5          * mw.Upload.BookletLayout encapsulates the process of uploading a file
6          * to MediaWiki using the {@link mw.Upload upload model}.
7          * The booklet emits events that can be used to get the stashed
8          * upload and the final file. It can be extended to accept
9          * additional fields from the user for specific scenarios like
10          * for Commons, or campaigns.
11          *
12          * ## Structure
13          *
14          * The {@link OO.ui.BookletLayout booklet layout} has three steps:
15          *
16          *  - **Upload**: Has a {@link OO.ui.SelectFileWidget field} to get the file object.
17          *
18          * - **Information**: Has a {@link OO.ui.FormLayout form} to collect metadata. This can be
19          *   extended.
20          *
21          * - **Insert**: Has details on how to use the file that was uploaded.
22          *
23          * Each step has a form associated with it defined in
24          * {@link #renderUploadForm renderUploadForm},
25          * {@link #renderInfoForm renderInfoForm}, and
26          * {@link #renderInsertForm renderInfoForm}. The
27          * {@link #getFile getFile},
28          * {@link #getFilename getFilename}, and
29          * {@link #getText getText} methods are used to get
30          * the information filled in these forms, required to call
31          * {@link mw.Upload mw.Upload}.
32          *
33          * ## Usage
34          *
35          * See the {@link mw.Upload.Dialog upload dialog}.
36          *
37          * The {@link #event-fileUploaded fileUploaded},
38          * and {@link #event-fileSaved fileSaved} events can
39          * be used to get details of the upload.
40          *
41          * ## Extending
42          *
43          * To extend using {@link mw.Upload mw.Upload}, override
44          * {@link #renderInfoForm renderInfoForm} to render
45          * the form required for the specific use-case. Update the
46          * {@link #getFilename getFilename}, and
47          * {@link #getText getText} methods to return data
48          * from your newly created form. If you added new fields you'll also have
49          * to update the {@link #clear} method.
50          *
51          * If you plan to use a different upload model, apart from what is mentioned
52          * above, you'll also have to override the
53          * {@link #createUpload createUpload} method to
54          * return the new model. The {@link #saveFile saveFile}, and
55          * the {@link #uploadFile uploadFile} methods need to be
56          * overridden to use the new model and data returned from the forms.
57          *
58          * @class
59          * @extends OO.ui.BookletLayout
60          *
61          * @constructor
62          * @param {Object} config Configuration options
63          * @cfg {jQuery} [$overlay] Overlay to use for widgets in the booklet
64          * @cfg {string} [filekey] Sets the stashed file to finish uploading. Overrides most of the file selection process, and fetches a thumbnail from the server.
