Standardized and application-independent graphical user interface
components implemented with web technology
Abstract
The present invention generates graphical user interface (GUI)
components with GUI regions on a GUI display using web technology
such that the GUI components are substantially independent of the
host application. The host application defines a respective size
and a respective location for each GUI region on the GUI display.
The host application also instantiates a corresponding web browser
for each GUI region. Each corresponding browser retrieves and
executes an associated web page that defines the appearance and/or
the functionality of a GUI region. The web page is written in a
standard high-level language such as hypertext markup language such
that the appearance and functionality of the GUI regions may be
easy to create and modify. Because the web page defining a GUI
region can be located anywhere on the world wide web, the
functionality of the GUI regions is extensible beyond the
capabilities of the host terminal running the host application. In
addition, the corresponding browser determines an appropriate time
for performing the corresponding functionality of each GUI region.
The corresponding browser may also bind to an object model within
the host application to provide the host application functions via
a GUI region.

Description
[0001] This application claims priority to U.S. application Ser.
No. 09/084,436, filed on May 27, 1998 and issued on Dec. 17, 2002
as U.S. Pat. No. 6,496,203.
TECHNICAL FIELD
[0002] This invention relates to software for creating user
interface components on a graphical user interface (GUI) display
such as a computer screen, and more particularly, to graphical user
interface (GUI) regions that are created by a host application
using browsers and web pages such that the appearance and
functionality of the GUI regions are substantially independent of
the host application and such that the GUI regions may be created
using a standardized programming language.
BACKGROUND OF THE INVENTION
[0003] A user of a computer, whether the computer is a PC or a
workstation, has by now interacted with graphical interface
components on the computer screen. For example, referring to FIG.
1, a graphical user interface (GUI) display 17 such as a computer
screen commonly displays a toolbar 16 within a word processor
application. The toolbar 16 of the example is comprised of GUI
regions such as buttons. A GUI region is any area on the computer
screen that, when interacted with by the user, provides a
functionality of the application.
[0004] In the word processor application for example, the toolbar
16 has GUI regions that, when interacted with, activate macros or
other common functions associated with the word processor
application. Each GUI region has an identifying appearance on the
toolbar and provides a corresponding functionality when that GUI
region is interacted with. For example, a GUI region represented by
a picture of scissors provides the functionality of "cut text
selection" when clicked on. The user may interact with the GUI
region, for example, by clicking on the GUI region with a mouse or
staring at that GUI region for a predetermined time period or by
any other means that are known to one of ordinary skill in the
art.
[0005] The toolbar 16 of FIG. 1 is comprised of three GUI regions
including a first GUI region 18 for "opening a text file", a second
GUI region 20 for "cutting text", and a third GUI region 22 for
"copying text." The prior art GUI regions, including the appearance
and functionality of the GUI regions, are created by a host
application code which is implemented in a programming language
such as C++ or by a graphics language program such as VISUAL
BASIC.RTM.. Referring to FIG. 1 for example, a host application 12,
which may be a word processor application, includes a GUI component
module 14 which creates the toolbar 16 of the prior art on the GUI
display 17. Significantly, for the prior art toolbar 16, the code
of the host application defines the appearance and functionality of
the GUI regions 18, 20, and 22.
[0006] Thus, in the prior art, several disadvantages exist. First,
in order to create the appearance and functionality of the GUI
regions, the creator needs to be familiar with programming
languages that are not high-level user-friendly standardized
languages. Furthermore, the host application code typically needs
to be compiled before running the host application for creating the
GUI regions.
[0007] In the prior art, in order to change the appearance and
functionality of the GUI regions, the host application code is
rewritten with the same programming language used for the original
host application code, and this host application code is recompiled
into an executable code before running the host application. Such
changes to the GUI regions may be desirable for upgrading the
appearance and functionality of the regions. However, most users of
the host application may not easily comprehend such programming
languages such as C++ or VISUAL BASIC.RTM. in order to be able to
modify the GUI regions. In addition, the host application code for
all users desiring upgrades would need to be changed and
recompiled, or alternatively, such users may be forced to
repurchase an upgraded host application.
