Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Technical Field  
           [0002]    The present invention is directed to word processing application programs. More specifically, the present invention is directed to a system and method of managing items on a clipboard.  
           [0003]    2. Description of Related Art  
           [0004]    Most word processing application programs allow a user to remove or copy a block of text, an audio or video clip, graphics etc. from a document and to transfer them to another location in the document or to another document altogether. To remove an item (i.e., a block of text, an audio or video clip, or graphics etc.) from the document is generally referred to as “cut” whereas to copy the item is referred to as “copy”. To transfer the cut or copied item to another location of the document or to another document is referred to as “paste”.  
           [0005]    When an item is cut or copied from a document, it is ordinarily transferred to a temporary buffer called a clipboard. This allows the user to later paste the item at the other location in the document or in the other document. Note that copying and cutting an item from a document will henceforth be referred to as copying the item onto the clipboard or plainly “to copy”.  
           [0006]    Presently, a plurality of items may be copied onto the clipboard. However, once there the items may not be manipulated (e.g., they may not be consolidated into one item).  
           [0007]    Consequently, there is a need for a system and method of managing items on a clipboard.  
         SUMMARY OF THE INVENTION  
         [0008]    The present invention provides a system and method of enabling a user to manage items such as text, graphics image, audio clips, video clips etc. on a clipboard. The system and method include displaying a window having at least one option for managing the items on the clipboard and allowing the user to assert the option to manage the items.  
           [0009]    In another embodiment, the present invention provides a method and system to indicate a selected item at a location in a document displayed in a graphical user interface with a scrollbar. The method and system include selecting the item, determining whether the item is an object of a particular type and displaying an icon representing the object at a location in the scrollbar corresponding to the location of the highlighted item.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0020]    With reference now to the figures, FIG. 1 depicts a pictorial representation of a network of data processing systems in which the present invention may be implemented. Network data processing system  100  is a network of computers in which the present invention may be implemented. Network data processing system  100  contains a network  102 , which is the medium used to provide communications links between various devices and computers connected together within network data processing system  100 . Network  102  may include connections, such as wire, wireless communication links, or fiber optic cables.  
         [0021]    In the depicted example, server  104  is connected to network  102  along with storage unit  106 . In addition, clients  108 ,  110 , and  112  are connected to network  102 . These clients  108 ,  110 , and  112  may be, for example, personal computers or network computers. In the depicted example, server  104  provides data, such as boot files, operating system images, and applications to clients  108 ,  110  and  112 . Clients  108 ,  110  and  112  are clients to server  104 . Network data processing system  100  may include additional servers, clients, and other devices not shown. In the depicted example, network data processing system  100  is the Internet with network  102  representing a worldwide collection of networks and gateways that use the TCP/IP suite of protocols to communicate with one another. At the heart of the Internet is a backbone of high-speed data communication lines between major nodes or host computers, consisting of thousands of commercial, government, educational and other computer systems that route data and messages. Of course, network data processing system  100  also may be implemented as a number of different types of networks, such as for example, an intranet, a local area network (LAN), or a wide area network (WAN). FIG. 1 is intended as an example, and not as an architectural limitation for the present invention.  
         [0022]    Referring to FIG. 2, a block diagram of a data processing system that may be implemented as a server, such as server  104  in FIG. 1, is depicted in accordance with a preferred embodiment of the present invention. Data processing system  200  may be a symmetric multiprocessor (SMP) system including a plurality of processors  202  and  204  connected to system bus  206 . Alternatively, a single processor system may be employed. Also connected to system bus  206  is memory controller/cache  208 , which provides an interface to local memory  209 . I/O bus bridge  210  is connected to system bus  206  and provides an interface to I/O bus  212 . Memory controller/cache  208  and I/O bus bridge  210  may be integrated as depicted.  
         [0023]    Peripheral component interconnect (PCI) bus bridge  214  connected to I/O bus  212  provides an interface to PCI local bus  216 . A number of modems may be connected to PCI local bus  216 . Typical PCI bus implementations will support four PCI expansion slots or add-in connectors. Communications links to network computers  108 ,  110  and  112  in FIG. 1 may be provided through modem  218  and network adapter  220  connected to PCI local bus  216  through add-in boards.  
         [0024]    Additional PCI bus bridges  222  and  224  provide interfaces for additional PCI local buses  226  and  228 , from which additional modems or network adapters may be supported. In this manner, data processing system  200  allows connections to multiple network computers. A memory-mapped graphics adapter  230  and hard disk  232  may also be connected to I/O bus  212  as depicted, either directly or indirectly.  
