`ABSTRACT
`
`In a graphical desktop environment displaying desktop
`components, a control is provided to track the position of a
`pointer on a screen, and when the pointer enters relevant
`regions with respect to a desktop component, a thin or thick
`border in displayed around the desktop componentto enable
`a user to resize the desktop component, and/or a caption bar
`is displayed along an edge of the componentto enable a user
`to move the desktop componenton the desktop. The caption
`bar may additionally be provided with menu and close
`buttons, to enable the user to bring up a menuof properties
`and/or actions for the desktop component, and close the
`desktop component, respectively. When the pointer is out-
`side any region relevant to a desktop component, no borders
`or caption bars are displayed, thereby resulting in a visually
`less cluttered appearance.

`MANAGING POSITION AND SIZE FORA
`DESKTOP COMPONENT
`
`FIELD OF THE INVENTION
`
`The present invention is directed to the field of graphical
`user interfaces, and more specifically to the manipulation of
`visual components in such interfaces.
`
`BACKGROUND OF THE INVENTION
`
`Manyof today’s computers are accessible through graphi-
`cal user interfaces (GUIs). One popular implementation is
`Windows 95, by Microsoft Corporation, of Redmond,
`Wash., which is a windows-based operating system,
`in
`which multiple applications may independently execute
`under the operating system, each within its own separate
`window.
`
`In a windows-based operating system, interaction with the
`computer is presented to the user through a desktop theme,
`under which commonly used applications and/or documents
`are displayed and accessed using graphical icons on the
`desktop.
`In recent years, there has been a tremendousproliferation
`of computers connected to a global network known as the
`Internet. A “client” computer connected to the Internet can
`downloaddigital information from “server” computers con-
`nected to the Internet. Client application software executing
`on client computers typically accept commands from a user
`and obtain data and services by sending requests to server
`applications running on server computers connected to the
`Internet. A numberof protocols are used to exchange com-
`mands and data between computers connected to the Inter-
`net. The protocols include the File Transfer Protocol (FTP),
`the Hypertext Transfer Protocol (HTTP), the Simple Mail
`Transfer Protocol (SMTP), and the “Gopher” document
`protocol.
`The HTTP protocol is used to access data on the World
`Wide Web, often referred to as “the Web.” The World Wide
`Web is an information service on the Internet providing
`documents and links between documents. The World Wide
`Web is made up of numerous Websites around the world
`that maintain and distribute electronic documents. A Web
`
`site may use one or more Web server computers that store
`and distribute documents in one of a number of formats
`including the Hypertext Markup Language (HTML). An
`HTMLdocument contains text and metadata or commands
`
`providing formatting information. HTML documents also
`include embedded“links” that reference other data or docu-
`ments located on any Web server computers. The referenced
`documents may represent text, graphics, or video in respec-
`tive formats.
`
`A Web browseris a client application or operating system
`utility that communicates with server computers via FTP,
`HTTP, and Gopher protocols. Web browsers receive elec-
`tronic documents from the network and present them to a
`user.
`Internet Explorer, available from Microsoft
`Corporation, of Redmond, Wash., is an example of a popular
`Web browser application.
`In addition to data and metadata, HTML documents can
`contain embedded software components containing program
`code that perform a wide variety of operations. These
`software components expand the interactive ability of an
`HTML document’s user interface. The components can
`perform other operations, such as manipulating data and
`playing audio or video clips. ActiveX is a specification
`
`2
`developed by Microsoft Corporation for creating software
`components that can be embedded into an HTML document.
`Java is a well-known programming language that can be
`used to develop components called “applets,” which are
`transmitted with HTML documents from Web servers to
`client computers. JavaScript and VBScript are scripting
`languages that are also used to extend the capabilities of
`HTML.JavaScript and VBScript scripts are embedded in
`HTML documents. A browser executes each script as it
`reachesthe position in the script during interpretation of the
`HTMLdocument.
`
`With today’s windows-based operating systems, which
`are multi-tasking, a user may use a web browser to open
`multiple windows, each with different content. Since each
`HTML document may contain scripts of various types,
`which may in turn open additional windows,a user’s desk-
`top display can quickly becomevisually cluttered due to
`each window having such elements as borders, control tabs,
`menubars,title bars, scroll bars, minimize, maximize, and
`restore buttons, resizing comers, and other elements which
`provide functionality to windows.
`SUMMARYOF THE INVENTION
`
`The present invention provides a control which tracks the
`position of a pointer on the display screen to monitor its
`location relative to one or more desktop components. These
`desktop components, some of which normally benefit from
`having associated borders, caption bars, and/or other win-
`dow functionality elements displayed therewith, are dis-
`played as images lacking these elements until relevant
`pointer events are detected by the control, whereupon the
`associated element
`is displayed,
`thereby reducing visual
`clutter. For instance, when the control detects that
`the
`pointer has completely entered a region defined by a desktop
`component, a thin, one-pixel border is displayed around the
`desktop component. When the pointer intersects with an
`edge of the desktop component, a thicker, three-pixel border
`is displayed. Whenthe pointer is close to the top edge of the
`desktop element, a caption baris displayed atop the desktop
`component. When the pointer moves away from the desktop
`component, the control disappears, rendering borders and
`caption bars invisible.

