First Claim
1. A method of providing a display control mechanism for information in a handheld computer or tablet PC, comprising:
- displaying information of a webpage in a display area on a display in said data processing system, the displayed information comprising at least one interactive element and non-interactive element of said webpage;
displaying a cursor on said display, said cursor capable of being activated by an input device;
detecting activation of said cursor;
determining an activation position of said cursor, said activation position being the position of said cursor on said display at which said detected activation occurred, said activation position being determined in relation to the at least one interactive element and non-interactive element;
detecting movement of said cursor after being activated; and
in response to detecting said activation and movement, determining whether the display area on the display is to be scrolled by performing the following;
determining whether the portion of said webpage at the activation position contains an interactive element or non-interactive element of said webpage,if the portion of said webpage is determined to contain a non-interactive element of said webpage, scrolling the displayed information in tandem with said movement of said cursor in the display area, andif the portion of said webpage is determined to contain an interactive element of said webpage, making a further determination as to whether to activate the contained interactive element or perform scrolling of the display area based on a defined behavior for the contained interactive element.

Abstract
Aspects of the present invention provide a system and method for scrolling or dragging information on a display. A panning tool is provided that may scroll information, such as a web page, on a display in tandem with movement of a cursor. If interactive elements are present on the page or document, an interactive element may be activated as desired. Scrolling may be accomplished with the panning tool either on non-interactive elements or interactive elements that are not required to be activated. Furthermore, inertia of movement of the information on a display is optimized and autoscrolling is provided in which a page or document may be scrolled without dragging.

7. A system for providing a display control mechanism for information in a data processing system, comprising:
-
a display for displaying information in a display area and displaying a cursor, the displayed information comprising at least one interactive element and non-interactive element, said cursor capable of being activated by an input device; a processor for; detecting activation of said cursor; determining an activation position of said cursor, said activation position being the position of said cursor on said display at which said detected activation occurred, said activation position being determined in relation to the at least one interactive element and non- interactive element; in response to detecting said activation and movement, determining whether the display area on the display is to be scrolled based on a determination of whether the portion of the displayed information at the activation position contains an interactive element or non-interactive element, wherein the displayed information is scrolled in the display in tandem with moving said cursor in the display area if an element underlying said cursor when activated in the display area is determined to be a non-interactive element, and wherein if an element underlying said cursor when activated in the display area is determined to be an interactive element, a further determination is made as to whether to perform scrolling of the display area based on the underlying interactive element. - View Dependent Claims (8, 9, 10, 11, 12, 13, 22, 23, 24)

14. A computer-readable storage medium comprising executable code for causing a handheld computer or tablet PC to perform the steps of:
-
displaying information of a webpage in a display area on a display, the displayed information comprising at least one interactive element and non-interactive element of said webpage; displaying a cursor on said display, said cursor capable of being activated by an input device; detecting activation of said cursor and detecting the activation position of said cursor, the activation position being the position on the display at which said cursor was activated, said activation position being determined in relation to the at least one interactive element and non-interactive element; determining an activation position of said cursor, said activation position being the position of said cursor on said display in relation to the at least one interactive element and non-interactive element; detecting movement of said cursor after being activated; and in response to detecting said activation and movement, determining whether the display area on the display is to be scrolled by performing the following; determining whether the portion of said webpage at the activation position contains an interactive element or non-interactive element of said webpage, if the portion of said webpage is determined to contain a non-interactive element of said webpage, scrolling the displayed information in tandem with said movement of said cursor in the display area, and if the portion of said webpage is determined to contain an interactive element of said webpage, making a further determination as to whether to activate the contained interactive element or perform scrolling of the display area based on a defined behavior for the contained interactive element. - View Dependent Claims (15, 16, 17, 18, 19, 25, 26)
