It represents a design and architectural change with regard to user experience! and offers significant improvements in user productivity. Figure 1 shows the Windows 1.0 taskbar. Analysis from a number of user sessions during recent years has shown that having an abundance of launch surfaces does not necessarily make the users work any easier. As far as user interface design is concerned! to prevent user confusion its often better to have only one way to accomplish a task. The design goals of the Windows 7 taskbar are to bring control back to the user and to minimize confusion! by supporting the following principles: Single launch surface for frequent programs and destinations. This helps keep those applications and data that you use all the time right at your fingertips. Easy to control! where switching between applications and windows and arranging windows are made easy and manageable. Clean! noise-free! simple. Large taskbar buttons! visual clarity! and sleekness of design dominate users experience once they are logged on to Windows 7. But how can developers leverage the new functionality that the Windows 7 taskbar has to offer How do the underlying mechanisms work together to enable the best user experience In this article! we will explore the new features and underlying functionality of the Windows 7 taskbar! supported with examples in native and managed code. Taskbar buttons provide the gateway to access the functionality of the new Windows 7 taskbar. The biggest thing to notice is that the taskbar also contains icons for applications that are not currently running. For example! the user may pin applications to the taskbar! which results in a pinned icon on the taskbar but the application is not running. Clicking the icon causes the app to launch. This is a unification of the Quick Launch concept and the standard Windows taskbar. In fact! there is no need for the Quick Launch area on Windows 7 any longer。 the only reason the Quick Launch folder is still in Windows 7 is for backwards compatibility. You may have already heard about jump lists! thumbnail toolbars! taskbar progress bars! and other features. They are all connected with the large! redesigned taskbar buttons that occupy the new taskbar. The Windows 7 taskbar buttons! shown in Figure 2! are identified with multiple visual effects. They make it possible to immediately identify which applications are running! whether there are multiple windows in the same application! which application is currently active! and which taskbar button currently has the mouse hovering over it. All the Windows 7 taskbar features are unlocked only after you have created the taskbar button for your application. This makes sense! since you cant change the taskbar overlay icon! for example! if there is no taskbar button yet In practice! this means that managed and native applications using the new Windows 7 taskbar APIs will have to wait for a new window message! identifiable by the TaskbarButtonCreated string. To obtain the identifier of this message! you must call the RegisterWindowMessage Win32 API and pass the TaskbarButtonCreated string as a parameter. The following code shows how a Win32 application receives the window message indicating that the taskbar button is created: Now you know how to make sure that your application does not use the Windows 7 taskbar before there is a taskbar button in place. Before we jump to more interesting features! theres just one additional piece of information that you need to complete the puzzle. How are taskbar buttons associated with windows and applications How does the system decide whether an application needs two taskbar buttons for its different windows or whether multiple applications need to share a single taskbar button The answer is application ID. This is a new property of the Windows Shell and is an attribute of windows! processes and shell links . By controlling the application ID of individual windows and processes! application developers can ensure that the taskbar buttons are associated to their windows exactly as they deem fit. The application ID is a stringnot a GUIDthat can take a free format of up to 128 characters. To make sure application IDs do not accidentally collide! the recommendation is to include in the application ID the company name! product name! and application name. The default application ID for a window is determined by the default application ID for the process to which the window belongs. This is! in turn! a default application ID generated for the executable file that the process runs. Try launching an application like Notepad several times to see this in action. There is only one taskbar button created even if you run multiple instances of Notepad at the same time.没有其他倡议此为机械翻译形式!社区成员可对其停止编纂我们拾分期看您能单击与以下任壹句子关联的编纂链接!
