Abstract:
A mechanism for viewing a portion of a document that overflows a display portion area of an interface is provided. The document is opened using an application. The document is displayed in a display portion of the interface associated with the application. Portions of the document displayed in the display portion of the interface overflow the width of the display area and are obscured thereby forming obscured portions of the document. A determination is made as to whether a section of the document displayed in the display portion of the interface overflow is selected by a user thereby forming a selected section. Responsive to the selected section being one obscured portion of the obscured portions of the document, a separate display window is opened in which the selected section is displayed in its entirety without changing any viewing parameters associated with the interface.

Description:
BACKGROUND 
       [0001]    The present application relates generally to an improved data processing apparatus and method and more specifically to an apparatus and method for viewing portions of document that overflow the viewing area of an interface without changing viewing parameters associated with the interface. 
         [0002]    A graphical user interface is one type of program interface that takes advantage of the computer&#39;s graphics capabilities to make the program easier to use. Well-designed graphical user interfaces may free a user from learning complex command languages. On the other hand, many users find that they work more effectively with a command-driven interface, especially if they already know the command language. 
         [0003]    Graphical user interfaces, such as Microsoft Windows® and the one used by the Apple Macintosh®, feature the following basic components:
       Pointer: A symbol that appears on the display screen and that a user moves to select objects and commands. Usually, the pointer appears as a small angled arrow. Text-processing applications, however, use an I-beam pointer that is shaped like a capital I.   Pointing device: A device, such as a mouse or trackball, that enables a user to select objects on the display screen.   Icons: Small pictures that represent commands, files, or windows. By moving the pointer to the icon and pressing a mouse button, a user may execute a command or convert the icon into a window. A user may also move the icons around the display screen as if they were real objects on your desk.   Desktop: The area on the display screen where icons are grouped is often referred to as the desktop because the icons are intended to represent real objects on a real desktop.   Windows: A user may divide the screen into different areas. In each window, a user may run a different program or display a different file. A user may move windows around the display screen, and change their shape and size at will.   Menus: Most graphical user interfaces let a user execute commands by selecting a choice from a menu.       
 
         [0010]    In addition to their visual components, graphical user interfaces also make it easier to move data from one application to another. A true GUI includes standard formats for representing text and graphics. Because the formats are well-defined, different programs that run under a common GUI can share data. This makes it possible, for example, to copy a graph created by a spreadsheet program into a document created by a word processor. 
         [0011]    Many DOS programs include some features of GUIs, such as menus, but are not graphics based. Such interfaces are sometimes called graphical character-based user interfaces to distinguish them from true GUIs. 
       SUMMARY 
       [0012]    In one illustrative embodiment, a method, in a data processing system, is provided for viewing a portion of a document that overflows a display portion area of an interface. The illustrative embodiment opens the document using an application. The illustrative embodiment displays the document in a display portion of the interface associated with the application.

     DETAILED DESCRIPTION 
       [0023]    The illustrative embodiments provide a mechanism for viewing portions of document that overflow the viewing area of an interface without changing viewing parameters associated with the interface. If the content of a document flows past the viewable area of the display in which the document is being viewed, a user may select a portion of the content at which time an overflow viewing window will appear that displays the entire selected portion including the portion originally obscured. 
         [0024]    As will be appreciated by one skilled in the art, the present invention may be embodied as a system, method, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product embodied in any tangible medium of expression having computer usable program code embodied in the medium. 
         [0025]    Any combination of one or more computer usable or computer readable medium(s) may be utilized. The computer-usable or computer-readable medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CDROM), an optical storage device, a transmission media such as those supporting the Internet or an intranet, or a magnetic storage device. Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-usable medium may include a propagated data signal with the computer-usable program code embodied therewith, either in baseband or as part of a carrier wave. The computer usable program code may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, radio frequency (RF), etc. 
         [0026]    Computer program code for carrying out operations of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java™, Smalltalk™, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). 
         [0027]    The illustrative embodiments are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to the illustrative embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
         [0028]    These computer program instructions may also be stored in a computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block or blocks. 
         [0029]    The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
         [0030]    The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions. 
         [0031]    The illustrative embodiments provide for viewing portions of document that overflow the viewing area of an interface without changing viewing parameters associated with the interface. A user may select a portion of content that is obscured by display parameters of an application in which the text is displayed. By selecting the portion of content, an overflow viewing window is revealed to shows the displayed content as well as any obscured content. The user may be able to change the parameters of the overflow viewing window as well as change parameters associated with the display area. If in changing parameters associated with the display the entire width of the content is shown in the display area, then the overflow viewing window automatically closes. Further if the user deselects the selected area or selects another portion of content that is that is obscured by the display parameters of the application, then a new overflow viewing window is revealed. 
