* This render array will be a jQuery tab in the media browser.

|
* Some elements are special:
|
|
58
|
* - #settings: Drupal.settings.media.browser.$key (where key is the array
|
|
59
|
* key).
|
|
60
|
* - #callback: If provided, will make the tab an "ajax" tab.
|
|
61
|
* - #title: If provided, will be used as the tab's title. Otherwise the
|
|
62
|
* 'title' value from the plugin's hook_media_browser_plugin_info() will
|
|
63
|
* be used.
|
|
64
|
* - #weight: If provided, will be used to order the tabs between each other.
|
|
65
|
* A lower weight will be displayed first while a higher weight will be
|
|
66
|
* displayed later. If not provided, and there is a 'weight' value in the
|
|
67
|
* plugin's hook_media_browser_plugin_info() then it will be used,
|
|
68
|
* otherwise a default of 0 will be used.
|
|
69
|
* - form: If the plugin is to display a native Drupal form, then the output
|
|
70
|
* of drupal_get_form should be returned into the 'form' render key. If a
|
|
71
|
* form's callback isn't normally loaded, module_load_include() should be
|
|
72
|
* used to ensure that the form can be displayed.
|
|
73
|
*
|
|
74
|
* Example usage:
|
|
75
|
* @code
|
|
76
|
* module_load_include('inc', 'mymodule', 'mymodule.pages');
|
|
77
|
* $build['#attached']['js'][] = drupal_get_path('module', 'mymodule') . '/js/mymodule.media.browser.js';
|
|
78
|
* $build['form'] = drupal_get_form('mymodule_media_form');
|
|
79
|
* return $build;

|
