  • [TDM, DEV][Windows 7 Taskbar Details]In the earlier taskbar posts, we discussed how Windows Media Player’s deskband offers valuable background music controls, but only a mere 3% of sessions ever enjoy the functionality. The new taskbar exposes a feature called Thumbnail Toolbars that surface up to seven window controls right in context of taskbar buttons. Unlike a Jump List that applies globally to a program, this toolbar is contextual to just a specific window. By embracing this new feature, Media Player can now reach a majority of peopleDoes your window require controls?Surface commands that users access regularlyCommands must be contextual to a windowDon’t duplicate Jump List tasksCan you replace a Desktop Toolbar?
  • Native codeUINT wm_tbc = RegisterWindowMessage( "TaskbarButtonCreated");MSG m; GetMessage(..., &m);if (m.message == wm_tbc) { ITaskbarList3* ptl = ...; THUMBBUTTON btn = {...};ptl->ThumbBarAddButtons(m.hWnd, 1, &btn);}
  • [TDM, DEV]All the major web browsers offer tabs and a method of managing these tabs. One could argue tab toolbars are really like taskbars since they facilitate switching. These TDI (Tabbed Document Interface) and MDI (Multiple Document Interface) programs have always resorted to creating their own internal window management systems as the Windows taskbar was not optimized to help their scenarios. Some programs like Excel did custom work to surface their child windows on the taskbar, but this approach was somewhat of a hack.Since the new taskbar already groups individual windows of a program under a single button, we can now offer a standard way for programs that have child windows to expose them. Again, the taskbar offers a single, consistent place to access real windows as well as child windows. These custom window switchers also behave as regular windows on the taskbar with rich thumbnails and even Aero Peek.Does your program have switchers that need to be surfaced?Do users need to regularly switch to them?Provide a visual representation for your client area’s switcherTaskbar bitmap (thumbnail)Peek bitmap (real size)
  • Native Use ITaskbarList3::RegisterTab, SetTabOrder, SetTabActiveChild window must create a proxy top-level window for custom thumbnail and peekThe proxy window is typically invisibleProxy window must handle WM_ACTIVATE and WM_SYSCOMMAND
  • [TDM, DEV][Windows 7 Taskbar Details – Important enough to not hide]Jump Lists are a new feature of the Windows 7 taskbar that accomplish just this. Think of this feature as a mini Start Menu for each program or an evolved version of the system menu. First, the you don’t need to even start the program to quickly launch a file or access a task. Second, destinations don’t take up valuable space on the taskbar; they are automatically organized by their respective program in a simple list. Should one have ten programs pinned or running on her taskbar, this means she could have quick access to over 150 destinations she uses all the time, without even the need to customize the UI! Since the Jump List shows lots of text for each of its items, gone are the days of having identical icons on your taskbar that are indistinguishable without a tooltip. Should you wish to keep a specific destination around, you can simply pin it to the list.
  • [ DEV][Why - Windows 7 Taskbar details]Jump Lists are a new feature of the Windows 7 taskbar that accomplish just this. Think of this feature as a mini Start Menu for each program or an evolved version of the system menu. Jump Lists surface commonly used nouns (destinations) and verbs (tasks) of a program. There are several advantages this new approach provides. Do destinations apply to your program?Nouns: Items consumed/created by your programDynamic based upon individual user patternRecent or frequent or custom list?Do tasks apply to your program?Verbs: Program actionsTasks should not require your program to be runningTasks are static and apply to all usersTasks should globally apply to your program, not a specific window

  • 1 demo on Scenic ribbon
  • [TDM, DEV][What- Windows 7 Ribbon Platform overview]The Ribbon – a very successful concept from Office 2007 has become a first class citizen in Windows 7 and it is evolved into a developer platform. Many developers asked us to enable ease access to the office Ribbon. So in Windows 7 we have created the Ribbon which will also be redistributed available to Windows VistaIt is a Win 32 native COM base APIAnd it has a very close functionality to the office Ribbon
  • [TDM, DEV][What - Windows 7 Ribbon Platform available controls]Show Live Movie Maker Beta to emphasize that other Windows apps are using the Ribbon
  • [TDM, DEV]Sensor Platform Windows 7 has changed how developers use sensors. It includes native support for sensors, expanded by a new development platform for working with sensors, including location sensors, such as GPS devices. Built on the Sensor platform, the Windows Location APIs are a new Windows 7 feature that enables application developers to access the user’s physical location information. The Windows Location APIs can abstract hardware, simultaneously support multiple applications, and seamlessly switch between different technologies, relieving the application developer of the burden of managing these constraints. The Location APIs can be used by programmers through the C++ programming language (by programmers familiar with COM), or by using COM objects in scripting languages, such as JScript®. Scripting support gives easy access to location data for projects such as gadgets or web pages.Windows 7 provides a solid, easy-to-use platform for using sensor devices, such as an ambient light sensor or a temperature gauge, to create environmental awareness in Windows applications. PCs can use sensors that are built into the computer, connected through wired or wireless connections, or connected through a network or the Internet.The Sensor and Location APIs provide a standard way to discover sensors, and to programmatically access data that sensors provideThe Sensor control panel lets users enable or disable sensors, control access to sensors that might expose sensitive data, view sensor properties, and change the descriptions of sensors.The Sensor Class Extension is a core part of the driver development model for the Sensor platform. It provides the following mechanisms, which are used when writing a User-Mode Driver Framework (UMDF) sensor driver:Integration with the Sensor platformSecurity enforcement

