In 4.0 you have views which are defined by module definitions. The definition is created by definition elements which are similar to controls. Inside the definition you need to have methods which use DialogElement class and DefinitionsHelper.CreateDialogElement method. You can take a look at this post
Basically you can add the permissions by creating an instance of CommandWidgetElement
CommandWidgetElement modulePermissions = new CommandWidgetElement(settings.Items)
Name = "ModulePermissions",
CommandName = DefinitionsHelper.PermissionsCommandName,
ButtonType = CommandButtonType.SimpleLinkButton,
Text = "PermissionsForMyModule",
ResourceClassId = typeof(ModuleResources).Name,
WidgetType = typeof(CommandWidget),
IsSeparator = false
We will have a sample module -Products for the official release where you will be able to see how to create custom module, definition class, dialogs, custom controls etc.
