A calculator having a hierarchical tree view (HTV) window provides a more efficient method of displaying calculator usage history. The HTV window provides tabs to choose between multiple windows displaying usage history such that more information can be displayed quickly without using more display area than is necessary. The HTV window also provides a view of usage such that expressions listed in the HTV window can quickly be expanded or unexpanded by the user in order to see data associated with that expression. Tool tip information may be provided to the user, displayed expressions may be re-used by double-clicking or dragging and dropping operations, expressions may be grouped into user-defined folders, and symbols may be used for easy identification of expressions, results, or folders. Additionally, usage history may be stored into a file, files may be opened for the purpose of re-using such usage history at a subsequent time, and scripts and functions may be created, executed, and saved for subsequent use.

Graphical calculator with hierarchical view of usage history

Wall panel

A wall panel which provides the attractive look of a tiled wall, but also includes a flat area without grout lines for accepting wallpaper or other decoration. The unit includes sheets of vacuum formed material, having formed in one face thereof a plurality of substantially identical regular polygonal shapes, such as squares, each of these shapes being generally immediately adjacent the neighboring shapes, so that the appearance of grout lines is formed between the adjacent shapes. At least one generally rectangular flat area is formed in the material, that flat area having one dimension substantially greater than the largest dimension of any one of the shapes. The width of the flat area is no larger than the largest dimension of any one of the shapes. Each sheet of material has a vertical edge flange portion formed along one entire vertical edge of the sheet, and adapted to be disposed in relation to a corresponding vertical edge of the next adjacent sheet in such a way that the next adjacent sheet overlies the edge flange. Resulting in the appearance of a smooth connection between adjacent sheets. Inner corner moldings and linear moldings ae provided for dressing the top edges of the sheets and for rounding out the physical installation of the sheets.