    Icon Overlay
    Surface important notifications
    Appears over your program’s icon
    Progress bar
    Surface important notifications
    Appears in your taskbar button
  • IconsBest practices
    Are you putting your best foot forward?
    Make sure your icon looks great
    Check different DPIs
    Check different glass colors and disabled glass
    How does Color Hot-track look?
    Determined by your icon’s dominant color
  • Get More From Taskbar ButtonsOverlay and progress icons
    Consolidate: Uncluttered notification area
    Provide progress and additional information through the taskbar button
    It’s free if you use standard progress dialogs
  • Taskbar Overlay and ProgressDesign considerations
    Notification area is now user controlled:
    Leave yourself out if possible!
    Use taskbar buttons for custom progress or status information
  • Peek Preview (Aero Peek)
    Live peek without a click
  • Live Thumbnails
    Live thumbnails: A live preview
    Windows Vista: One thumbnail per window
    Windows 7: Grouped thumbnails
  • Windows 7 Taskbar – Thumbnails
    Remote-control for a window
    Surface key commands
    Accessible from taskbar thumbnail
    Up to seven buttons
  • Thumbnail ToolbarsContrasting Thumbnail Toolbar commands and user tasks
  • Exposing Custom ThumbnailsOverriding Automatic Thumbnail Preview
    To provide a custom thumbnail preview representation for a window:
    Set the DWM window attribute to say you will provide an “iconic bitmap” for the window
    Respond to the window messages DWM will then send in order to set the preview – done for both thumbnail- and full-sized previews
  • Hi phone!
  • Windows 7 Taskbar – Custom Switchers
    Surface custom UI (e.g. TDI/MDI)
    Custom thumbnails for each window

  • Pinned category
    Known categories
    Custom categories
    User Tasks
    Taskbar Tasks
    Windows 7 Taskbar – Jump Lists
  • Customizing the Jump ListStep 1: Get the free stuff to work
    Associate your program with the file extension
    Use common file dialogs
    Use explicit recent document API
  • Customizing the Jump ListStep 2: Adding tasks
    What would your user like to do?
    Launch your application with special arguments?
    Launch other applications?
    Tasks are IShellLink objects
    Rich shortcut semantics including arguments, working directory, icon, and so on.
  • Customizing the Jump ListStep 3: Do you have categories?
    Does it make sense to categorize documents?
    Is frequent, recent, pinned not enough?
    For example, Inbox, Outbox, Sales, Marketing …
    Categories contain IShellItem or IShellLink objects
    These are documents: You need a file association

  • Sensor & Location API
  • Limitations Of Sensors Today
    Location devices exposed as virtual COM ports
    Exclusive application access
    Not secure
    Proprietary data formats (NMEA, others)
    GPS doesn’t work indoors
    Hard to support multiple technologies at once
    Sensors are integrated as vertical solutions
    Applications need to know sensorhardware specifics
    Limited adoption and scope
  • Sensor And Location Platform
    Provides unified driver model for all types of sensor devices
    Physical sensors (e.g., GPS devices, Light Sensors)
    Logical sensor (e.g., Wi-Fi triangulation resolver)
    Provides standard APIs for accessing sensors
    Sensor API: C++/COM / Managed code (Windows Bridge)
    Raw access to any sensor
    Location API: C++/COM, Idispatch
    Managed code (Windows 7 API Code Pack)
    Abstracted API for location data
    Puts user in control of information disclosure
  • Sensor Architecture
    Sensor API
    Location and Other Sensors Control Panel

  • What Info Do Sensors Use?
    Enumerated via category and type
    Category represents what is being sensed
    Type represents how it is sensed
    Properties (read-only or read-write)
    Data (property keys for units, data field…)
    Events (data-driven)
  • Location Platform Benefits
    Single API call to answer “Where am I?”
    Independent of provider used todetermine location
    Synchronous and Asynchronous models
    Script/automation compatible
    Automatic transition between providers
    Most accurate providers have priority
    Concurrent access for multiple applications
    Default Location
    Provided by user as fallback when no other sources are available

    Most common format
    Best format for precise location
    Can reverse geo-code later
    Civic Address (ICivicAddressReport)
    Zip, Country required
    Most human readable
    Best for ‘rough’ location estimates,street directions
    Types Of Location Data
  • Location data is considered PII (user consent required)
    All sensors are disabled by default
    Admin rights required to enable a sensor
    Sensors can be configured on a per-user basis
    “Enable Dialog” invoked by applications
    Privacy And Access Control
  • Location Summary
    • C++/COM
    • IDispatch (script, .NET interop)
    Single, convenient API for accessing current location
    • Lat/Long and Address formats
    Enables applications to be device-agnostic
    User consent required toaccess data
    • Opt-in via ‘Enable Dialog’ orControl Panel
  • Sensor Demo
  • Light-Aware Applications
    Photos taken in direct sunlight
    UI with light-awareness,
    100% screen brightness
    UI without light-awareness,
    40% screen brightness
