4 * mw.Upload.BookletLayout encapsulates the process of uploading a file
5 * to MediaWiki using the {@link mw.Upload upload model}.
6 * The booklet emits events that can be used to get the stashed
7 * upload and the final file. It can be extended to accept
8 * additional fields from the user for specific scenarios like
9 * for Commons, or campaigns.
13 * The {@link OO.ui.BookletLayout booklet layout} has three steps:
15 * - **Upload**: Has a {@link OO.ui.SelectFileWidget field} to get the file object.
17 * - **Information**: Has a {@link OO.ui.FormLayout form} to collect metadata. This can be
20 * - **Insert**: Has details on how to use the file that was uploaded.
22 * Each step has a form associated with it defined in
23 * {@link #renderUploadForm renderUploadForm},
24 * {@link #renderInfoForm renderInfoForm}, and
25 * {@link #renderInsertForm renderInfoForm}. The
26 * {@link #getFile getFile},
27 * {@link #getFilename getFilename}, and
28 * {@link #getText getText} methods are used to get
29 * the information filled in these forms, required to call
30 * {@link mw.Upload mw.Upload}.
34 * See the {@link mw.Upload.Dialog upload dialog}.
36 * The {@link #event-fileUploaded fileUploaded},
37 * and {@link #event-fileSaved fileSaved} events can
38 * be used to get details of the upload.
42 * To extend using {@link mw.Upload mw.Upload}, override
43 * {@link #renderInfoForm renderInfoForm} to render
44 * the form required for the specific use-case. Update the
45 * {@link #getFilename getFilename}, and
46 * {@link #getText getText} methods to return data
47 * from your newly created form. If you added new fields you'll also have
48 * to update the {@link #clear} method.
50 * If you plan to use a different upload model, apart from what is mentioned
51 * above, you'll also have to override the
52 * {@link #createUpload createUpload} method to
53 * return the new model. The {@link #saveFile saveFile}, and
54 * the {@link #uploadFile uploadFile} methods need to be
55 * overridden to use the new model and data returned from the forms.