         [0032]    Thus, the illustrative embodiments may be utilized in many different types of data processing environments including a distributed data processing environment, a single data processing device, or the like. In order to provide a context for the description of the specific elements and functionality of the illustrative embodiments,  FIGS. 1 and 2  are provided hereafter as example environments in which aspects of the illustrative embodiments may be implemented. While the description following  FIGS. 1 and 2  will focus primarily on a single data processing device implementation overflow viewing window mechanism, this is only an example and is not intended to state or imply any limitation with regard to the features of the present invention. To the contrary, the illustrative embodiments are intended to include distributed data processing environments and embodiments in which portions of document that overflow the viewing area of an interface are displayed without changing viewing parameters associated with the interface. 
         [0033]    With reference now to the figures and in particular with reference to  FIGS. 1-2 , example diagrams of data processing environments are provided in which illustrative embodiments of the present invention may be implemented. It should be appreciated that  FIGS. 1-2  are only examples and are not intended to assert or imply any limitation with regard to the environments in which aspects or embodiments of the present invention may be implemented. Many modifications to the depicted environments may be made without departing from the spirit and scope of the present invention. 
         [0034]    With reference now to the figures,  FIG. 1  depicts a pictorial representation of an example distributed data processing system in which aspects of the illustrative embodiments may be implemented. Distributed data processing system  100  may include a network of computers in which aspects of the illustrative embodiments may be implemented. The distributed data processing system  100  contains at least one network  102 , which is the medium used to provide communication links between various devices and computers connected together within distributed data processing system  100 . The network  102  may include connections, such as wire, wireless communication links, or fiber optic cables. 
         [0035]    In the depicted example, server  104  and server  106  are connected to network  102  along with storage unit  108 . In addition, clients  110 ,  112 , and  114  are also connected to network  102 . These clients  110 ,  112 , and  114  may be, for example, personal computers, network computers, or the like. In the depicted example, server  104  provides data, such as boot files, operating system images, and applications to the clients  110 ,  112 , and  114 . Clients  110 ,  112 , and  114  are clients to server  104  in the depicted example. Distributed data processing system  100  may include additional servers, clients, and other devices not shown. 
         [0036]    In the depicted example, distributed data processing system  100  is the Internet with network  102  representing a worldwide collection of networks and gateways that use the Transmission Control Protocol/Internet Protocol (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, governmental, educational and other computer systems that route data and messages. Of course, the distributed data processing system  100  may also be implemented to include a number of different types of networks, such as for example, an intranet, a local area network (LAN), a wide area network (WAN), or the like. As stated above,  FIG. 1  is intended as an example, not as an architectural limitation for different embodiments of the present invention, and therefore, the particular elements shown in  FIG. 1  should not be considered limiting with regard to the environments in which the illustrative embodiments of the present invention may be implemented. 
         [0037]    With reference now to  FIG. 2 , a block diagram of an example data processing system is shown in which aspects of the illustrative embodiments may be implemented. Data processing system  200  is an example of a computer, such as client  110  in  FIG. 1 , in which computer usable code or instructions implementing the processes for illustrative embodiments of the present invention may be located. 
         [0038]    In the depicted example, data processing system  200  employs a hub architecture including north bridge and memory controller hub (NB/MCH)  202  and south bridge and input/output (I/O) controller hub (SB/ICH)  204 . Processing unit  206 , main memory  208 , and graphics processor  210  are connected to NB/MCH  202 . Graphics processor  210  may be connected to NB/MCH  202  through an accelerated graphics port (AGP). 
         [0039]    In the depicted example, local area network (LAN) adapter  212  connects to SB/ICH  204 . Audio adapter  216 , keyboard and mouse adapter  220 , modem  222 , read only memory (ROM)  224 , hard disk drive (HDD)  226 , CD-ROM drive  230 , universal serial bus (USB) ports and other communication ports  232 , and PCI/PCIe devices  234  connect to SB/ICH  204  through bus  238  and bus  240 . PCI/PCIe devices may include, for example, Ethernet adapters, add-in cards, and PC cards for notebook computers. PCI uses a card bus controller, while PCIe does not. ROM  224  may be, for example, a flash basic input/output system (BIOS). 
