Abstract

Menu item selection is performed in a personal computer system through the use of a mouse device which has means to allow the user to call up onto the display a header block which performs the function of the menu bar and to erase the header block from the screen when menu operations are not required. Multiple menu items can be selected during the same menu session by using a pair of mouse buttons to generate a sequence of selection commands which are utilized by unique system software to accumulate plural item selections without terminating the menu operation.

Claims

1. In a computer system for displaying operator selectable menu items and a cursor image, said system having memory means and an operator controllable cursor positioning device with selection signal generating means, a method comprising the steps of:

storing in a first section of said memory means header data representing a menu header block and menu data representing a plurality of menu blocks;

transferring to a second section of said memory means in response to generation of a first selection signal a header bit pattern derived from said header data, said bit pattern representing a visual depiction of said menu header block; and

displaying a menu header block image based on said header bit pattern stored in said second memory section.

2. The method of claim 1 comprising the further steps of:

positioning said cursor image in a selected location within said displayed header block;

transferring to said second memory section in response to said positioning a menu bit pattern derived from said menu data, said menu bit pattern representing a visual depiction of a selected one of said menu blocks, the selected menu block corresponding to the location of said cursor image within said header block and containing a plurality of selectable menu items; and

displaying a menu block image based on said menu bit pattern.

3. The method of claim 2 wherein said displayed menu block image is positioned below said header block image in proximity to the location of said cursor image.

4. The method of claim 2 comprising the further steps of:

positioning said cursor image within said displayed menu block image to a location designating a selected menu item; and

storing in said memory means in response to said last-mentioned positioning a control word representing said selected menu item.

5. The method of claim 4 comprising the further steps of:

generating a second selection signal; and

compiling in response to said second selection signal a menu item selection message containing said control word.

6. The method of claim 5 in which said selection signal generating means comprises an operator controllable selection button which is depressed to generate said first selection signal and which is released to generate said second selection signal.

7. The method of claim 4 comprising the further steps of:

storing in said first memory section submenu data representing a plurality of submenu blocks;

transferring to said second memory section in response to said last-mentioned positioning a submenu bit pattern derived from said submenu data, said bit pattern representing a visual depiction of a submenu block, said submenu block corresponding to said selected menu item and containing a plurality of selectable submenu items; and

displaying a submenu block image based on said submenu bit pattern stored in said second memory section.

8. The method of claim 7 wherein said displayed submenu block image is positioned adjacent to said menu block image in proximity to the location of said cursor image.

9. The method of claim 7 comprising the further steps of:

positioning said cursor image within said displayed submenu block to a location designating a selected submenu item; and

storing in said memory means in response to said last-mentioned positioning a control word representing said selected submenu item.

10. The method of claim 9 comprising the further steps of:

generating a second selection signal; and

compiling in response to said second selection signal a menu item selection message containing said menu item and submenu item control words.

11. The method of claim 10 wherein said menu item control word is coded to indicate to said system that a submenu control word must be present in said menu item selection message to convey valid selection data.

12. In a computer system for displaying operator selectable menu items and a cursor image, said system having memory means and an operator controllable cursor positioning device with selection signal generating means, a method comprising the steps of:

displaying a menu block containing areas designating a plurality of selectable menu items;

storing in a first section of said memory means a control word representing the menu block area in which said cursor image is positioned, said stored control word being changed when said cursor image is moved to reflect the menu block area in which said cursor image is currently positioned; and

compiling a selection message in response to generation of a selection signal, said message including the control word in said first memory section at the time said selection signal is generated.

14. The method of claim 12 comprising the further step of storing in said first memory section a control word having a null value when said cursor image is positioned outside the boundaries of said menu block, whereupon compilation of said selection message to include said null value control word indicates the absence of a menu item selection.

13. In a computer system for displaying operator selectable menu items and a cursor image, said system having memory means and an operator controllable cursor positioning device with selection signal generating means for generating a plurality of first and a second selection signal a method comprising the steps of:

displaying a menu block containing areas designating a plurality of selectable menu items;

storing in a first section of said memory means a control word representing the menu block area in which said cursor image is positioned, said stored control word being changed when said cursor image is moved to reflect the menu block area in which said cursor image is currently positioned;

transferring to a second section of said memory means from said first memory section a plurality of different control words, each of said plural control words being transferred in response to generation of a different one of said first selection signals; and

compiling a selection message in response to generation of said second selection signal, said message including said plural control words present in said second memory section at the time said second selection signal is generated.

15. The method of claim 13 in which said selection signal generating means comprises first and second operator controllable selection buttons, said plurality of first selection signals being generated by depressing said second button a plurality of times while said first button is held in the depressed position and said second selection signal being generated by releasing said first button.

16. The method of claim 15 comprising the further step of generating a first selection signal in response to changing of the control word stored in said first memory section at a time when both said selection buttons are in the depressed position.