`general purpose personal computer. FIG. 1 and the following
`discussion are intended to provide a brief, general descrip-
`tion of a suitable computing environment
`in which the
`invention may be implemented. Although not required, the
`invention will be described in the general context of
`computer-executable instructions, such as program modules,
`being executed by a personal computer. Generally, program
`modules include routines, programs, objects, components,
`data structures, etc. that perform particular tasks or imple-
`mentparticular abstract data types. Moreover, those skilled
`in the art will appreciate that the invention maybe practiced
`with other computer system configurations, including hand-
`held devices, multiprocessor systems, microprocessor-based
`or programmable consumer electronics, network PCs,
`minicomputers, mainframe computers, and the like. The
`invention may also be practiced in distributed computing
`environments where tasks are performed by remote process-
`ing devices that are linked through a communications net-
`work. In a distributed computing environment, program
`modules may be located in both local and remote memory
`storage devices.
`With reference to FIG. 1, an exemplary system for imple-
`menting the invention includes a general purpose computing
`device in the form of a conventional personal computer 20,
`including a processing unit 21, a system memory 22, and a
`system bus 23 that couples various system components
`including the system memoryto the processing unit 21. The
`system bus 23 may be any of several types of bus structures
`including a memory bus or memory controller, a peripheral
`bus, and a local bus using any of a variety of bus architec-
`tures. System timing is provided by a clock signal (not
`shown) applied to the system bus 23. The system memory
`includes read only memory (ROM) 24 and random access
`memory (RAM) 25. A basic input/output system 26 (BIOS),
`containing the basic routines that helps to transfer informa-
`tion between elements within the personal computer 20,
`such as during start-up, is stored in ROM 24. The personal
`computer 20 further includes a hard disk drive 27 for reading
`from and writing to a hard disk, not shown, a magnetic disk
`drive 28 for reading from or writing to a removable magnetic
`disk 29, and an optical disk drive 30 for reading from or
`writing to a removable optical disk 31 such as a CD-ROM
`or other optical media. The hard disk drive 27, magnetic disk
`drive 28, and optical disk drive 30 are connected to the
`system bus 23 by a hard disk drive interface 32, a magnetic
`disk drive interface 33, and an optical drive interface 34,
`respectively. The drives and their associated computer-
`readable media provide nonvolatile storage of computer
`readable instructions, data structures, program modules and
`other data for the personal computer 20. Although the
`exemplary environment described herein employs a hard
`disk, a removable magnetic disk 29 and a removable optical
`disk 31, it should be appreciated by those skilled in the art
`that other types of computer-readable media which can store
`data that is accessible by a computer, such as magnetic
`cassettes, flash memory cards, digital versatile disks (also
`known as Digital Video Disks or DVDs), Bernoulli
`cartridges, random access memories (RAMs), read only
`memories (ROMs), and the like, may also be used in the
`exemplary operating environment.
`Anumberof program modules may be stored on the hard
`disk, magnetic disk 29, optical disk 31, ROM 24 or RAM 25,
`including an operating system 35, one or more application
`programs 36, other program modules 37, and program data
`38. A user may enter commands and information into the
`personal computer 20 through input devices such as a
`keyboard 40 and pointing device 42. Other input devices
`
`4
`(not shown) mayinclude a microphone, joystick, game pad,
`satellite dish, scanner, or the like. These and other input
`devices are often connected to the processing unit 21
`through a serial port interface 46 that is coupled to the
`system bus, but may be connected by other interfaces, such
`as a parallel port, game port or a universal serial bus (USB).
`A monitor 47 or other type of display device is also
`connected to the system bus 23 via an interface, such as a
`video adapter 48. One or more speakers 57 are also con-
`nected to the system bus 23 via an interface, such as an audio
`adapter 56. In addition to the monitor and speakers, personal
`computers typically include other peripheral output devices
`(not shown), such as printers.
`The personal computer 20 may operate in a networked
`environment using logical connections to one or more
`remote computers, such as remote computers 49 and 60.
`Each remote computer 49 or 60 may be another personal
`computer, a server, a router, a network PC,a peer device or
`other common network node,and typically includes many or
`all of the elements described above relative to the personal
`computer 20, although only a memory storage device 50 or
`61 has been illustrated in FIG. 1. The logical connections
`depicted in FIG. 1 include a local area network (LAN) 51
`and a wide area network (WAN) 52, Such networking
`environments are commonplace in offices, enterprise-wide
`computer networks, intranets and global networks such as
`the Internet. As depicted in FIG. 1, the remote computer 60
`communicates with the personal computer 20 via the local
`area network 51. The remote computer 49 communicates
`with the personal computer 20 via the wide area network 52.
`When used in a LAN networking environment, the per-
`sonal computer 20 is connected to the local network 51
`through a network interface or adapter 53. When used in a
`WAN networking environment, the personal computer 20
`typically includes a modem 54 or other meansfor establish-
`ing communications over the wide area network 52, such as
`the Internet. The modem 54, which may be internal or
`external, is connected to the system bus 23 viathe serial port
`interface 46. In a networked environment, program modules
`depicted relative to the personal computer 20, or portions
`thereof, may be stored in the remote memorystorage device.
`It will be appreciated that the network connections shown
`are exemplary and other meansof establishing a communi-
`cations link between the computers may be used.
`In the present invention a composite documentincluding
`one or more subdocuments visually embedded therein is
`output
`to a display.
`In a present embodiment of the
`invention, a desktop 300 environmentis displayed with one
`or more desktop components 310. Referring to FIG. 2,
`desktop component 310 is shownina first state in which the
`desktop component merely appears as an image on the
`desktop 300, rather than as a window with accompanying
`windows functionality elements such as borders, caption
`bars, etc. This is the default state for all desktop components
`where the pointer 320 is not within a predefined region with
`respect to the desktop component. The concept of regions
`will be described more fully in the discussion of FIG. 6.
`FIG. 3 depicts a desktop component 310 in a secondstate
`in which pointer 320 is displayed completely within an area
`defined by the desktop component. In this situation, a thin
`border 330 is displayed around the desktop component 310.
`In a present embodiment, the thin border 330 has a one-pixel
`width, and is used to visually indicate the boundaries of the
`desktop component. This allows a user to more easily
`position the pointer on the desktop component boundary for
`resizing the desktop component, and is especially helpful
`where there is little contrast between the colors of the
`
`desktop 300 and the desktop component.

