This service will then either attempt to - * save the file or run it with a helper app depending on what the - * mozilla mime database returns. - * - * nsIExternalHelperAppService then calls out to the nsIHelperAppDialog - * interface which handles the UI for the service. This is the interface - * which we have reimplemented. Therefore, with a major caveat, we have - * put a GNOME/GTK frontend on an unmodified mozilla backend. - * - * Now for the caveat. With respect to saving files to disk, the mozilla - * backend works exactly the same as it does in - * mozilla-the-browser. However, for dealing with helper apps, we do not - * use the mozilla backend at all. This is because we want to use the - * gnome-vfs database to retrieve helper-app info, rather than the - * mozilla helper app database. - * - * How it works: - * - * a) The user clicks on a link or follows a redirect to a file of a type - * that mozilla cannot handle. Mozilla passes the link to the - * ExternalHelperAppService which in turn calls the Show() method of - * nsIHelperAppDialog. - * - * b) In our implementation of Show() we first compare the passed mime - * type to epiphany's mime list. If the mime type is in the list, we then - * lookup the Action associated with the mime type. Currently, the - * possible mime-actions are: - * - * Save to Disk - * Run with Helper App - * Ask User - * - * The default action is Ask User, and if the mime-type is not in our - * list, this is what will be assumed. - * - * c) If Ask User is the chosen action, a dialog will be shown to the - * user allowing the user to choose from the other two possible actions - * as well as a checkbox to let the user set the default action to the - * chosen action for the future. - * - * d-1) The "Save to Disk" action. We first check epiphany preferences to - * see if the user wants to use the built-in mozilla downloader, gtm or - * a command-line executed downloader. - * - * d-2a) The built-in downloader. This action is handled by the mozilla - * backend. Our nsIHelperAppDialog does the same thing that the - * mozilla-the-browser one does, which is to call the SaveToDisk() method - * of nsIExternalHelperAppService. This in turn calls the - * PromptForSaveToFile() method of nsIHelperAppDialog putting the ball - * back in our court. - * - * d-2b) Now, if epiphany is configured to always ask for a download - * directory, it will pop up a file selector so that the user can select - * the directory and filename to save the file to. Otherwise, it will - * use epiphany's default download directory and proceed without - * interaction. - * - * d-2c) When PromptForSaveToFile() returns, nsIExternalHelperAppService - * will then call the ShowProgressDialog() method of - * nsIHelperAppDialog. This progress dialog, obviously, tracks the - * progress of the download. It is worth noting that mozilla starts the - * actual download as soon as the user clicks on the link or follows the - * redirect. While the user is deciding what action to take, the file is - * downloading. Often, for small files, the file is already downloaded - * when the user decides what directory to put it in. The progress dialog - * does not appear in these cases. Also, we currently have a small - * problem where our progress dialog times the download from the point - * the dialog appears, not from the time the download starts. This is due - * to the timestamp that is passed to us is just plain weird, and I - * haven't worked out how to turn it into a useable time. The fact that - * the download starts early means that the file is actually downloaded - * to a temp file and only at the end is it moved to it's final location. - * - * d-3a) The two external downloader options. These options are - * handled completely by epiphany. The first thing that we do is call the - * Cancel() method of nsIExternalHelperAppService to cancel the mozilla - * download. We then pass the url to our own LaunchExternalDownloader() - * method. This method will ask for a download directory as appropriate - * as with the "Save to disk" action. - * - * d-3b) Finally, depending on whether GTM or a command line handler was - * selected in prefs, the external handler will be called with the url - * passed and the directory selected. - * - * e-1) The "Run with Helper App" action. This action is currently only - * working with a minimal implementation. First, we explicitly call - * ShowProgressDialog() so the user knows that the file is being - * downloaded. We also need this so that we only run the helper after the - * file is completely downloaded. The file will download to temp location - * that it would be moved from if the action was "Save to Disk". We have - * to call ShowProgressDialog() ourselves because we are not using - * mozilla's helper mechanism which would usually make the call for us. - * - * e-2) If there is a default helper app in our mime database and alwaysAsk - * is false, epiphany will run the default helper automatically. Otherwise it - * will pop up a helper chooser dialog which lists the helpers that gnome-vfs - * knows about as well as providing a GnomeFileEntry to allow the user to - * select and arbitrary application. The default value of the GnomeFileEntry - * is the helper stored in our database if one exits. - * - * f) General notes. We cannot use this infrastructure to override - * native mozilla types. mozilla will attempt to render these types and - * never call out to us. We are at the end of the chain as the handler of - * last resort, so native and plugin types will never reach us. This also - * means that a file with an incorrect mime-type ( eg: .tar.bz2 marked as - * text/plain ) will be incorrectly rendered by mozilla. We cannot help - * this. - * - * Despite the apparent user-side similarity with explicit downloads by - * a shift-click or context-menu item, there is actually none at all. - * Explicit downloads are handled by the nsIStreamTransfer manager which - * we use as is. Currently the progress dialog for the stream transfer - * manager is un-overridable, so it appears in XUL. This will change in - * due course. - * - * Matt would like the modifiy the progress dialog so each file currently - * being downloaded becomes a clist entry in a master dialog rather than - * causing a separate progress dialog. a lot of progress dialogs gets - * really messy. - */ - #ifdef HAVE_CONFIG_H #include "config.h" #endif @@ -153,76 +27,26 @@ #include "MozillaPrivate.h" #include "nsCOMPtr.h" -#include "nsISupportsArray.h" -#include "nsIServiceManager.h" - #include "nsString.h" #include "nsIURI.h" #include "nsIURL.h" -#include "nsIChannel.h" #include "nsILocalFile.h" -#include "nsIPrefService.h" -#include "nsIDOMWindow.h" -#include "nsIDOMWindowInternal.h" #include "nsIMIMEInfo.h" -#include "ephy-embed-shell.h" #include "ephy-prefs.h" #include "eel-gconf-extensions.h" -#include "ephy-glade.h" -#include "ephy-string.h" -#include "ephy-gui.h" -#include "ephy-file-helpers.h" - -#include <gtk/gtkentry.h> -#include <gtk/gtktogglebutton.h> -#include <gtk/gtkprogress.h> -#include <gtk/gtkoptionmenu.h> -#include <gtk/gtkdialog.h> -#include <gtk/gtkmessagedialog.h> -#include <libgnome/gnome-exec.h> -#include <libgnome/gnome-i18n.h> -#include <libgnome/gnome-config.h> -#include <libgnome/gnome-util.h> + #include <libgnomevfs/gnome-vfs-mime.h> #include <libgnomevfs/gnome-vfs-utils.h> #include <bonobo/bonobo-i18n.h> class GContentHandler;