         [0040]    HDD  226  and CD-ROM drive  230  connect to SB/ICH  204  through bus  240 . HDD  226  and CD-ROM drive  230  may use, for example, an integrated drive electronics (IDE) or serial advanced technology attachment (SATA) interface. Super I/O (SIO) device  236  may be connected to SB/ICH  204 . 
         [0041]    An operating system runs on processing unit  206 . The operating system coordinates and provides control of various components within the data processing system  200  in  FIG. 2 . As a client, the operating system may be a commercially available operating system such as Microsoft® Windows® XP (Microsoft and Windows are trademarks of Microsoft Corporation in the United States, other countries, or both). An object-oriented programming system, such as the Java™ programming system, may run in conjunction with the operating system and provides calls to the operating system from Java™ programs or applications executing on data processing system  200  (Java is a trademark of Sun Microsystems, Inc. in the United States, other countries, or both). 
         [0042]    As a server, data processing system  200  may be, for example, an IBM® eServer™ System p® computer system, running the Advanced Interactive Executive (AIX®) operating system or the LINUX® operating system (eServer, System p, and AIX are trademarks of International Business Machines Corporation in the United States, other countries, or both while LINUX is a trademark of Linus Torvalds in the United States, other countries, or both). Data processing system  200  may be a symmetric multiprocessor (SMP) system including a plurality of processors in processing unit  206 . Alternatively, a single processor system may be employed. 
         [0043]    Instructions for the operating system, the object-oriented programming system, and applications or programs are located on storage devices, such as HDD  226 , and may be loaded into main memory  208  for execution by processing unit  206 . The processes for illustrative embodiments of the present invention may be performed by processing unit  206  using computer usable program code, which may be located in a memory such as, for example, main memory  208 , ROM  224 , or in one or more peripheral devices  226  and  230 , for example. 
         [0044]    A bus system, such as bus  238  or bus  240  as shown in  FIG. 2 , may be comprised of one or more buses. Of course, the bus system may be implemented using any type of communication fabric or architecture that provides for a transfer of data between different components or devices attached to the fabric or architecture. A communication unit, such as modem  222  or network adapter  212  of  FIG. 2 , may include one or more devices used to transmit and receive data. A memory may be, for example, main memory  208 , ROM  224 , or a cache such as found in NB/MCH  202  in  FIG. 2 . 
         [0045]    Those of ordinary skill in the art will appreciate that the hardware in  FIGS. 1-2  may vary depending on the implementation. Other internal hardware or peripheral devices, such as flash memory, equivalent non-volatile memory, or optical disk drives and the like, may be used in addition to or in place of the hardware depicted in  FIGS. 1-2 . Also, the processes of the illustrative embodiments may be applied to a multiprocessor data processing system, other than the SMP system mentioned previously, without departing from the spirit and scope of the present invention. 
         [0046]    Moreover, the data processing system  200  may take the form of any of a number of different data processing systems including client computing devices, server computing devices, a tablet computer, laptop computer, telephone or other communication device, a personal digital assistant (PDA), or the like. In some illustrative examples, data processing system  200  may be a portable computing device which is configured with flash memory to provide non-volatile memory for storing operating system files and/or user-generated data, for example. Essentially, data processing system  200  may be any known or later developed data processing system without architectural limitation. 
         [0047]    Turning next to  FIG. 3 , a block diagram of an application is depicted in accordance with a preferred embodiment of the present invention. An application may be any application that is used to navigate or view information or data in a distributed database. 
         [0048]    In this example, application  300  includes a user interface  302 , which may be a graphical user interface (GUI) that allows the user to interface or communicate with application  300 . User interface  302  provides for selection of various functions through menus  304  and allows for navigation through navigation  306 . For example, menu  304  may allow a user to perform various functions, such as saving a file, opening a new window, displaying a history, and entering a URL. Navigation  306  allows for a user to navigate various pages and to select web sites for viewing. For example, navigation  306  may allow a user to see a previous page or a subsequent page relative to the present page. Preferences such as those illustrated in  FIG. 3  may be set through preferences  308 . 
         [0049]    Communications  310  is the mechanism with which application  300  receives documents and other resources from a network, such as the Internet, Intranet, or other network server. Further, communications  310  is used to send or upload documents and resources onto a network. In the depicted example, communication  310  uses HTTP; however, other protocols may be used depending on the implementation. Documents that are received by application  300  are processed by language interpretation  312 , which includes HTML unit  314 , JavaScript™ unit  316 , and embedded codes  326 . Language interpretation  312  will process a document for presentation on graphical display  318 . In particular, HTML statements are processed by HTML unit  314  for presentation while JavaScript statements are processed by JavaScript unit  316 . Language interpretation  312  may also process codes that are embedded within a document using embedded codes  326 . Graphical display  318  includes layout unit  320 , rendering unit  322 , and window management  324 . These units are involved in presenting documents to a user based on results from language interpretation  312 . 
