Abstract

A graphical user interface (GUI) element for simulating scrolling a display pane that displays a visible set of data records. A set of data records are selected from a data store and the visible set of data records include data records from the selected set of data records. The GUI element includes a scroll bar control element corresponding to the display pane. The scroll bar control element is operable to update the visible set of data records in response to a scroll bar control event. In the GUI element, only a subset of the selected set of data records are received by the user interface element.

Claims

1. A user interface element for simulating scrolling comprising:

a display pane operable to display a visible set of data records, the visible set of data records including data records from a selected set of data records from a data store; and

a scroll bar control element corresponding to the display pane, the scroll bar control element operable to update the visible set of data records in response to a scroll bar control event,

wherein a subset of the selected set of data records are received by the user interface element.

2. The user interface element of claim 1 wherein the subset of the selected set of data records include only data records displayed in the display pane.

3. The user interface element of claim 1 wherein the scroll bar control element includes a slider button.

4. The user interface element of claim 3 wherein the size of the slider button is determined by the number of data records in the selected set of data records.

5. The user interface element of claim 4 wherein the number of data records is determined in logarithmic time.

6. The user interface element of claim 4 wherein the number of data records is determined using an augmented traversable tree structure.

7. The user interface element of claim 6 wherein each node of the traversable tree structure is augmented with a counter that may be used to determine the number of data records.

8. The user interface element of claim 1 wherein the selected set of data records is determined by executing a data store query.

9. A data query tool comprising:

a data store operable to store data records;

a data query software application operable to query the data store to identify data records satisfying a query statement; and

a user interface for displaying identified data records, the user interface including;

a display pane operable to display a visible set of data records, the visible set of data records including a subset of the identified data records; and

a scroll bar control element corresponding to the display pane, the scroll bar control element operable to update the visible set of data records in response to a scroll bar control event,

wherein a subset of the identified data records are received by the user interface.

10. The data query tool of claim 9 wherein the subset of the identified data records include only data records displayed in the display pane.

11. The data query tool of claim 9 wherein the scroll bar control element includes a slider button.

12. The data query tool of claim 11 wherein the size of the slider button is determined by the number of the identified data records.

13. The data query tool of claim 12 wherein the number of identified data records is determined in logarithmic time.

14. The data query tool of claim 12 wherein the number of identified data records is determined using an augmented traversable tree structure.

15. The data query tool of claim 14 wherein each node of the traversable tree structure is augmented with a counter usable to determine the number of identified data records.

16. The data query tool of claim 9 wherein the number of identified data records is determined by querying the data store.

17. A method for simulating scrolling in a graphical user interface, the method comprising:

providing a list pane operable to display a visible set of data records in a graphical user interface;

providing a scroll bar control element corresponding to the list pane, the scroll bar control element operable to update the visible set of data records in response to a scroll bar control event;

querying a data store to identify a set of data records satisfying a query statement;

receiving a subset of the identified data records, the subset including the visible set of data records; and

displaying the visible set of data records.

18. The method of claim 17 further comprising

waiting for a graphical user interface event;

and

upon receiving a graphical user interface event, updating the visible set of data records in response to the received graphical user interface event.

19. The method of claim 17 wherein the subset of the identified data records include only data records displayed in the display pane.

20. The method of claim 17 further comprising receiving the number of identified data records.

21. The method of claim 20 wherein the number of identified data records is determined in logarithmic time.

22. The method of claim 20 wherein the number of identified data records is determined using an augmented traversable tree structure.
