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.
