Abstract

A method and system are disclosed for controlling the movement of a graphical pointer displayed within a display device of a data processing system having a graphical pointing device. According to the present invention, a widget, a predefined region within a graphical display, and a graphical pointer are displayed within the display device of the data processing system. When the graphical pointer is displayed at positions within the widget, a first relationship correlates manipulation of the graphical pointing device and movement of the graphical pointer within the display device. Conversely, when the graphical pointer is displayed at positions without the widget, a second relationship correlates manipulation of the graphical pointing device and movement of the graphical pointer within the display device. In response to manipulation of the graphical pointing device, movement of the graphical pointer is determined in accordance with the first relationship when the graphical pointer is displayed at positions within the widget and in accordance with the second relationship when the graphical pointer is displayed at positions without the widget, wherein control of the graphical pointer is enhanced.

Claims

1. A method for controlling the movement of a graphical pointer displayed within a display device of a data processing system, said data processing system including a graphical pointing device having a selection means associated therewith, said method comprising:

displaying a predefined region within said display device, wherein said predefined region is a portion of an output display of said display device;

displaying a graphical pointer within said display device;

defining a first relationship that correlates manipulation of said graphical pointing device and movement of said graphical pointer when said graphical pointer is displayed within said predefined region, wherein said first relationship specifies that said displacement of said graphical pointer in response to manipulation of said graphical pointing device is zero unless said selection means is activated;

defining a second relationship which correlates manipulation of said graphical pointing device and movement of said graphical pointer when said graphical pointer is displayed outside said predefined region;

in response to a manipulation of said graphical pointing device, moving said graphical pointer in accordance with said first relationship when said graphical pointer is displayed at positions within said predefined region and in accordance with said second relationship when said graphical pointer is displayed at positions outside said predefined region.

2. The method for controlling the movement of a graphical pointer of claim 1, wherein said step of defining a first relationship comprises the step of defining a relationship in which said graphical pointer has a greater displacement in response to an incremental manipulation of said graphical pointing device than in said second relationship.

3. The method for controlling the movement of a graphical pointer of claim 2, wherein said step of defining said first relationship comprises the step of defining a relationship equal to said second relationship plus a positive constant.

4. The method for controlling the movement of a graphical pointer of claim 1, wherein said step of defining a first relationship comprises the step of defining a relationship in which said graphical pointer has a smaller displacement in response to an incremental manipulation of said graphical pointing device than said graphical pointer has in said second relationship when said selection device is activated.

5. The method for controlling the movement of a graphical pointer of claim 4, wherein said step of defining said first relationship comprises the step of defining a relationship equal to said second relationship minus a positive constant.
