DETAILED DESCRIPTION
In the following description, for the purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the present invention. It will be evident to one skilled in the art, however, that the exemplary embodiments may be practiced without these specific details. In other instances, structures and device are shown in diagram form in order to facilitate description of the exemplary embodiments. Further, while the method and system is described primarily in the context of retail management systems for retail products and articles such as retail fashion articles, it should be understood that the method and system are applicable in other contexts, including management systems for service providers.
FIG. 1 illustrates a graphical user interface screen 100 for use with an automated management system for products and or services (e.g., retail fashion articles, etc.) and configured to facilitate switching among management system applications according to an exemplary embodiment. Screen 100 may include an area 102 for displaying a worklist 104, and an area 106 for displaying a group of one or more management system applications 108 associated with an item in worklist 104, such as applications 108a, 108b, and 108c shown in FIG. 1. Screen 100 also includes one or more user-actuated inputs (e.g., buttons, icons, etc.) 110 configured to facilitate switching among applications 108. It should be understood that while user-actuated inputs 110 are primarily illustrated and described herein as “buttons” (e.g., a symbol, icon, etc. displayed in screen area 102 and configured to appear as a virtual button that may be depressed), other types of user-actuated inputs displayed as part of a graphical user interface are contemplated as well.
In the illustrated embodiment, screen area 102 starts as an empty workset with no items displayed. A user of system 100 may select button 112 by executing a user input command (e.g., by using a mouse to point to and click on button 112) in order to display worklist 104. Worklist 104 may be, for example, a personalized default list of items associated with a particular user for a particular workbench. In the illustrated embodiment, worklist 104 is a hierarchical default worklist of grouped purchase order documents associated with a particular user of the management system for particular workbench for generating and managing purchase orders.
Once worklist 104 is displayed in screen area 102, the user may select one of the items in worklist 104 by executing a user input command (e.g., by using a mouse to point to and click on an item in worklist 104) in order to display the associated applications 108 in individual areas in screen area 106. For example, in the illustrated embodiment, selecting worklist item 114 causes at least applications 108a, 108b, and 108c to be displayed in individual areas in screen area 106. In addition to applications 108 that are displayed in screen area 106, there may be additional applications 108 that are not displayed in screen area 106 depending on, for example, the amount of area available in screen area 106. These applications may be accessed and viewed using buttons 110 as will be described below. Once applications 108 are displayed in screen area 106 for the selected worklist item, worklist 104 may be hidden from view by selecting button 118 to cause screen area 102 to disappear and screen area 106 to be enlarged to cover the screen area previously devoted to screen area 102 (as shown in FIGS. 2-24).
The associated applications may be software applications that are used to process data in the worklist item. For example, in the illustrated embodiment, applications 108 are software applications for processing purchase order list data in order to generate purchase orders. According to various other embodiments, other types of software applications may be used.
Screen 100 also includes a button 120 that may be selected by the user to display a list of applications 108 associated with the selected worklist item and available for display within screen area 106. FIG. 2 illustrates an exemplary screen 200 that may be used to display a list of applications 108 associated with the selected worklist item and available for display within screen area 106 once button 120 has been selected. For example, in the illustrated embodiment, selecting button 120 calls screen 200, which displays a list including applications 108a, 108b, 108c, 108d, and 108e. The list displayed in screen 200 represents the order in which applications 108 are displayed in screen area 106. For example, applications 108a, 108b, and 108c, are the first three applications displayed. Applications 108d and 108e are not displayed in screen area 106 due to the amount of area available in screen area 106, but are the next available applications 108 that may be displayed using buttons 110 as will be described below. The user may select a button 201 in order to close screen 200.