[0008] GUI components such as the toolbar 16 is comprised of at
least one GUI region such as the buttons of the toolbar 16. Some
host applications include a set of available GUI components or GUI
regions, and the user can select which GUI components or GUI
regions will appear on the GUI display. However, the appearance and
functionality of each of the available GUI components and GUI
regions are still determined by the host application code.
[0009] Accordingly, a need exists for allowing the appearance and
functionality of GUI regions of GUI components to be created and
changed without rewriting the host application code. The present
invention is described with respect to example GUI regions
comprising a toolbar GUI component within a word processing host
application. However, one of ordinary skill in the art should
appreciate that the present invention may be practiced for any
other type of GUI regions within any other type of host application
from the description herein.
SUMMARY OF THE INVENTION
[0010] Accordingly to the present invention, GUI regions are
generated using web technology such that the appearance and
functionality of the GUI regions may be easily created and
upgraded. More specifically, the present invention uses a
corresponding browser and an associated web page for implementing
each GUI region. In this manner, the appearance and functionality
of a GUI region is created within a web page using a high-level
user-friendly standardized language such as Hypertext markup
language (HTML). In addition, because the web page defining the
appearance and functionality of the GUI region is located within a
predetermined server, that web page can be created or changed on
that predetermined server in order to create or upgrade the
appearance or functionality of the GUI region for all users.
[0011] With the present invention, the size and location of each of
at least one GUI region on a GUI display is defined within a host
application. In addition, the host application instantiates a
corresponding browser that points to an associated web page
defining the functionality and/or the appearance for each GUI
region. Furthermore, the host application exposes a corresponding
host application object to the corresponding browser for the
functionality of each GUI region. The corresponding browser for a
GUI region determines a respective appropriate time for the
functionality of that GUI region with an event handler. The
functionality for that GUI region is executed at that respective
appropriate time.
[0012] The present invention can be used to particular advantage
for implementing toolbars within a host application. In that case,
each GUI region, that is thus implemented with web technology, is
part of the toolbar provided by the host application. In addition,
the present invention can be used to permit a user to define GUI
parameters such as the location and size of each GUI region placed
by the host application on the GUI display. The user may further
specify the web page corresponding to each GUI region in building a
GUI display.
[0013] In another aspect of the present invention, a web page may
include an image tag for defining the appearance of the
corresponding GUI region. Each web page may also include a
hyperlink to at least one other web page and may include a Java
applet and/or active controls that perform the functionality of the
corresponding GUI region. Each web page may be written in HTML with
each browser being HTML compatible. In a further aspect of the
present invention, the web page for each GUI region may be located
on a predetermined server accessible via the Internet. In this
manner, functions associated with each GUI region can be created,
modified, and stored on different computer systems.
[0014] These and other features and advantages of the present
invention will be better understood by considering the following
detailed description of the invention which is presented with the
attached drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0021] Referring to FIG. 2, a host application 102 may be any
application running on a host terminal having a graphical user
interface (GUI) display 104. For example, the host application may
be a word processor application. The host application 102 may be
written in C++, VISUAL BASIC.RTM., or any other conventional
programming language. Typically, the host application code must be
compiled and linked into an executable form which can be
distributed on computer readable media such as disk or CD-ROM.
[0022] The host application 102 creates GUI components on the GUI
display 104. Such GUI components have identifying appearances on
the GUI display 104 and provide different functions to the
application. Although it should be appreciated by any one of
ordinary skill in the art that the present invention can be applied
to any such GUI components, the present invention will be described
for the example of a toolbar GUI component within a word processor
application. In this example, the toolbar GUI component consists of
GUI regions 112, 114, 116, 118, and 120 on the GUI display 104.
[0023] Referring to FIG. 2, a toolbar 106 comprises a predetermined
number of GUI regions with each GUI region having a corresponding
functionality and an identifying appearance on the GUI display 104.
For the example of a word processor application, the toolbar
includes a first GUI region 112 for "selecting a text font", a
second GUI region 114 for "saving a word processing file", a third
GUI region 116 for "cutting text", a fourth GUI region 118 for
"spell-checking", and a fifth GUI region 120 for "copying text". A
GUI region may also be provided for a help function (not
shown).