         [0025]    Those of ordinary skill in the art will appreciate that the hardware depicted in FIG. 2 may vary. For example, other peripheral devices, such as optical disk drives and the like, also may be used in addition to or in place of the hardware depicted. The depicted example is not meant to imply architectural limitations with respect to the present invention.  
         [0026]    The data processing system depicted in FIG. 2 may be, for example, an IBM e-Server pseries system, a product of International Business Machines Corporation in Armonk, N.Y., running the Advanced Interactive Executive (AIX) operating system or LINUX operating system.  
         [0027]    With reference now to FIG. 3, a block diagram illustrating a data processing system is depicted in which the present invention may be implemented. Data processing system  300  is an example of a client computer. Data processing system  300  employs a peripheral component interconnect (PCI) local bus architecture. Although the depicted example employs a PCI bus, other bus architectures such as Accelerated Graphics Port (AGP) and Industry Standard Architecture (ISA) may be used. Processor  302  and main memory  304  are connected to PCI local bus  306  through PCI bridge  308 . PCI bridge  308  also may include an integrated memory controller and cache memory for processor  302 . Additional connections to PCI local bus  306  may be made through direct component interconnection or through add-in boards. In the depicted example, local area network (LAN) adapter  310 , SCSI host bus adapter  312 , and expansion bus interface  314  are connected to PCI local bus  306  by direct component connection. In contrast, audio adapter  316 , graphics adapter  318 , and audio/video adapter  319  are connected to PCI local bus  306  by add-in boards inserted into expansion slots. Expansion bus interface  314  provides a connection for a keyboard and mouse adapter  320 , modem  322 , and additional memory  324 . Small computer system interface (SCSI) host bus adapter  312  provides a connection for hard disk drive  326 , tape drive  328 , and CD-ROM drive  330 . Typical PCI local bus implementations will support three or four PCI expansion slots or add-in connectors.  
         [0028]    An operating system runs on processor  302  and is used to coordinate and provide control of various components within data processing system  300  in FIG. 3. The operating system may be a commercially available operating system, such as Windows XP, which is available from Microsoft Corporation. An object oriented programming system such as Java may run in conjunction with the operating system and provide calls to the operating system from Java programs or applications executing on data processing system  300 . “Java” is a trademark of Sun Microsystems, Inc. Instructions for the operating system, the object-oriented operating system, and applications or programs are located on storage devices, such as hard disk drive  326 , and may be loaded into main memory  304  for execution by processor  302 .  
         [0029]    Those of ordinary skill in the art will appreciate that the hardware in FIG. 3 may vary depending on the implementation. Other internal hardware or peripheral devices, such as flash ROM (or equivalent nonvolatile memory) or optical disk drives and the like, may be used in addition to or in place of the hardware depicted in FIG. 3. Also, the processes of the present invention may be applied to a multiprocessor data processing system.  
         [0030]    As another example, data processing system  300  may be a stand-alone system configured to be bootable without relying on some type of network communication interface, whether or not data processing system  300  comprises some type of network communication interface. As a further example, data processing system  300  may be a Personal Digital Assistant (PDA) device, which is configured with ROM and/or flash ROM in order to provide non-volatile memory for storing operating system files and/or user-generated data.  
         [0031]    The depicted example in FIG. 3 and above-described examples are not meant to imply architectural limitations. For example, data processing system  300  may also be a notebook computer or hand held computer in addition to taking the form of a PDA. Data processing system  300  also may be a kiosk or a Web appliance.  
         [0032]    The present invention provides an apparatus, system and method of manipulating items on a clipboard. The invention may be local to client systems  108 ,  110  and  112  of FIG. 1 or to the server  104  or to both the server  104  and clients  108 ,  110  and  112  and may reside on any data storage medium (i.e., floppy disk, compact disk, hard disk, ROM, RAM, etc.) used by a computer system.  
         [0033]    Presently, when a viewer is using a word processing application program to view a document and the user desires to copy an item from the document, the user has to first select or highlight the item. In certain word processing systems, such as Microsoft® Word 2002, a user may select additional items by holding down the control (ctrl) key while selecting or highlighting the items. After selecting or highlighting all the desired items, the user may click on the “copy” icon or the “cut” icon in the tool bar of the word processing application program to copy them onto the clipboard. The present invention uses the same principle to select multiple items to be copied.  
