Abstract

The present invention provides a method and system for providing improved controls in a graphical user interface. One feature of the present invention provides a control that enables a user to assign multiple values to the control. This multi-value field control includes an extension to known controls that allows the user to enter more than one value into the control. After a value has been entered into the multi-value field control, the user can modify or delete the value. Another feature of the present invention provides a control that enables a user to efficiently specify multiple sort criteria for the control. This sort order control lists all of the possible sort criteria together with a selection indicator next to each sort criteria. When the user selects a sort criteria, the sort order control indicates the selection of the sort criteria in the selection indicator and places a numeric character representing the order in which the sort criteria was selected next to the sort criteria. Another feature of the present invention provides a control that enables a user to manipulate lists in the control. The list operations that can be performed using the list control include: (1) swapping columns, (2) freezing and unfreezing columns, (3) hiding and showing columns, and (4) finding text in columns.

Claims

1. A method for efficiently specifying multiple sort criteria for a graphical user interface control, the method comprising the steps of:

displaying a list of all possible sort criteria in a sort order control;

displaying a selection indicator next to each sort criteria in the sort order control;

entering a selection of a sort criteria;

indicating the selection of the sort criteria in the selection indicator next to the sort criteria; and

placing a numeric character representing the order in which the sort criteria was selected next to the sort criteria.

2. The method of claim 1, further comprising the step of:

maintaining information regarding the order in which the sort criteria are selected.

3. The method of claim 2, further comprising the step of:

after each sort criteria is selected, placing the next higher numeric character next to the sort criteria.

4. The method of claim 2, further comprising the step of:

de-selecting a sort criteria that has been selected in the sort order control.

5. The method of claim 4, wherein the step of de-selecting a sort criteria includes the steps of:

entering a selection of a sort criteria to be de-selected;

indicating the de-selection of the sort criteria in the selection indicator next to the sort criteria; and

removing the numeric character next to the sort criteria.

6. The method of claim 5, wherein the step of de-selecting a sort criteria further includes the step of:

adjusting the numeric characters next to the remaining selected sort criteria.

7. The method of claim 1, wherein the selection indicator includes a check box.

8. The method of claim 7, wherein the step of indicating the selection of the sort criteria in the selection indicator includes the step of placing an "X" in the check box next to the sort criteria.

9. The method of claim 5, wherein the selection indicator includes a check box.

10. The method of claim 9, wherein the step of indicating the de-selection of the sort criteria in the selection indicator includes the step of removing an "X" in the check box next to the sort criteria.

11. A system for efficiently specifying multiple sort criteria for a graphical user interface control, the system comprising:

a central processing unit for controlling the system;

a storage connected to the central processing unit; and

a graphical user interface stored in the storage for execution by the central processing unit, the graphical user interface including a sort order control for;

displaying a list of all possible sort criteria in the sort order control,

displaying a selection indicator next to each sort criteria in the sort order control,

entering a selection of a sort criteria,

indicating the selection of the sort criteria in the selection indicator next to the sort criteria, and

placing a numeric character representing the order in which the sort criteria was selected next to the sort criteria.

12. A computer program product for use in a computer system, the computer program product comprising:

a computer usable medium having computer readable program code means embodied in the medium for efficiently specifying multiple sort criteria for a graphical user interface control, the computer readable program code means including;

computer readable program code means for displaying a list of all possible sort criteria in a sort order control;

computer readable program code means for displaying a selection indicator next to each sort criteria in the sort order control;

computer readable program code means for entering a selection of a sort criteria;

computer readable program code means for indicating the selection of the sort criteria in the selection indicator next to the sort criteria; and

computer readable program code means for placing a numeric character representing the order in which the sort criteria was selected next to the sort criteria.