[0024] Although the GUI regions of FIG. 2 have the appearance with
only the text "FONT", "SAVE", "CUT", "SPELL CHECK", and "COPY", the
identifying appearance for each GUI region can also include other
forms for identification of the GUI region's corresponding
functionality. For example, a picture of scissors can be shown
within the third GUI region 116 for "cutting text", or a picture of
a diskette can be shown within the second GUI region 114 for
"saving a word processing file".
[0025] In contrast to the prior art toolbar, the implementation of
each GUI region on the toolbar 106 of FIG. 2 according to the
present invention is substantially independent of the host
application 102. In the present invention, the host application 102
includes an improved GUI component module 122 and a browser
duplicator 124. The improved GUI component module 122 defines a
toolbar having a predetermined number of GUI regions, including a
respective size and a respective location of each GUI region on the
GUI display 104.
[0026] This improved GUI component module 122 also instructs the
browser duplicator 124 to instantiate a corresponding browser for
each GUI region of the toolbar by calling a browser object model
via an API (Application Programming Interface) within an operating
system 142 as is known to one of ordinary skill in the art of
computer systems. Each browser may be any of the various
commercially available browsers such as Microsoft's Internet
Explorer or Netscape's Navigator.
[0027] In the example illustration of FIG. 2, the improved GUI
component module 122 defines the toolbar 106 having the five GUI
regions 112, 114, 116, 118, and 120 to be located toward the top of
the display 104 and to have a respective size on the display 104.
With the instantiation process, an executable code for each
corresponding browser is created by the host application 102 for
each GUI region. Thus, a first browser 132 is instantiated for the
first GUI region 112, a second browser 134 is instantiated for the
second GUI region 114, a third browser 136 is instantiated for the
third GUI region 116, a fourth browser 138 is instantiated for the
fourth GUI region 118, and a fifth browser 140 is instantiated for
the fifth GUI region 120. Each of these browsers upon instantiation
has a corresponding code which executes on the operating system 142
on a host terminal running the host application 102.
[0028] Each browser retrieves and executes the code within an
associated web page. The code within a web page is written in a
standardized language for the Internet. For example, the code
within a web page may be written in HTML, and the browsers may be
HTML compatible. In the example illustration of FIG. 2, a first web
page 152 corresponds to the first browser 132, a second web page
154 corresponds to the second browser 134, a third web page 156
corresponds to the third browser 136, a fourth web page 158
corresponds to the fourth browser 138, and a fifth web page 160
corresponds to the fifth browser 140.
[0029] In this manner, each GUI region of the toolbar is associated
with a browser which retrieves and executes a web page for that GUI
region. The contents of the web page define a corresponding
functionality and/or an identifying appearance of a GUI region on
the GUI display 104 when the corresponding browser executes the
associated web page. For example, a web page of a GUI region may
include image tags that define the identifying appearance of that
GUI region. In addition, the associated web page may include Java
applets that when executed carry out the functionality of that GUI
region when that GUI region is interacted with. Furthermore, the
associated web page may include active ACTIVEX.RTM. controls, as is
known to one of ordinary skill in the art of web page design, for
performing the corresponding functionality of a GUI region.
[0030] Each of the corresponding browsers includes one or more
event handlers, as is known to one of ordinary skill in the art of
web browser design, for determining a respective appropriate time
for performing the corresponding functionality for that GUI
region.
[0031] For example, referring to FIG. 2, the first browser 132
includes an event handler that provides the functionality of
changing text font when a user clicks on a selected font in the
pull-down font menu provided in the first GUI region 112. Other
example event handlers, such as automated timers, as is known to
one of ordinary skill in the art of computer systems design, may be
used within the browsers 132, 134, 136, 138, and 140. Such event
handlers determine a respective appropriate time for performing the
corresponding functionality of a GUI region.
[0032] The associated web page for a GUI region may also define the
corresponding functionality for that GUI region. The associated web
page defines one or both of the corresponding function and the
identifying appearance of a GUI region.