FIG. 3 illustrates an embodiment of graphical user interface screen 100 wherein three out of five applications 108 associated with the selected worklist item and available for display within screen area 106 are displayed in screen area 106, which has been enlarged to cover the screen area previously devoted to screen area 102. As shown in FIG. 3, applications 108a, 108b, and 108c are displayed in screen area 106. Applications 108d and 108e are not displayed. Using buttons 110, the user may move up or down the order of applications 108 that are available for display within screen area 106 in order to switch among the applications. In the illustrated embodiment, the user may use button 110a to move down the order of available applications 108 one application at a time until the desired application or applications 108 are displayed. The user may use button 110b to move down the order of available applications 108 directly to the last application 108 available for display in screen area 106 such that it is the only application displayed in screen area 106. The user may use button 110c to move up the order of available applications 108 one application at a time until the desired application or applications 108 are displayed. The user may use button 110d to move up the order of available applications 108 directly to the first application 108 available for display in screen area 106 such that it is the first application displayed in screen area 106.
According to an exemplary embodiment, when the first application in the order of available applications 108 is also the first application displayed in screen area 106, only buttons 110a and 110b are available such that the user may only move down in the order of available applications 108. For example, as shown in FIG. 3, application 108a is the first application displayed in screen area 106, and only buttons 110a and 110b are available to the user. Buttons 108c and 108d are displayed in a lighter shade to indicate that they are currently inactive. In this embodiment, when the first application in the order of available applications 108 is no longer the first application displayed in screen area 106, buttons 110a, 110b, 110c, and 110d are available such that the user may move up or down in the order of available applications 108 (as shown in FIG. 4). When the last application in the order of available applications 108 is also the only application displayed in screen area 106, only buttons 110c and 110d are available such that the user may only move up in the order of available applications 108 (as shown in FIG. 5)
FIG. 4 illustrates an embodiment of screen 100 wherein button 110a has been used to move down one application in the order of applications 108 so that applications 108b, 108c, and 108d are now displayed in order in screen area 106 instead of applications 108a, 108b, and 108c.

Similarly, FIG. 5 illustrates an embodiment of screen 100 wherein button 110a has been used four more times to move down the order of applications 108 one application at a time so that the last application, application 108e, is now displayed in screen area 106 instead of applications 108b, 108c, and 108d. As shown in FIG. 5, the last application in the order of available applications 108 is also the only application 108 displayed in screen area 106, and only buttons 110c and 110d are available such that the user may only move up in the order of available applications 108.
FIG. 6 illustrates an embodiment of screen 100 wherein button 110c has been used to move up one application in the order of applications 108 so that applications 108e and 108e are now displayed in screen area 106 instead of only application 108e as shown in FIG. 5. As shown in FIG. 6, the last application in the order of available applications 108 (i.e., application 108e) is no longer the only application 108 displayed in screen area 106, and buttons 110a, 110b, 110c, and 110d are now available such that the user may move up or down in the order of available applications 108.
FIG. 7 illustrates an embodiment of screen 100 wherein button 110c has been used four more times to move up the order of applications 108 one application at a time so that the first application 108a in the order of applications 108 is now displayed in screen area 106 instead of applications 108d and 108e. As shown in FIG. 7, the first application in the order of available applications 108 is also the first application 108 displayed in screen area 106, and only buttons 110a and 110b are available such that the user may only move down in the order of available applications 108.
FIG. 8 illustrates an embodiment of screen 100 wherein button 110b has been used to move down the order of available applications 108 directly to the last application 108 available for display in screen area 106. As shown in FIG. 8, application 108e is the only application displayed in screen area 106, instead of applications 108a, 108b, and 108c as shown in FIG. 7.
FIG. 9 illustrates an embodiment of screen 100 wherein button 110d has been used to move up the order of available applications 108 directly to the first application 108 available for display in screen area 106. As shown in FIG. 9, application 108a is the first application displayed in screen area 106 along with applications 108b and 108c, instead of only application 108e as shown in FIG. 8.
According to an exemplary embodiment, each of the applications 108 displayed in screen area 106 includes a button 122 as shown in FIG. 9 that may be selected by the user in order to display the application in a “full-screen” mode. FIG. 10 illustrates an embodiment of screen 100 wherein button 122 shown in FIG. 9 has been used to display application 108a in a full-screen mode. In the full-screen mode shown in FIG. 10, application 108a has been expanded to fill approximately the entire area of screen area 106, including the area previously devoted to applications 108b and 108c. 