`movement of the pointer within region A 606 causes no
`further changein state.
`Returning to state 704, movement of the pointer within
`region B 608 causes a change to state 708, where a thick
`border is displayed. This is the state depicted in FIG. 4.
`Continued movement of the pointer within region C 608
`causes no changeofstate from the state 708. Returning once
`again to the no border state 704, movement of the pointer
`within the region C 610 causes a change of state to the
`caption bar state 710. This is the state depicted in FIG. 5.
`Continued movement of the pointer within the caption bar
`state 610 causes no changeofstate.
`From the thick border state 708, or the caption barstate
`710, movementof the pointer into the thin border region 606
`causes a change to the thin border state 706. Similarly,
`movement of the pointer into the thick border region 608
`causes a change ofstate to the thick border state 708, and
`movement of the pointer into the caption bar region 610
`causes a change of state to the caption bar state 710.
`Additionally, because the caption bar is displayed when in
`the caption bar state 710, movementof the pointer into the
`maintain caption bar state 612 causes a return to the caption
`bar state 710.
`

`FIG. 4 depicts the desktop component310 in a third state
`in which pointer 320 is in close proximity to, or actually
`intersecting, an edge of the desktop component. In this
`situation, a thick border 340 is displayed. In a present
`embodiment, a three-pixel border is used so that the user
`may moreeasily interact with the border, such asfor resizing
`the desktop element.
`FIG. 5 depicts the desktop component 310 in a fourth
`state, in which a caption bar 500 is displayed along an edge
`of the desktop component. In a present embodiment of the
`invention, the caption bar is displayed along the top edge of
`the desktop component for allowing a user to interact with
`the desktop component, such as for moving the desktop
`component on the desktop. In a present embodimentof the
`invention, the caption bar is displayed with a thick border
`340 aroundthe other edges, and is provided with a minimize
`button 510 and a close button 520, for allowing the user to
`respectively minimize and close the desktop component.
`The caption bar is displayed along the top border when
`pointer 320 is in close proximity to the upper edge of the
`desktop component. Those skilled in the art will readily

`FIG. 8 depicts a control for implementing the features of
`the present invention according to the state diagram shown
`in FIG. 6. While, to the user, the appearance on the display
`is of a desktop component 310 having borders and/or a
`caption bar, preferably, these elements are not elements of
`the desktop component. Rather, a border 330 and a caption
`bar 500 are elements of the control 800.
`In a present
`embodiment of the invention,
`the control 800 is imple-
`mented as an ActiveX control referred to as deskmovr. The
`deskmovr control may be used both with desktop compo-
`nents that are windowed objects as well as those that are
`windowless objects. A present embodiment of a desktop