[0033] In addition, the corresponding browser may also bind to a
host application object model (or to an object model within any
other application program) for further carrying out the
functionality of a GUI region. Referring to FIG. 3, a host
application function interface 204 within the host application 102
exposes from the host application a corresponding host application
object model to each of the browsers 132, 134, 136, 138, and 140
using COM (Component Object Model) technology as is known to one of
ordinary skill in the art of software design.
[0034] Such communications between the browsers and the host
application provides host application functionality to GUI regions.
For example, if a GUI region were a "PRINT" region button, the
corresponding browser for that GUI region communicates with the
host application function interface 204 to bind to a "PRINT" object
model within the host application 102 for carrying out the print
function. An example script within the corresponding browser for
binding to the "PRINT" object model of the host application is as
follows:
[0035] <script language=vbscript>
[0036] sub print_on_click
[0037] host.print( )
[0038] end sub
[0039] <.backslash.script>
[0040] This code within a browser includes an event handler
"print_on_click" which determines that a file should be printed at
an appropriate time such as when the user clicks on the "PRINT" GUI
region button. Upon such an event, the host application object
model "host.print( )" is called via the host application function
interface 204 as illustrated in FIG. 3.
[0041] FIG. 3 shows an example of communications between the
corresponding browsers 132, 134, 136, 138, and 140 and the host
application 102. Alternatively, the corresponding browser for a GUI
region may not communicate with the host application. In that case,
the functionality of that GUI region may be determined solely by
the associated web page for that GUI region.
[0042] The web page corresponding to any GUI region may be located
within the host terminal running the executable code of the host
application. Alternatively, the web page may be located within a
web page server that is remotely located from the host terminal.
The browser corresponding to that web page can retrieve that web
page via the Internet. Referring to FIG. 4, a host terminal 302
running the executable code of the host application and the browser
for each GUI region of the tool bar is located remotely from a web
page server 304 on which the web page is located. The web page that
corresponds to one of the GUI regions of the toolbar may be
retrieved from any client server network via the Internet 306.
[0043] Referring to FIG. 5, the steps of operation of the present
invention for generating a toolbar within a host application is
summarized with a flowchart. The host application having the
toolbar begins execution at step 402. Referring to FIGS. 2 and 5,
the host application 102 defines a toolbar by specifying the
location and size of a predetermined number of GUI regions (at
least one GUI region) on a GUI display at step 404. The host
application also instantiates a corresponding browser that points
to an associated web page for each GUI region of the toolbar at
step 406.
[0044] Each web page when executed by the corresponding browser
determines one or both of a corresponding function and an
identifying appearance on the GUI display for a GUI region of the
toolbar. Thus, for example, one web page may display a picture of
scissors while another web page may display a hyperlink labeled
"HELP."
[0045] Each browser includes event handlers for determining an
appropriate time for performing the functionality of each GUI
region, and the functionality is performed at the respective
appropriate time for each GUI region at step 408. The functionality
of a GUI region may be defined by the associated web page for that
GUI region and/or by a host application object model as described
herein. The functionality of the GUI regions is provided by the
presence of the GUI region on the GUI display until the user exits
the host application at step 410. When the user exits the host
application, the browsers that were instantiated by the host
application are torn down by the host application during
termination of the host application at step 412. During the tear
down process, any executable code associated with the browsers is
deleted.
[0046] In this manner, each GUI region of the toolbar has a
particular appearance, content, and functionality which is
determined by an associated web page. This web page which is
created using a standardized language for the Internet is
independent of the host application having the toolbar. In contrast
to typical programming languages such as C++ used for coding the
host application, the web page is written in a user-friendly
high-level standardized language such as HTML which is more widely
known. Thus, the appearance, content, and functionality of the
toolbar GUI regions of the present invention may be created in an
easier and more standardized manner.
[0047] In addition, because appearance, content, and functionality
of a toolbar GUI region resides within a web page, such attributes
of the toolbar GUI region may be easily modified for an upgrade.
Only the web page of a corresponding upgraded GUI region is changed
using the user-friendly high-level standardized language of the web
page.
