A graphical programming system (1) allows a user to visually create a program. The system employs and input unit (12) and a display (11). The system includes, for example, a graphic-component memory (3) storing graphic components each corresponding to a program that achieves a task such as an operation task or a database task, and displaying the graphic components on the display (11), a task memory (5) storing the programs corresponding to the graphic components and providing the graphic-component memory (3) with data obtained by executing the programs, and a graphic component generator (6) automatically generating data on the graphic components and storing the data in the graphic-component memory (3).
A graphical programming system, comprising:
A graphical programming system letting a user enter instructions through input means to manipulate graphic components displayed on a display, to create a new graphic component and a corresponding new program, comprising:

1. Field of the Invention
The present invention relates to a programming system, and particularly, to a graphical programming system that displays graphic components each corresponding to a program that carries out a task such as an operation task or a database task. A user directly controls the graphic components with, for example, a mouse, to make a program.
This programming system enables a user to freely combine the graphic components and easily create or edit application programs.
Other objects and features of the present invention will be described hereinafter in detail by way of preferred embodiments with reference to the accompanying drawings, in which:
FIG. 1 shows the principle of the present invention;
FIG. 2A shows the details of a graphic-component memory and a task memory according to the present invention;
FIG. 1 shows the principle of a graphical programming system 1 according to the present invention. A user manipulates an input unit 12 such as a keyboard or a mouse, to enter instructions into the system 1. The system 1 has a CPU and memories to display data on a display 11, such as a CRT, according to the instructions. The system 1 has an inclusive-relationship specifier 2, a graphic-component memory 3, a data-structure converter 4a, a process-structure converter 4b, a task memory 5, a graphic-component generator 6, a representative-value changer 7, a data-link unit 8, an event manager 9, and an inclusive-relationship manager 10.
The inclusive-relationship specifier 2 receives user's instructions through the input unit 12, moves a child graphic component onto a parent graphic component on the display 11 according to the instructions, and inclusively relates the parent and child graphic components to each other. The output of the parent component is passed to the child component. The inclusive-relationship specifier 2 edits the inclusive relationship between graphic components by copying, deleting, combining, or decomposing the graphic components. The inclusive relationship is synonymous with the parent-child relationship between graphic components one of which serves as a parent and is arranged under the other that serves as a child component on the display 11.
FIG. 2A shows the details of the graphic-component memory 3 and task memory 5. The display 11 in FIG. 2A shows a graphic component A, i.e., a base sheet, a graphic component B, i.e., a meter disposed on the graphic component A, and a graphic component C, i.e., a slider having a graphic component D, i.e., a cursor. The cursor D and an indicator of the meter B move in response to each other. The inclusive-relationship manager 10 shows that the graphic component A is the parent of the graphic component B.
