Abstract

A method of indicating expanded states and collapsed states of lower level expander/collapser items in a higher level visual control of a user interface display. The method includes providing, in the higher level visual control, a lower level expander/collapser indicator area; displaying a first display in the expander/collapser indicator area when all the lower level expander/collapser items are in a first state; displaying a second different display in the expander/collapser indicator area when all of the lower level expander/collapser items are in a second different state; and displaying a third different display in the expander/collapser indicator area when a first one of the lower level expander/collapser items is in the first state and a second one of the lower level expander/collapser items is not in the first state.

Claims

1. A program storage device readable by a machine, tangibly embodied in a program of instructions executable by the machine to perform operations to indicate expanded states and collapsed states, in a higher level visual control, of lower level expander/collapser items in a user interface display, the operations comprising:

providing a lower level expander/collapser indicator area in the higher level visual control;

displaying a first display in the expander/collapser indicator area when all the lower level expander/collapser items are in a collapsed state;

displaying a second different display in the expander/collapser indicator area when all of the lower level expander/collapser items are in an expanded state; and

displaying a third different display in the expander/collapser indicator area when at least one of the lower level expander/collapser items is in the collapsed state and at least another one of the lower level expander/collapser items is in the expanded state.

2. The program storage device as in claim 1 wherein, during display of the third display, the method comprises displaying at least two different mixed state action buttons in the lower level expander/collapser indicator area of the higher level visual control.

3. The program storage device as in claim 1 further comprising maintaining the lower level expander/collapser indicator area as a substantially same size when displaying the first, second and third displays in the indicator area.

4. A method of indicating expanded states and collapsed states of lower level expander/collapser items in a higher level visual control of a user interface display, the method comprising:

providing, in the higher level visual control, a lower level expander/collapser indicator area;

displaying a first display in the expander/collapser indicator area when all the lower level expander/collapser items are in a first state;

displaying a second different display in the expander/collapser indicator area when all of the lower level expander/collapser items are in a second different state; and

displaying a third different display in the expander/collapser indicator area when a first one of the lower level expander/collapser items is in the first state and a second one of the lower level expander/collapser items is not in the first state.

5. The method as in claim 4 wherein displaying the third different display comprises displaying at least two different mixed state action buttons in the lower level expander/collapser indicator area of the higher level visual control.

6. The method as in claim 4 further comprising maintaining the lower level expander/collapser indicator area as a substantially same size when displaying the first, second and third displays in the indicator area.

7. The method as in claim 6 wherein displaying the third different display comprises providing two arrow shaped buttons in the indicator area pointing in different directions.

8. The method as in claim 6 wherein displaying the third different display comprises providing a plus (+) shaped button and a minus (−

) shaped button in the indicator area.

9. The method as in claim 4 wherein displaying the third different display occurs when only a first lower level immediately beyond the higher level visual control contains both items in the first state and items not in the first state, and does not occur when a second deeper lower level beyond the first lower level contains both items in the first state and items not in the first state.

10. The method as in claim 4 wherein displaying the third different display occurs when a first lower level immediately beyond the higher level visual control contains both items in the first state and items not in the first state, and when a second deeper lower level beyond the first lower level contains both items in the first state and items not in the first state.

11. A method of expanding expander/collapser items in a lower level of a user interface display comprising:

indicating expanded states and collapsed states of the expander/collapser items as in claim 4;

selecting a first action button in the third display to expand all the expander/collapser items in the lower level to the second state, wherein the second state comprises an expanded state.

12. A method of collapsing expander/collapser items in a lower level of a user interface display comprising:

indicating expanded states and collapsed states of the expander/collapser items as in claim 4;

selecting a second action button in the third display to collapse all the expander/collapser items in the lower level to the first state, wherein the first state comprises a collapsed state.

13. A method of expanding expander/collapser items in a lower level of a user interface display comprising:

indicating expanded states and collapsed states of the expander/collapser items as in claim 4;

allowing only one expander/collapser item in the lower level to be expanded at any one time when the expander/collapser item is directly expanded by selection of a user; and

expanding all the expander/collapser items in the lower level when an action button in the indicator area of the higher level visual control is selected by the user.

14. A user interface control system comprising:

a system for displaying a mixed state expander/collapser button area in a lower level expander/collapser indicator area of a higher level visual control when lower level expander/collapser items include at least one of the items being in an expanded state and at least another one of the items being in a collapsed state, wherein the button area comprises a first mixed state action button adapted to expand all the lower level expander/collapser items to the expanded state and a second mixed state action button adapted to collapse all the lower level expander/collapser items to the collapsed state; and

a system for changing display in the indicator area, wherein the system for changing is adapted to change a display of the mixed state expander/collapser button area in the indicator area into an expander button after the second mixed state action button is selected, and wherein the system for changing is adapted to change the mixed state expander/collapser button area into a collapser button after the first mixed state action button is selected.

15. The user interface control system as in claim 14 wherein the mixed state action buttons comprise arrow shaped buttons pointing in different directions.

16. The user interface control system as in claim 15 wherein the button area further comprises a diagonal arrow shaped symbol and the arrow shaped buttons are located at different sides of the diagonal arrow shaped symbol.

17. The user interface control system as in claim 15 wherein the mixed state action buttons comprise a plus (+) shaped indicator and a minus (−

) shaped indicator.

18. The user interface control system as in claim 14 wherein the mixed state action buttons comprise a general line (−

) shaped indicator and a general box (□

) shaped indicator.

19. The user interface control system as in claim 14 wherein the expander button, the collapser button and the mixed state button area are adapted to be displayed in a same size lower level expander/collapser indicator area of the higher level visual control.

20. The user interface control system as in claim 14 wherein the system for changing is adapted to change display of the expander button to the mixed state expander/collapser button area when one of the lower level expander/collapser items is expanded from a collapsed state to an at least partially expanded state.
