There are a few + * reasons for this: + * + * 1) Richlists on OSX don't have focusrings; instead, they are shown as + * selected. This makes for some ambiguity when we have a focused/selected + * item in the list, and the mouse is hovering a completed download (which + * highlights). + * 2) Windows doesn't show focusrings until after the first time that tab is + * pressed (and by then you're focusing the second item in the panel). + * 3) Richlistbox sets -moz-focusring even when we select it with a mouse. + * + * In general, the desired behaviour is to focus the first item after pressing + * tab/down, and show that focus with a ring. Then, if the mouse moves over + * the panel, to hide that focus ring; essentially resetting us to the state + * before pressing the key. + * + * We end up capturing the tab/down key events, and preventing their default + * behaviour. We then set a "keyfocus" attribute on the panel, which allows + * us to draw a ring around the currently focused element. If the panel is + * closed or the mouse moves over the panel, we remove the attribute. + */ + +"use strict"; + +//////////////////////////////////////////////////////////////////////////////// +//// Globals + +XPCOMUtils.defineLazyModuleGetter(this, "DownloadUtils", + "resource://gre/modules/DownloadUtils.jsm"); +XPCOMUtils.defineLazyModuleGetter(this, "DownloadsCommon", + "resource:///modules/DownloadsCommon.jsm"); +XPCOMUtils.defineLazyModuleGetter(this, "OS", + "resource://gre/modules/osfile.jsm"); +XPCOMUtils.defineLazyModuleGetter(this, "PrivateBrowsingUtils", + "resource://gre/modules/PrivateBrowsingUtils.jsm"); +XPCOMUtils.defineLazyModuleGetter(this, "PlacesUtils", + "resource://gre/modules/PlacesUtils.jsm"); +XPCOMUtils.defineLazyModuleGetter(this, "NetUtil", + "resource://gre/modules/NetUtil.jsm"); + +//////////////////////////////////////////////////////////////////////////////// +//// DownloadsPanel + +/** + * Main entry point for the downloads panel interface. + */ +const DownloadsPanel = { + ////////////////////////////////////////////////////////////////////////////// + //// Initialization and termination + + /** + * Internal state of the downloads panel, based on one of the kState + * constants.
