    Abstract: Graphical applications usually allow an image to be displayed according to a display scale. A method of adjusting the display scale during modification of the image in such an application is disclosed. The method comprising the steps of responding to user selection of a modification to be performed on said image by storing the display scale. Then adjusting the display scale during modification of the image; and responding to user completion of the modification, by returning to the stored display scale. In a preferred embodiment, the velocity of a pointing device is measured and the display scale adjusted as a function of the velocity of the pointing device during graphical modification before the display of the image is re-centered on the pointing device position.

    Abstract: In many situations, the objective of data entry is to obtain a complex or structured value. This has traditionally been accomplished by providing a discrete entry field for each element of data entry. By extending the notion of an entry filter, and introducing the notion of a discrete editable element within an entry field, it is possible to apply a structure to that entry field. A management component enables one or more entry filters to be associated in turn with each editable element, and ensures that the entry filters are applied correctly to the appropriate elements.

    Abstract: A framework supporting presentation of help information via a computer system user interface in response to the proximity of an input device pointer to an interface area associated with a user interface component. The framework provides generic methods which remove from user interface components much of the task of managing the presentation of help information. The framework supports presentation of help information for a platform-independent component programming environment and supports presentations in a plurality of different styles (such as text, audio, animating graphics, etc) by means of selectable presentation methods.