While an application 108 is in full-screen mode, buttons 110 may be used to move up or down the order of available applications 108. FIG. 1 illustrates an embodiment of screen 100 wherein button 110a has been used to move down one application in the order of applications 108 so that applications 108b, 108c, and 108d are now displayed in order in screen area 106 instead of full-screen application 108a. As shown in FIG. 1, applications 108b, 108c, and 108d are not displayed in full-screen mode. FIG. 12 illustrates an embodiment of screen 100 wherein button 110c has been used to move up one application in the order of applications so that application 108a is again displayed in screen area 106 in full-screen mode. Selecting button 122 again switches application 108a from full-screen mode to the original size, such that applications 108b and 108c are again displayed in display area 106 as shown in FIG. 13.
FIG. 14 illustrates an embodiment of screen 100 wherein button 120 (shown in FIG. 13) and screen 200 are used to change the display order of applications 108 associated with the selected worklist item and available for display within screen area 106. Screen 200 includes a button 202 for each available application 108, as well as buttons 204 for moving a selected application 108 up or down in the order. In order to move an application 108 up or down in the order, the user selects the button 202 corresponding to the application to be moved and then uses one of buttons 204 to move the application up or down in the order. Button 204a moves the selected application 108 up one position in the display order. Button 204b moves the selected application down one position in the display order. Button 204c moves the selected application to the first position in the display order. Button 204d moves the application to the last position in the display order.
As shown in FIG. 14, to move application 108e from the last position to the first position in the display order, button 202e is selected, and then button 204c is selected. As shown in FIG. 15, application 108e is now listed in the first position of the display order, and applications 108a, 108b, 108c, and 108d have moved down one position in the display order. Similarly, to move application 108c from the fourth position in the display order to the second position in the display order, button 202d is selected and then button 204a is selected twice. As shown in FIG. 16, application 108c is now listed in the second position in the display order and applications 108a and 108b have moved down another position in the display order. To move application 108d from the last position in the display order to the third position in the display order, button 202e is selected and then button 202a is selected twice. As shown in FIG. 17, application 108d is now listed in the third position in the display order and applications 108a and 108b have moved down another position in the display order.
Selecting button 201 adopts the changes to the display order. For example, FIGS. 18-19 illustrate an embodiment of screen 100 wherein button 201 has been selected to implement the changes to the display order as described above with reference to FIGS. 14-17. As shown in FIG. 18, application 108e is now displayed as the first application in screen area 106, application 108c is now displayed as the second application in screen area 106, and application 108d is now displayed as the third application in screen area 106. As shown in FIG. 19, selecting button 110a twice to move down through the display order by two applications 108 reveals that applications 108a and 108b are now the fourth and fifth applications.
FIG. 20 illustrates an embodiment of screen 100 wherein button 120 (shown in FIG. 19) and screen 200 are used to select which of applications 108 associated with the selected worklist item and available for display within screen area 106 are to be displayed. Screen 200 includes a check box 206 for each available application 108. In order to select an application 108 to be removed from the list of available applications 108 to be displayed, the user deselects the checkbox next to the application 108. For example, as shown in FIG. 20, the checkboxes 206 corresponding to applications 108a and 108b have been deselected so that these applications will no longer be visible in screen area 106.
Selecting button 201 adopts the changes. For example, FIGS. 21-22 illustrate an embodiment of screen 100 wherein button 201 has been selected to implement the changes to the applications selected for display as described above with reference to FIG. 20. As shown in FIG. 21, application 108e is still displayed as the first application in screen area 106, application 108c is still displayed as the second application in screen area 106, and application 108d is still displayed as the third application in screen area 106. As shown in FIG. 22, selecting button 110a to move down through the display order by 108 reveals that applications 108a and 108b are no longer displayed.
FIG. 23 illustrates an embodiment of screen 100 wherein the sizes of the individual display areas for each individual application 108 may be changed. As shown in FIG. 23, a lower border 130 for each individual application may be moved up or down to decrease or increase the size of the individual screen area for each application 108 (e.g., by selecting and “dragging” the border up or down using a mouse). FIG. 24 illustrates an embodiment of screen 100 wherein the sizes of the individual display areas for each individual application 108 have been decreased by moving up the lower borders 130 for applications 108e, 108c, and 108d respectively.