         [0050]    Application  300  is presented as an example of a program in which the present invention may be embodied. Application  300  is not meant to imply architectural limitations to the present invention. Presently available applications may include additional functions not shown or may omit functions shown in application  300 . 
         [0051]      FIG. 4  is a diagram illustrating the display of a window on a display of a data processing system in accordance with an illustrative embodiment. As shown in  FIG. 4 , content  402  of a document is retrieved over a computer network in response to a user request is displayed in window  404  that contains multiple interface elements outside of a document display area  406 . These interface elements may include title bar  408  comprising program icon  410 , “Close” button  412 , “Maximize/Restore Down” button  414 , and “Minimize” button  416 , menu bar  418 , tool bar  420 , and status bar  422 . These interface elements may also include scroll bars  424  and  425  and zoom control  426  which are used to control the viewable portions of document display area  406 . Names of exemplary interface elements follow naming conventions used in the many known applications, such as Microsoft® Internet Explorer®, Microsoft® Office®, or the like. Window  404  may also include resizable borders  428 . 
         [0052]    In the example shown on  FIG. 4 , content  402  displayed in document display area  406  is wider than the current size of document display area  406 , which results in portions of content  402  flowing past the right hand side of document display area  406 . In order to view the entire width of content  402 , a user may perform any number of operations, such as using scroll bar  425  to scroll the content to the right, maximizing window  404  to the maximum displayable area of the screed on which window  404  is displayed using “Maximize/Restore Down” button  414 , resizing window  404  using resizable borders  428 , or resizing the viewable size of document display area  406  using zoom control  426 . However each of these operations may cause other consequences to occur, such as the beginning of content  402  flowing past the left hand side of document display area  406 , maximizing the display causing other windows being obscured, or zooming the viewable size of document display area  406  causing the text or pictures of content  402  to be very small. 
         [0053]      FIG. 5  is a diagram illustrating an overflow viewing window mechanism used in conjunction with a display of a window on a display of a data processing system in accordance with an illustrative embodiment. As shown in  FIG. 5 , content  502  of a document is retrieved over a computer network in response to a user request is displayed in window  504  that contains multiple interface elements outside of a document display area  506 . Similar to  FIG. 4 , the interface elements may include title bar  508  comprising program icon  510 , “Close” button  512 , “Maximize/Restore Down” button  514 , and “Minimize” button  516 , menu bar  518 , tool bar  520 , and status bar  522 . These interface elements may also include scroll bars  524  and  525  and zoom control  526  which are used to control the viewable portions of document display area  506 . Names of exemplary interface elements follow naming conventions used in the many known applications, such as Microsoft® Internet Explorer®, Microsoft® Office®, or the like. Window  504  may also include resizable borders  528 . 
         [0054]    In the example shown on  FIG. 5 , content  502  displayed in document display area  506  is wider than the current size of document display area  506 , which results in portions of content  502  flowing past the right hand side of document display area  506 . However, in this example, in order to view the entire width of a particular portion of content  502 , a user is not required to change viewing parameter options of the application, such as using scroll bar  525  to scroll the content to the right, maximizing window  504  to the maximum displayable area of the screen on which window  504  is displayed using “Maximize/Restore Down” button  514 , resizing window  504  using resizable borders  528 , or resizing the viewable size of document display area  506  using zoom control  526 . 
         [0055]    In this illustrative embodiment, even though portions of content  502  flow past the right hand side of document display area  506 , the application knows the placement of the content relative to all of content  502  and content elements associated with content  502  in the document. When the application detects that a user has moved cursor  530  over a paragraph of content  502 , an overflow viewing window mechanism of the application compares the content of the complete paragraph with the currently displayed content displayed in document display area  506 . In this example, if the complete paragraph extends past the right-hand side of document display area  506 , then the overflow viewing window mechanism displays overflow viewing window  532 . Overflow viewing window  532  is a window that displays then entire text in the paragraph including the section that flows past the right-hand side of document display area  506 . While this example illustrates text that is obscured on the right hand side of document display area  506 , the illustrative embodiments are not limited to portions of documents that are only obscured on the right-hand side. That is, one of ordinary skill in the art would recognize that the illustrative embodiment may be used with any portions of a document that are obscured whatsoever by a display area of an interface. 
