Abstract

A computer system has a plurality of input pointing devices, such as a mouse, a track ball, a pointing stick, a tablet or a touch screen. Each of the plurality of input devices connected to the computer system has different parameters associated with a double-click operation, which different parameters are stored in separate registers under control of the operating system. Separate device drivers are associated with each input device, each device driver using the associated double-click parameters as stored by the operating system.

Claims

1. A method comprising:

setting up each input device in a data processing system, each input device being from a plurality of input devices, such that each input device has a double-click interval time that is independent of double-click times of other input devices in the plurality of input devices, the double-click interval times being a time interval between clicks in a double-click input event, wherein a double-click input event is performed on a touch panel, and wherein the double-click input event is determined by double-click interval times that are different if the touch panel is double-clicked with a stylus pen or with a finger, and wherein the finger is recognized by having a larger contact area with the touch panel than the stylus pen.

2. The method of claim 1, wherein a time interval between clicks in a double-click is longer for a double-click by the finger than a double-click by the stylus pen.

3. A computer program product, residing on a computer usable medium, the computer program product comprising:

computer program code for setting up each input device in a data processing system, each input device being from a plurality of input devices, such that each input device has a double-click interval time that is independent of double-click times of other input devices in the plurality of input devices, the double-click interval times being a time interval between clicks in a double-click input event, wherein a double-click input event is performed on a touch panel, and wherein the double-click input event is determined by double-click interval times that are different if the touch panel is double-clicked with a stylus pen or with a finger, and wherein the finger is recognized by having a larger contact area with the touch panel than the stylus pen.

4. The computer program product of claim 3, wherein a time interval between clicks in a double-click is longer for a double-click by the finger than a double click by the stylus pen.

5. A system comprising:

means for setting up each input device in a data processing system, each input device being from a plurality of input devices, such that each input device has a double-click interval time that is independent of double-dick times of other input devices in the plurality of input devices, the double-click interval times being a time interval between clicks in a double-click input event, wherein a double-click input event is performed on a touch panel, and wherein the double-click input event is determined by double-click interval times that are different if the touch panel is double-clicked with a stylus pen or with a finger, and wherein the finger is recognized by having a larger contact area with the touch panel than the stylus pen.

6. The system of claim 5, wherein a time interval between clicks in a double-click is longer for a double-click by the finger than a double-click by the stylus pen.
