ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to computer software for creating, modifying, and manipulating charts and diagrams in order to display software programs in the form of flowchart images (i.e., diagrams containing a plurality of boxes, and connecting lines).
2. Description of the Related Art
The use of personal computers has become widespread for a variety of functions and applications in business and education. One such application of computers is their use for producing, printing and displaying graphical images. Still more particularly, a variety of application programs have been developed for creating flowcharts, organizational charts, and various other diagrams. Such existing systems provide for the creation of various drawing elements and their interconnection. For example, there are a variety of complex computer aided design or drafting programs for creating any type of mechanical, electrical and architectural drawings. There are also more simplistic drawing programs for creating only flowcharts or organizational charts.
One major problem with the existing flowcharting and drawing programs is that they are very difficult to use. The complex computer aided design programs usually require a significant amount of training to be used and are typically only used by skilled draftspersons. Even the more simplistic drawing programs with reduced functionality are cumbersome and difficult to use. For example, existing systems require a number of key strokes or inputs from a mouse type controller to create a simple shape or symbol in a chart, such as a rectangular box. To create a flowchart symbol, a symbol is first chosen from the symbol palette or menu displayed on a monitor. The symbol is then dragged and dropped using a mouse type controller into a desired position in the drawing. Alternatively, the symbol could be created and positioned using various other keystrokes or combinations of keystrokes and mouse inputs. Once the symbol has been added, it typically must be connected with other elements in the drawing. This requires similar manipulations of the input device to add a simple connecting line. Having to repeatedly reposition the cursor from one area of the drawing to a palette or menu for adding each element or changing the functionality provided by manipulation of the cursor is highly inefficient. Creating and drawing such drawings is therefore very labor intensive and time consuming. Thus, there is a need for a system that makes drawing elements easier to create.
