin.ChronologyAdapter.prototype.type, pManager.plot.getScaleObj() );";
    execute(script);

    getRootTab().openTab(RootTabPaneCtrl.TAB_PATIENT_CHRON_ID);
}

私は多くの投稿をチェックし、すべての.classファイルをクリアし(推測しますか?)、publicスコープを関数に設定しましたが、何も変わりませんでした。アイデア?私は夢中になっています。

ありがとうございました

私はgradleにあまり詳しくないので、何か間違っている(または廃止されている)場合はお知らせください、ありがとうございます!

私は最終的にこれらのメソッド参照をあきらめ、元の状態に戻しました。念のため、JDK を 8u91 に更新しましたが、メソッド参照やラムダ式さえも持たない別のクラスにエラーが影響しているようです。このクラスはメイン クラスであり、これがエラーです (738 行目)。

私が理解しているのは、存在しないretrolambdafunction が原因で Main クラスのバックポートに失敗したということです!checkLicence(LicenceBusiness, String)

助けてください、私は本当に立ち往生していて、何をすべきかわかりません。
