/**
* This function creates an upload widget — a placeholder to show the progress of an upload. The upload widget
* is based on its {@link CKEDITOR.fileTools.uploadWidgetDefinition definition}. The `addUploadWidget` method also
* creates a `paste` event, if the {@link CKEDITOR.fileTools.uploadWidgetDefinition#fileToElement fileToElement} method
* is defined. This event helps in handling pasted files, as it will automatically check if the files were pasted and
* mark them to be uploaded.
*
* The upload widget helps to handle content that is uploaded asynchronously inside the editor. It solves issues such as:
* editing during upload, undo manager integration, getting data, removing or copying uploaded element.
*
* To create an upload widget you need to define two transformation methods:
*
* * The {@link CKEDITOR.fileTools.uploadWidgetDefinition#fileToElement fileToElement} method which will be called on
* `paste` and transform a file into a placeholder.
* * The {@link CKEDITOR.fileTools.uploadWidgetDefinition#onUploaded onUploaded} method with
* the {@link CKEDITOR.fileTools.uploadWidgetDefinition#replaceWith replaceWith} method which will be called to replace
* the upload placeholder with the final HTML when the upload is done.
* If you want to show more information about the progress you can also define
* the {@link CKEDITOR.fileTools.uploadWidgetDefinition#onLoading onLoading} and
* {@link CKEDITOR.fileTools.uploadWidgetDefinition#onUploading onUploading} methods.
*
* The simplest uploading widget which uploads a file and creates a link to it may look like this:
*
* CKEDITOR.fileTools.addUploadWidget( editor, 'uploadfile', {
* uploadUrl: CKEDITOR.fileTools.getUploadUrl( editor.config ),
*
* fileToElement: function( file ) {
* var a = new CKEDITOR.dom.element( 'a' );
* a.setText( file.name );
* a.setAttribute( 'href', '#' );
* return a;
* },
*
* onUploaded: function( upload ) {
* this.replaceWith( '<a href="' + upload.url + '" target="_blank">' + upload.fileName + '</a>' );
* }
* } );
*
* The upload widget uses {@link CKEDITOR.fileTools.fileLoader} as a helper to upload the file. A
* {@link CKEDITOR.fileTools.fileLoader} instance is created when the file is pasted and a proper method is
* called &mdash; by default it is the {@link CKEDITOR.fileTools.fileLoader#loadAndUpload} method. If you want
* to only use the `load` or `upload`, you can use the {@link CKEDITOR.fileTools.uploadWidgetDefinition#loadMethod loadMethod}
* property.
*
* Note that if you want to handle a big file, e.g. a video, you may need to use `upload` instead of
* `loadAndUpload` because the file may be too big to load it to memory at once.
*
* If you do not upload the file, you need to define {@link CKEDITOR.fileTools.uploadWidgetDefinition#onLoaded onLoaded}
* instead of {@link CKEDITOR.fileTools.uploadWidgetDefinition#onUploaded onUploaded}.
* For example, if you want to read the content of the file:
*
* CKEDITOR.fileTools.addUploadWidget( editor, 'fileReader', {
* loadMethod: 'load',
* supportedTypes: /text\/(plain|html)/,
*
* fileToElement: function( file ) {
* var el = new CKEDITOR.dom.element( 'span' );
* el.setText( '...' );
* return el;
* },
*
* onLoaded: function( loader ) {
* this.replaceWith( atob( loader.data.split( ',' )[ 1 ] ) );
* }
* } );
*
* If you need to pass additional data to the request, you can do this using the
* {@link CKEDITOR.fileTools.uploadWidgetDefinition#additionalRequestParameters additionalRequestParameters} property.
* That data is then passed to the upload method defined by {@link CKEDITOR.fileTools.uploadWidgetDefinition#loadMethod},
* and to the {@link CKEDITOR.editor#fileUploadRequest} event (as part of the `requestData` property).
* The syntax of that parameter is compatible with the {@link CKEDITOR.editor#fileUploadRequest} `requestData` property.
*
* CKEDITOR.fileTools.addUploadWidget( editor, 'uploadFile', {
* additionalRequestParameters: {
* foo: 'bar'
* },
*
* fileToElement: function( file ) {
* var el = new CKEDITOR.dom.element( 'span' );
* el.setText( '...' );
* return el;
* },
*
* onUploaded: function( upload ) {
* this.replaceWith( '<a href="' + upload.url + '" target="_blank">' + upload.fileName + '</a>' );
* }
* } );
*
* If you need custom `paste` handling, you need to mark the pasted element to be changed into an upload widget
* using {@link CKEDITOR.fileTools#markElement markElement}. For example, instead of the `fileToElement` helper from the
* example above, a `paste` listener can be created manually:
*
* editor.on( 'paste', function( evt ) {
* var file, i, el, loader;
*
* for ( i = 0; i < evt.data.dataTransfer.getFilesCount(); i++ ) {
* file = evt.data.dataTransfer.getFile( i );
*
* if ( CKEDITOR.fileTools.isTypeSupported( file, /text\/(plain|html)/ ) ) {
* el = new CKEDITOR.dom.element( 'span' ),
* loader = editor.uploadRepository.create( file );
*
* el.setText( '...' );
*
* loader.load();
*
* CKEDITOR.fileTools.markElement( el, 'filereader', loader.id );
*
* evt.data.dataValue += el.getOuterHtml();
* }
* }
* } );
*
* Note that you can bind notifications to the upload widget on paste using
* the {@link CKEDITOR.fileTools#bindNotifications} method, so notifications will automatically
* show the progress of the upload. Because this method shows notifications about upload, do not use it if you only
* {@link CKEDITOR.fileTools.fileLoader#load load} (and not upload) a file.
*
* editor.on( 'paste', function( evt ) {
* var file, i, el, loader;
*
* for ( i = 0; i < evt.data.dataTransfer.getFilesCount(); i++ ) {
* file = evt.data.dataTransfer.getFile( i );
*
* if ( CKEDITOR.fileTools.isTypeSupported( file, /text\/pdf/ ) ) {
* el = new CKEDITOR.dom.element( 'span' ),
* loader = editor.uploadRepository.create( file );
*
* el.setText( '...' );
*
* loader.upload();
*
* CKEDITOR.fileTools.markElement( el, 'pdfuploader', loader.id );
*
* CKEDITOR.fileTools.bindNotifications( editor, loader );
*
* evt.data.dataValue += el.getOuterHtml();
* }
* }
