Abstract

A method for maximizing the amount of screen display real estate without sacrificing the user'"'"'s ability to pan graphic and other data is disclosed which has application for use in computer controlled display systems. The CPU is capable of accessing and executing a computer program which includes a first event loop handler. The first event loop handler includes events, each which are selectively paired with a different set of screen coordinates, said set of screen coordinates comprising a first hot spot file. A user moves a pointer around on the screen display by using a pointer control device. The position of the pointer is monitored by the first event loop handler. The first event loop handler determines whether the position of the pointer corresponds to a set of screen coordinates in the first hot spot file which, in turn, corresponds to an event, most preferably, the display of a horizontal, vertical or diagonal scrollbar. The CPU executes the first event loop handler thereby causing a horizontal, vertical or diagonal scrollbar, most preferably, to appear on the screen display, but only when the position of the pointer corresponds to a set of screen coordinates in the main event table paired with a pre-selected event, again, most preferably the scrollbar displaying event which launches a panning means such as a horizontal, vertical or diagonal scrollbar. Then and only then is the screen display encumbered by the presence of scrollbars. Accordingly, it is not necessary to press a mouse button to initiate an event.

Claims

1. In a computer controlled display system comprising a display device responsive to a central processing unit (CPU) for displaying data, a method of maximizing display real estate on a display screen of said display device comprising the steps of:

said CPU retrieving and displaying said data on said display screen;

a user moving a pointer over at least a portion of said data on said display screen using a pointer control device coupled to said CPU;

said CPU monitoring a coordinate position of said pointer as said user moves said pointer over said data on said display screen;

said CPU determining whether the coordinate position of said pointer on said display corresponds to a predetermined area on said display screen and, if so, automatically activating a previously hidden display event on said display screen without any event selection by said user, whereby said user may use said pointer to interact with said display event, once activated, so long as said CPU determines that said pointer remains located over said predetermined area on said display screen; and

automatically deactivating said display event when said pointer is removed from said predetermined area on said display screen without any event selection by said user.

2. A method as in claim 1, wherein said predetermined area is a display "hot spot" on said display screen.

3. A method as in claim 1, wherein said predetermined area is a display icon on said display screen.

4. A method as in claim 1, wherein said previously hidden display event is a scrollbar display event which displays a scrollbar event which scrolls said data on said display screen in response to user selection using said pointer control device.

5. A method as in claim 4, comprising the further steps of:

said user positioning said pointer over a functional portion of said scrollbar event indicating a direction of scrolling of said data desired by said user; and

said user selecting said direction of scrolling of said data by said scrollbar event by depressing a select button on said pointer control device when said pointer is positioned over said functional portion of said scrollbar event.

6. A method as in claim 4, comprising the further step of modifying properties of at least one of said scrollbar displaying event and said scrollbar event.

7. A method as in claim 6, wherein the properties of said scrollbar displaying event include at least one of:

the presence of a time delay before the activation of said scrollbar event, a duration of said time delay, activation or deactivation of a display icon to indicate the launch of said scrollbar event, a type of icon used as an indicator of the launch of said scrollbar event, and a manner in which said scrollbar event is activated by the user.

8. A method as in claim 6, wherein the properties of said scrollbar event include at least one of:

type of scrollbar, screen position of said scrollbar, size, shape, and color of said scrollbar, and whether said scrollbar is visible or invisible.

9. A computer controlled display system comprising:

a display device having a display screen;

a pointer control device which permits a user to move a pointer over at least a portion of said data on said display screen; and

a central processing unit (CPU) which processes display software which retrieves and displays data on said display screen, monitoring software which monitors a coordinate position of said pointer on said display screen as said user moves said pointer over said data on said display screen, and event handler software including a main event table including a display event which is paired with a predetermined area on said display screen, said event handler software determining whether the coordinate position of said pointer on said display determined by said monitoring software corresponds to said predetermined area on said display screen and, if so, automatically activating said display event paired with said predetermined area without any event selection by said user, whereby said user may use said pointer to interact with said display event, once activated, so long as said event handler software determines that said pointer remains located over said predetermined area on said display screen, said event handler software further automatically deactivating said display event when said pointer is removed from said predetermined area on said display screen without any event selection by said user.

10. A system as in claim 9, wherein said predetermined area is a display "hot spot" on said display screen.

11. A system as in claim 9, wherein said predetermined area is a display icon on said display screen.

12. A system as in claim 9, wherein said display event is a scrollbar display event which displays a scrollbar event which permits the user to scroll said data on said display screen in response to user selection using said pointer control device.

13. A system as in claim 12, wherein said scrollbar event includes a scrollbar activation event handler including a scrollbar activation event table which, in turn, includes a further scrollbar display event which is paired with a scrolling device indicating a direction of scrolling of said data desired by said user, said scrolling device scrolling through said data in response to user depression of a select button on said pointer control device when said pointer is positioned over a functional portion of said scrolling device.

14. A system as in claim 13, wherein said scrolling device comprises a vertical scrollbar.

15. A system as in claim 13, wherein said scrolling device comprises a horizontal scrollbar.

16. A system as in claim 13, wherein said scrolling device comprises a diagonal scrollbar.

17. A system as in claim 13, wherein said scrolling device comprises a dial.

18. A system as in claim 13, wherein said scrolling device comprises a gauge.

19. A system as in claim 13, wherein said scrolling device comprises an icon.

20. A system as in claim 13, wherein said scrollbar activation event handler further includes a modifying event handler which modifies properties of at least one of said scrollbar displaying event and said scrollbar event.

21. A system as in claim 20, wherein the properties of said scrollbar displaying event include at least one of:

the presence of a time delay before the activation of said scrollbar event, a duration of said time delay, activation or deactivation of a display icon to indicate the launch of said scrollbar event, a type of icon used as an indicator of the launch of said scrollbar event, and a manner in which said scrollbar event is activated by the user.

22. A system as in claim 20, wherein the properties of said scrollbar event include at least one of:

type of scrollbar, screen position of said scrollbar, size, shape, and color of said scrollbar, and whether said scrollbar is visible or invisible.