         [0034]    [0034]FIG. 4 depicts a computer screen  400  displaying a document with different selected items. The screen  400  includes a scroll bar  405 . The scroll bar  405  has a scroll bar slider  415  and sections  410 ,  420  and  425 . Sections  420  and  425  indicate via icons the selected items. For example, if the highlighted item is an audio clip (see audio clip  435 ), the section may have a speaker icon as shown in section  420 . Likewise, if the highlighted item is a video clip (see video clip  440 ), the section may have a video or multimedia icon as shown in section  425 . Highlighted blocks of text (e.g., block of text  430 ) may be indicated as shown by section  410 .  
         [0035]    After the user selects all the desired items, the user may, as customary, asserts the “cut” or “copy” icon to copy the selected items onto the clipboard. Further, in cases where the user, after selecting a plurality of items, decides instead to copy only one of the selected items, the user need not un-select the unwanted items. Rather, the user may right click on the icon next to the desired item and copy the item onto the clipboard.  
         [0036]    [0036]FIG. 5 depicts a clipboard on which a plurality of copied items is posted. The clipboard has a scrollbar  505  that includes sections  510 ,  520  and  525 . These sections perform the same functions as sections  410 ,  420  and  425  in FIG. 4. That is, if the section corresponds to a copied block of text (e.g., block of text  530 ), then the section is highlighted as shown by section  510 . If, on the other hand, the section corresponds to a copied audio clip (e.g., audio clip  535 ), then the section contains an audio icon as shown by section  520 . If the section corresponds to a copied video clip instead, then the section contains a video icon as illustrated by section  525 .  
         [0037]    The clipboard  500  also contains buttons  550 ,  560 ,  570 ,  580  and  590 . Button  550  is used to paste all items on the clipboard into a document. Generally, the items will be pasted in the order in which they were posted. However, a user may reorder or rearrange the items by asserting “reorder” button  570 . When the button  570  is asserted, FIG. 6 will pop-open. FIG. 6 instructs the user to left-click on the items to be reordered in the order they are to be reordered. After doing so, the user may assert “done” button  605  to reorder the items. Alternatively, the user may manually select and reorder each item individually.  
         [0038]    “Paste one or more” button  560  allows a user to select one or more items from the clipboard to paste in a document. Particularly, when button  560  is asserted, FIG. 7 will pop-open. FIG. 7 instructs the user to select items in the order the user desires them to be pasted. When the user has finished selecting the items, the user may assert on “done” button  705  to have the items pasted in the document.  
         [0039]    As the name suggests “clear all” button  580  may be used to delete all items that are on the clipboard. Note that although a video and an audio icon are used to explain the invention, the invention is not thus restricted. For example, a document icon may be used to indicate that a whole document is selected or is on the clipboard. Likewise, a graphics icon may be used to indicate that a graphics image is selected or is on the clipboard etc. Thus, the video and audio icons are used for illustrative purposes only.  
         [0040]    [0040]FIG. 8 is a flow chart of a process that may be used to implement the invention. The process starts as soon as a user selects an item to copy. When this occurs, a check will be made to determine the object type of the selected item. The object type may be an element of the subject document or it may be a reference to a file. If the object type is not a referenced file but a component of the document, there will not be a file extension, as in the case where a block of text is selected from a document, then the section of the scrollbar that corresponds to the location of the selected block of text in the document will be highlighted. If the object type is a reference to a file, and the file type indicates that the file is an audio file (i.e., .WAV), then a speaker icon may be inserted in the section in the scrollbar corresponding to the location of the audio clip in the document. Likewise, a multimedia icon or a graphics icon etc. may be inserted in the section of the scrollbar corresponding to a multimedia object or a graphics object etc., respectively and the process returns to step  805  (steps  800 ,  805  and  810 ).  
         [0041]    [0041]FIG. 9 is a flow chart of a process that may be used to implement the invention. The process starts when a word processor is accessed (step  900 ). Then a check is continually being made to determine whether the clipboard is to be displayed. If so, FIG. 5 is displayed. In FIG. 5, as mentioned before, options are given to the user to either paste all or one or a few of the items on the clipboard in the document. If the user selects to paste all, then all the items will be pasted in the document. If the user chooses to paste one or a few of the items, then the chosen items will be pasted. In the case where more than one item is chosen, the items will be pasted in the order they were selected and the process will return to step  904  (steps  900 ,  902 ,  904 ,  906 ,  908 ,  910  and  912 ).  
         [0042]    From FIG. 5, the user may reorder the items on the clipboard or altogether delete them from the clipboard. If the user decides to reorder the items, they will be reordered in the order the user selected them (steps  900 .  902 ,  904 ,  914 ,  916 ,  918  and  920 ).  
         [0043]    The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
