7 * @fileOverview The "filebrowser" plugin that adds support for file uploads and
8 * browsing.
9 *
10 * When a file is uploaded or selected inside the file browser, its URL is
11 * inserted automatically into a field defined in the <code>filebrowser</code>
12 * attribute. In order to specify a field that should be updated, pass the tab ID and
13 * the element ID, separated with a colon.<br /><br />
14 *
15 * <strong>Example 1: (Browse)</strong>
16 *
17 * <pre>
18 * {
19 * type : 'button',
20 * id : 'browse',
21 * filebrowser : 'tabId:elementId',
22 * label : editor.lang.common.browseServer
23 * }
24 * </pre>
25 *
26 * If you set the <code>filebrowser</code> attribute for an element other than
27 * the <code>fileButton</code>, the <code>Browse</code> action will be triggered.<br /><br />
28 *
29 * <strong>Example 2: (Quick Upload)</strong>
30 *
31 * <pre>
32 * {
33 * type : 'fileButton',
34 * id : 'uploadButton',
35 * filebrowser : 'tabId:elementId',
36 * label : editor.lang.common.uploadSubmit,
37 * 'for' : [ 'upload', 'upload' ]
38 * }
39 * </pre>
40 *
41 * If you set the <code>filebrowser</code> attribute for a <code>fileButton</code>
42 * element, the <code>QuickUpload</code> action will be executed.<br /><br />
43 *
44 * The filebrowser plugin also supports more advanced configuration performed through
45 * a JavaScript object.
46 *
47 * The following settings are supported:
48 *
49 * <ul>
50 * <li><code>action</code> &ndash; <code>Browse</code> or <code>QuickUpload</code>.</li>
51 * <li><code>target</code> &ndash; the field to update in the <code><em>tabId:elementId</em></code> format.</li>
52 * <li><code>params</code> &ndash; additional arguments to be passed to the server connector (optional).</li>
53 * <li><code>onSelect</code> &ndash; a function to execute when the file is selected/uploaded (optional).</li>
54 * <li><code>url</code> &ndash; the URL to be called (optional).</li>
55 * </ul>
56 *
57 * <strong>Example 3: (Quick Upload)</strong>
58 *
59 * <pre>
60 * {
61 * type : 'fileButton',
62 * label : editor.lang.common.uploadSubmit,
63 * id : 'buttonId',
64 * filebrowser :
65 * {
66 * action : 'QuickUpload', // required
67 * target : 'tab1:elementId', // required
68 * params : // optional
69 * {
70 * type : 'Files',
71 * currentFolder : '/folder/'
72 * },
73 * onSelect : function( fileUrl, errorMessage ) // optional
74 * {
75 * // Do not call the built-in selectFuntion.
76 * // return false;
77 * }
78 * },
79 * 'for' : [ 'tab1', 'myFile' ]
80 * }
81 * </pre>
82 *
83 * Suppose you have a file element with an ID of <code>myFile</code>, a text
84 * field with an ID of <code>elementId</code> and a <code>fileButton</code>.
85 * If the <code>filebowser.url</code> attribute is not specified explicitly,
86 * the form action will be set to <code>filebrowser[<em>DialogWindowName</em>]UploadUrl</code>
87 * or, if not specified, to <code>filebrowserUploadUrl</code>. Additional parameters
88 * from the <code>params</code> object will be added to the query string. It is
89 * possible to create your own <code>uploadHandler</code> and cancel the built-in
90 * <code>updateTargetElement</code> command.<br /><br />
91 *
92 * <strong>Example 4: (Browse)</strong>
93 *
94 * <pre>
95 * {
96 * type : 'button',
97 * id : 'buttonId',
98 * label : editor.lang.common.browseServer,
99 * filebrowser :
100 * {
101 * action : 'Browse',
102 * url : '/ckfinder/ckfinder.html&amp;type=Images',
103 * target : 'tab1:elementId'
104 * }
105 * }
106 * </pre>
107 *
108 * In this example, when the button is pressed, the file browser will be opened in a
109 * popup window. If you do not specify the <code>filebrowser.url</code> attribute,
110 * <code>filebrowser[<em>DialogName</em>]BrowseUrl</code> or
111 * <code>filebrowserBrowseUrl</code> will be used. After selecting a file in the file
112 * browser, an element with an ID of <code>elementId</code> will be updated. Just
113 * like in the third example, a custom <code>onSelect</code> function may be defined.
