Question

我已从他们的官方网站下载并安装了处理IDE，然后我按照如何将库导入eclipse的说明进行操作。我将core.jar，gluegen-rt.jar和jogl-all.jar添加到路径中。我有下面的代码，我试图运行，但是当我进入运行菜单时，没有任何运行选项。我只看到＆＃39;运行配置＆＃39;。我有什么遗失的吗？

public class myCamera extends MainMenu{

    private ImageView mImageView;
    private Bitmap mImageBitmap;
    static final String BITMAP_STORAGE_KEY = "viewbitmap";
    static final String IMAGEVIEW_VISIBILITY_STORAGE_KEY = "imageviewvisibility";

    public static final int MEDIA_TYPE_IMAGE = 1;
    public static final int MEDIA_TYPE_VIDEO = 2;

    protected static final int ACTION_TAKE_PHOTO_B = 1;
    protected static final int ACTION_TAKE_PHOTO_S = 2;

    protected int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = MEDIA_TYPE_IMAGE;
    protected Uri fileUri;

    protected String mCurrentPhotoPath;

    protected static final String JPEG_FILE_PREFIX = "IMG_";
    protected static final String JPEG_FILE_SUFFIX = ".jpg";

    private static final String CAMERA_DIR = "/dcim/";

    protected String getAlbumName() {

    }

    }

    protected void setCurrentPath(String mCurrentPhotoPath){
        this.mCurrentPhotoPath=mCurrentPhotoPath;

自处理3起，PApplet不再延长Applet（更多信息here）。换句话说，您不能再将草图作为applet运行。

您必须重新放入main方法并将其作为应用程序运行。

如果您真的想要作为applet运行，则必须创建自己的扩展Applet或JApplet的类，然后将Processing组件添加到该组中。这可能是相当复杂的，加上applet现在几乎已经死了，所以你可能会更好地部署为一个应用程序 - 甚至更好，就像使用Processing.js的JavaScript一样。

作为旁注，您不必依赖eclipse自动检测运行配置。您应该能够进入运行配置并自己创建一个。这对于这个特定情况不起作用，但是对于“幕后”的东西更加舒适并不是一个坏主意，所以这样的情况不那么令人困惑。
