## Prerequisites

ThunarxMenuProvider requires GObject.

## Includes

    #include <thunarx/thunarx.h>

## Description

The ThunarxMenuProvider interface is implemented by extensions which provide additional menu items that should be displayed in the file or folder context menus for certain types of files.

Extensions that implement this interface should do its best to respond as fast as possible to method invokations by the file manager. That said, when the file manager calls the `thunarx_menu_provider_get_file_menu_items()` or the `thunarx_menu_provider_get_folder_menu_items()` method, the implementation in the extension should use only the `thunarx_file_info_has_mime_type()` and `thunarx_file_info_is_directory()` methods to determine the menu items that should be added to the file manager's context menu. Don't perform any complicated I/O to determine the menu items list, as that would block the whole file manager process.

The name of ThunarxMenuItems returned from the `thunarx_menu_provider_get_file_menu_items()` and `thunarx_menu_provider_get_folder_menu_items()` methods must be namespaced with the module to avoid collision with internal file manager menu items and menu items provided by other extensions. For example, the menu item provided by the `ThunarOpenTerminal` extension should be called `ThunarOpenTerminal::open-terminal`.

## Functions

### thunarx_menu_provider_get_file_menu_items ()

    GList *
    thunarx_menu_provider_get_file_menu_items
                                   (ThunarxMenuProvider *provider,
                                    GtkWidget *window,
                                    GList *files);

Returns the list of ThunarxMenuItems that `provider` has to offer for `files` .

As a special note, this method automatically takes a reference on the `provider` for every ThunarxMenuItem object returned from the real implementation of this method in `provider` . This is to make sure that the extension stays in memory for at least the time that the menu items are used. If the extension wants to stay in memory for a longer time, it'll need to take care of this itself (e.g. by taking an additional reference on the `provider` itself, that's released at a later time).

The caller is responsible to free the returned list of menu items using something like this when no longer needed:

    1
    g_list_free_full (list, g_object_unref);

[skip]

#### Parameters

provider | a ThunarxMenuProvider. |
window | the GtkWindow within which the menu items will be used. |
files | the list of ThunarxFileInfos to which the menu items will be applied. | [element-type ThunarxFileInfo]

#### Returns

the list of ThunarxMenuItems that `provider` has to offer for `files` .

### thunarx_menu_provider_get_folder_menu_items ()

    GList *
    thunarx_menu_provider_get_folder_menu_items
                                   (ThunarxMenuProvider *provider,
                                    GtkWidget *window,
                                    ThunarxFileInfo *folder);

Returns the list of ThunarxMenuItems that `provider` has to offer for `folder` .

As a special note, this method automatically takes a reference on the `provider` for every ThunarxMenuItem object returned from the real implementation of this method in `provider` . This is to make sure that the extension stays in memory for at least the time that the menu items are used. If the extension wants to stay in memory for a longer time, it'll need to take care of this itself (e.g. by taking an additional reference on the `provider` itself, that's released at a later time).

    g_list_free_full (list, g_object_unref);

#### Parameters

provider | a ThunarxMenuProvider. |
window | the GtkWindow within which the menu items will be used. |
folder | the folder to which the menu items should will be applied. |

#### Returns

the list of ThunarxMenuItems that `provider` has to offer for `folder` .

### thunarx_menu_provider_get_dnd_menu_items ()

    GList *
    thunarx_menu_provider_get_dnd_menu_items
                                   (ThunarxMenuProvider *provider,
                                    GtkWidget *window,
                                    ThunarxFileInfo *folder,
                                    GList *files);

Returns the list of ThunarxMenuItems that `provider` has to offer for dropping the `files` into the `folder` . For example, the thunar-archive-plugin provides Extract Here menu items when dropping archive files into a folder that is writable by the user.

As a special note, this method automatically takes a reference on the `provider` for every ThunarxMenuItem object returned from the real implementation of this method in `provider` . This is to make sure that the extension stays in memory for at least the time that the menu items are used. If the extension wants to stay in memory for a longer time, it'll need to take care of this itself (e.g. by taking an additional reference on the `provider` itself, that's released at a later time).

The caller is responsible to free the returned list of menu items using something like this when no longer needed:

    1
    g_list_free_full (list, g_object_unref);

[skip]

#### Parameters

provider | a ThunarxMenuProvider. |
window | the GtkWindow within which the menu items will be used. |
folder | the folder into which the `files` are being dropped |
files | the list of ThunarxFileInfos for the files that are being dropped to `folder` in `window` . | [element-type ThunarxFileInfo]

#### Returns

the list of ThunarxMenuItems that `provider` has to offer for dropping `files` to `folder` .
