Abstract

At least certain embodiments of the present disclosure include an environment with user interface software interacting with a software application to provide gesture operations for a display of a device. A method for operating through an application programming interface (API) in this environment includes transferring a scaling transform call. The gesture operations include performing a scaling transform such as a zoom in or zoom out in response to a user input having two or more input points. The gesture operations also include performing a rotation transform to rotate an image or view in response to a user input having two or more input points.

First claim

The invention claimed is:

1. A machine readable non-transitory medium storing one or more programs for execution by one or more processing units of a data processing system, the one or more programs including instructions for:
displaying two or more windows of an application;
receiving an event;
determining whether the event is a hand event that is based on a user input that includes one or more input points touching a display of the system or is a system level event that is not a hand event; and
in accordance with a determination that the event is a hand event based on a user input, routing the event to a window that received the user input and routing the event from the window to an appropriate control of the application by calling a mouse function or a gesture function for processing the event, wherein the window is a respective window of the two or more displayed windows of the application.

2. The medium of claim 1 , wherein the appropriate control comprises a mouse control or a gesture control.

3. The medium of claim 2 , wherein the appropriate control receives one or more function calls, and continues to receive subsequent function calls until the user input is removed from the display.

4. The medium of claim 3 , wherein the one or more function calls include a mouse down or mouse entered function call.

5. The medium of claim 3 , wherein the one or more function calls include three or more gesture function calls, a plurality of which each comprises one of a gesture start event call, a gesture changed event call, and a gesture end call.

6. The medium of claim 5 , wherein the one or more programs include instructions for:
transferring the gesture start event call in response to the user input;
transferring the gesture changed event call in response to a change in the user input; and
transferring the gesture end call when at least one input point associated with the user input is removed from the display.

7. The medium of claim 1 , wherein the one or more programs include instructions for:
in accordance with a determination that the event is a system level event, routing the event to the application.

8. The medium of claim 1 , wherein the system level event indicates that the application should suspend.

9. The medium of claim 1 , wherein the system level event indicates that an orientation of the data processing system has changed.

10. A method, comprising:
at a data processing system with a display, one or more processing units, and memory storing one or more programs for execution by the one or more processing units:
displaying two or more windows of an application;
receiving an event;
determining whether the event is a hand event that is based on a user input that includes one or more input points touching the display or a system level event that is not a hand event; and
in accordance with a determination that the event is a hand event based on a user input, routing the event to a window that received the user input and routing the event from the window to an appropriate control of the application by calling a mouse function or a gesture function for processing the event, wherein the window is a respective window of the two or more displayed windows of the application.

11. The method of claim 10 , wherein the appropriate control comprises a mouse control or a gesture control.

12. The method of claim 11 , wherein the appropriate control receives one or more function calls, and continues to receive subsequent function calls until the user input is removed from the display.

13. The method of claim 12 , wherein the one or more function calls include a mouse down or mouse entered function call.

14. The method of claim 12 , wherein the one or more function calls include three or more gesture function calls, a plurality of which each comprises one of a gesture start event call, a gesture changed event call, and a gesture end call.

15. The method of claim 14 , further comprising:
transferring the gesture start event call in response to the user input;
transferring the gesture changed event call in response to a change in the user input; and
transferring the gesture end call when at least one input point associated with the user input is removed from the display.

16. The method of claim 15 , further comprising:
generating a zoom to scale setting for a window or a view of the touch device in response to the change in the user input.

17. The method of claim 10 , further comprising:
in accordance with a determination that the event is a system level event, routing the event to the application.

18. The method of claim 10 , wherein the user input rotates to invoke a gesture event that performs a rotation transform on a view associated with the user input.

19. The method of claim 10 , wherein the system level event indicates that the application should suspend.

20. the method of claim 10 , wherein the system level event indicates that an orientation of the data processing system has changed.

21. An electronic device comprising:
a display integrated with an input panel;
one or more processing units coupled to the input panel; and
memory storing one or more programs for execution by the one or more processing units, the one or more programs including instructions for:
displaying two or more windows of an application;
receiving an event;
determining whether the event is a hand event that is based on a user input that includes one or more input points touching the display or is a system level event that is not a hand event; and
in accordance with a determination that the event is a hand event based on a user input, routing the event to a window that received the user input and routing the event from the window to an appropriate control of the application by calling a mouse function or a gesture function for processing the event, wherein the window is a respective window of the two or more displayed windows of the application.

22. The device of claim 21 , wherein the appropriate control comprises a mouse control or a gesture control.

23. The device of claim 22 , wherein the appropriate control receives one or more function calls, and continues to receive subsequent function calls until the user input is removed from the display.

24. The device of claim 23 , wherein the one or more function calls include a mouse down or mouse entered function call.

25. The device of claim 23 , wherein the one or more function calls include three or more gesture function calls, a plurality of which each comprises one of a gesture start event call, a gesture changed event call, and a gesture end call.

26. The device of claim 25 , wherein the one or more programs include instructions for:
transferring the gesture start event call in response to the user input;
transferring the gesture changed event call in response to a change in the user input; and
transferring the gesture end call when at least one input point associated with the user input is removed from the display.

27. The device of claim 21 , wherein the one or more programs include instructions for:
in accordance with a determination that the event is a system level event, routing the event to the application.

28. The device of claim 21 , wherein the system level event indicates that the application should suspend.

29. The device of claim 21 , wherein the system level
