Starting in + * Windows Vista, the taskbar began showing live thumbnail previews of windows + * when the user hovered over the window icon in the taskbar. Starting with + * Windows 7, the taskbar allows an application to expose its tabbed interface + * in the taskbar by showing thumbnail previews rather than the default window + * preview. Additionally, when a user hovers over a thumbnail (tab or window), + * they are shown a live preview of the window (or tab + its containing window). + * + * In Windows 7, a title, icon, close button and optional toolbar are shown for + * each preview. This feature does not make use of the toolbar. For window + * previews, the title is the window title and the icon the window icon. For + * tab previews, the title is the page title and the page's favicon. In both + * cases, the close button "does the right thing." + * + * The primary objects behind this feature are nsITaskbarTabPreview and + * nsITaskbarPreviewController. Each preview has a controller. The controller + * responds to the user's interactions on the taskbar and provides the required + * data to the preview for determining the size of the tab and thumbnail. The + * PreviewController class implements this interface. The preview will request + * the controller to provide a thumbnail or preview when the user interacts with + * the taskbar. To reduce the overhead of drawing the tab area, the controller + * implementation caches the tab's contents in a <canvas> element. If no + * previews or thumbnails have been requested for some time, the controller will + * discard its cached tab contents. + * + * Screen real estate is limited so when there are too many thumbnails to fit + * on the screen, the taskbar stops displaying thumbnails and instead displays + * just the title, icon and close button in a similar fashion to previous + * versions of the taskbar. If there are still too many previews to fit on the + * screen, the taskbar resorts to a scroll up and scroll down button pair to let + * the user scroll through the list of tabs. Since this is undoubtedly + * inconvenient for users with many tabs, the AeroPeek objects turns off all of + * the tab previews. This tells the taskbar to revert to one preview per window. + * If the number of tabs falls below this magic threshold, the preview-per-tab + * behavior returns. There is no reliable way to determine when the scroll + * buttons appear on the taskbar, so a magic pref-controlled number determines + * when this threshold has been crossed. + */ +this.EXPORTED_SYMBOLS = ["AeroPeek"]; + +const Cc = Components.classes; +const Ci = Components.interfaces; +const Cu = Components.utils; + +Cu.import("resource://gre/modules/NetUtil.jsm"); +Cu.import("resource://gre/modules/PlacesUtils.jsm"); +Cu.import("resource://gre/modules/PrivateBrowsingUtils.jsm"); +Cu.import("resource://gre/modules/Services.jsm"); +Cu.import("resource://gre/modules/XPCOMUtils.jsm"); + +// Pref to enable/disable preview-per-tab +const TOGGLE_PREF_NAME = "browser.taskbar.previews.enable"; +// Pref to determine the magic auto-disable threshold +const DISABLE_THRESHOLD_PREF_NAME = "browser.taskbar.previews.max"; +// Pref to control the time in seconds that tab contents live in the cache +const CACHE_EXPIRATION_TIME_PREF_NAME = "browser.taskbar.previews.cachetime"; + +const WINTASKBAR_CONTRACTID = "@mozilla.org/windows-taskbar;1"; + +// Various utility properties +XPCOMUtils.defineLazyServiceGetter(this, "imgTools", + "@mozilla.org/image/tools;1", + "imgITools"); +XPCOMUtils.defineLazyModuleGetter(this, "PageThumbs", + "resource://gre/modules/PageThumbs.jsm"); + +// nsIURI -> imgIContainer +function _imageFromURI(uri, privateMode, callback) { + let channel = NetUtil.newChannel({ + uri: uri, + loadUsingSystemPrincipal: true, + contentPolicyType: Ci.nsIContentPolicy.TYPE_INTERNAL_IMAGE + }); + + try { + channel.QueryInterface(Ci.nsIPrivateBrowsingChannel); + channel.setPrivate(privateMode); + } catch (e) { + // Ignore channels which do not support nsIPrivateBrowsingChannel + } + NetUtil.asyncFetch(channel, function(inputStream, resultCode) { + if (!Components.isSuccessCode(resultCode)) + return; + try { + let out_img = { value: null }; + imgTools.decodeImageData(inputStream, channel.contentType, out_img); + callback(out_img.value); + } catch (e) { + // We failed, so use the default favicon (only if this wasn't the default + // favicon). + let defaultURI = PlacesUtils.favicons.defaultFavicon; + if (!defaultURI.equals(uri)) + _imageFromURI(defaultURI, privateMode, callback); + } + }); +} + +// string? -> imgIContainer +function getFaviconAsImage(iconurl, privateMode, callback) { + if (iconurl) { + _imageFromURI(NetUtil.newURI(iconurl), privateMode, callback); + } else { + _imageFromURI(PlacesUtils.favicons.defaultFavicon, privateMode, callback); + } +} + +// Snaps the given rectangle to be pixel-aligned at the given scale +function snapRectAtScale(r, scale) { + let x = Math.floor(r.x * scale); + let y = Math.floor(r.y * scale); + let width = Math.ceil((r.x + r.width) * scale) - x; + let height = Math.ceil((r.y + r.height) * scale) - y; + + r.x = x / scale; + r.y = y / scale; + r.width = width / scale; + r.height = height / scale; +} + +// PreviewController + +/* + * This class manages the behavior of thumbnails and previews.