[0048] Furthermore, since the web page is modified, the code of the
host application need not be recompiled for any upgrades to the
toolbar of the present invention. With such an easy means for
modifying the appearance, content, and functionality of the toolbar
GUI regions, the GUI regions may be dynamic with an administrator
updating the associated web page of the corresponding GUI region
periodically.
[0049] Furthermore, the use of web technology for implementing the
toolbar GUI regions allows for more flexibility in the creation of
toolbars and other GUI components. With the browser being an
instance of Internet Explorer or Netscape Navigator, for example,
the functionality for any GUI region of the toolbar is not limited
to the functionality available on the host terminal. The associated
web page that defines a corresponding GUI region may be located
anywhere on the world wide web. Moreover, the associated web page
for a GUI region can further include hyperlinks to any other web
page on the world wide web. For the example of the word processor
application, the "spell check" GUI region may correspond to an
associated web page located on a remote web page server that may
provide one of the most comprehensive and sophisticated spell
checkers available on the world wide web.
[0050] The foregoing is by way of example only. For example, the
number of GUI regions on the toolbar of the present invention may
vary. In addition, a web page of a GUI region on the toolbar may
hyperlink to any number of other web pages via a hyperlinked chain
of web pages. Moreover, an associated web page for a GUI region may
define a plurality of subregions within that GUI region. Referring
to FIG. 2 for example, the toolbar 106 may be created using one
browser executing an associated web page that creates the GUI
regions 112, 114, 116, 118, and 120 as subregions within the
toolbar GUI region 106. Thus, generally, the toolbar within a host
application may be created using any number of browsers and any
number of web pages. In addition, the GUI display may be any
graphical user interface as is known to one of ordinary skill in
the art, aside from just the example of a computer screen.
[0051] More importantly, the present invention is not limited to
implementation of only toolbars within a word processor
application. The present invention may be generalized to the use of
web technology for implementing any GUI components comprised of GUI
regions on a GUI display. Referring to FIG. 6, the present
invention may be used for another type of application 502 that
hosts any GUI components on a GUI display 504 when the GUI
components are used with the application 502. Each GUI region of a
GUI component has a respective size and location on the GUI
display. For the example illustration of FIG. 6, a first GUI
component 506 provides a "calculator" function. A second GUI
component 508 provides a "password entry" function, and a third GUI
component 510 provides a "mailbox access" function. Each GUI
component provides a corresponding functionality and has an
identifying appearance on the GUI display.
[0052] The operation of the present invention as illustrated in
FIG. 6 is similar to that for creating the GUI regions of the
toolbar with each toolbar GUI region being similar to a GUI
component. Thus, an improved GUI component module 512 defines the
size and location of each GUI component on the GUI display 504. In
an alternative embodiment of the present invention, a user can
input GUI component parameters via a user input 514 to determine
the respective size and location of each GUI component on the GUI
display. Thus, the user can control the placement of the GUI
components on the GUI display.
[0053] The improved GUI component module 512 instructs a browser
duplicator 516 to instantiate a corresponding browser for each GUI
component. Thus a first browser 522 is instantiated for the first
GUI component 506, a second browser 524 is instantiated for the
second GUI component 508, and a third browser 526 is instantiated
for the third GUI component 510. These browsers execute on the
operating system 528 of the host application 502. Each browser
retrieves and executes an associated web page corresponding to each
GUI component. Thus, the first browser 522 executes a first web
page 532, the second browser 524 executes a second web page 534,
and the third browser 526 executes a third web page 536.
[0054] Each web page upon execution by the corresponding browser
defines the functionality and appearance of a GUI component on the
GUI display. The corresponding browser for each of the GUI
components determines an appropriate time for performing the
corresponding functionality of each GUI component. The present
invention can be used to particular advantage when the user can
select the associated web page for each GUI component in building
the components of the graphical user interface. Additionally, the
corresponding browser for any GUI component may bind to a host
object of a host application to provide host application
functionality via that GUI component.
[0055] In this manner, the present invention for building GUI
components as illustrated in FIG. 6 has similar operations and
advantages as already mentioned for the implementation of the
toolbar GUI regions. The invention is limited only as defined in
the following claims and equivalents thereof.
