    user interface software interacting with the software application, the user interface software including executable program instructions, which, when executed, cause a data processing system to perform a method comprising;

    receiving a user input that comprises a plurality of input points touching a display of the system;

    transferring a gesture start event function call through an application programming interface from the user interface software to the software application in response to the user input;

    transferring a start gesture function call through the application programming interface to a delegate associated with the software application;

    transferring a gesture changed event function call through the application programming interface from the user interface software to the software application in response to a change in the user input;

    transferring a gesture did change function call through the application programming interface to the delegate;

    transferring a gesture end function call through the application programming interface from the user interface software to the software application when at least one input point associated with the user input is removed from the display; and