         [0056]    Overflow viewing window  532  may be a static window that displays the entire text of the paragraph in a fixed window area, may be a dynamic sizing window that displays the entire text of the paragraph in an automatically-sized area based on the constraints of the display, or may be a dynamic sizing window that the user is able to adjust using window handles  534 . While this example illustrates the use of overflow viewing window  532  with respect to a text document, the illustrative embodiments are not limited to only text documents. That is, the processes of the illustrative embodiments may be applied to photos, illustrations, charts, or the like, or any combination of those types of contents, without departing from the spirit and scope of the present invention. 
         [0057]    Further, if the user moves cursor  530  to another paragraph of content  502 , then the application detects the change of content and performs the operation described above for the new selected paragraph. If the user moves the cursor out of document display area  506  while overflow viewing window  532  is still active, then overflow viewing window  532  remains active. However, if, during the time that overflow viewing window  532  is active, the user changes an application parameter in order to display the entire width of content  502  by utilizing an operation, such as by maximizing window  504  to the maximum displayable area of the interface, resizing window  504  using resizable borders  528 , resizing the viewable size of document display area  506  using zoom control  526 , or the like, then overflow viewing window  532  would be closed. 
         [0058]    Thus, the illustrative embodiments provide a mechanism for viewing portions of document that overflow the viewing area of an interface without changing viewing parameters associated with the interface. If the content of a document flows past the viewable area of the display in which the document is being viewed, a user may select a portion of the content at which time an overflow viewing window will appear that displays the entire selected portion including the portion originally obscured. 
         [0059]      FIG. 6  depicts the operation of an overflow viewing window mechanism in accordance with an illustrative embodiment. As the operation begins, an application is launched that uses an overflow viewing window mechanism (step  602 ). Once a document has been opened in the interface of the application, the display portion of the interface displays all or a portion of the document (step  604 ). The overflow viewing window mechanism of the application then determines if the user has selected a section of the document that flows over the viewable width portion of the interface and is thus obscured (step  606 ). If at step  606 , the user has not selected a section of the document that flows over the viewable width portion of the interface, then the operation returns to step  604 . 
         [0060]    If at step  606  the user selects a section of the document that flows over the viewable width portion of the interface, then the overflow viewing window mechanism opens an overflow viewing window and displays the entire selected section of the document that flows over the viewable width portion of the interface (step  608 ). Then the overflow viewing window mechanism may either determine if the user has selected a viewing parameter option of the application that causes the overflow viewing window to no longer be needed (step  610 ), determine if the user has de-selected the selected section of the document (step  612 ), or if the user has selected another section of the document (step  614 ). If at step  610  the user has not selected a viewing parameter option that causes the overflow viewing window to no longer be needed, if at step  612  the user has failed to de-select the selected section, or if at step  614  the user has failed to select another portion of the document, then the operation returns to step  608 . 
         [0061]    If at step  610  the user has selected a viewing parameter option that causes the overflow viewing window to no longer be needed, then the overflow viewing window mechanism closes the overflow viewing window (step  616 ) with the operation returning to step  604  thereafter. If at step  612  the user de-selects the selected section of the document, then the overflow viewing window mechanism closes the overflow viewing window (step  616 ) with the operation returning to step  604  thereafter. However, if at step  614  the user selects another section of the document, then the overflow viewing window mechanism closes the current overflow viewing window (step  618 ) and immediately proceeds to step  608  where a new overflow viewing window is opened and the entire newly selected section of the document that flows over the viewable width portion of the interface is displayed. 
         [0062]    Thus, the illustrative embodiments provide for viewing portions of document that overflow the viewing area of an interface without changing viewing parameters associated with the interface. A user may select a portion of content that is obscured by display parameters of an application in which the text is displayed. By selecting the portion of content, an overflow viewing window is revealed to show the displayed content as well as any obscured content. The user may be able to change the parameters of the overflow viewing window as well as change parameters associated with the display area. If in changing parameters associated with the display, the entire width of the content is shown in the display area, then the overflow viewing window automatically closes. Further, if the user deselects the selected area or selects another portion of content that is obscured by the display parameters of the application, then a new overflow viewing window is revealed. 
         [0063]    As noted above, it should be appreciated that the illustrative embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. In one example embodiment, the mechanisms of the illustrative embodiments are implemented in software or program code, which includes but is not limited to firmware, resident software, microcode, etc. 
         [0064]    A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution. 
         [0065]    Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers. Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modems and Ethernet cards are just a few of the currently available types of network adapters.
