model suit to skilled users and novices separately, the combination of these two models is selected as the solution of the Culgi GPE. Then in section 3.5, we mainly introduced the design on modules. In design of the interface of the module, we use four information detail level views to show a module while the general data flow editors have two. The new ones we designed mainly help users to improve the programming efficiency. And then we use different widgets in display the parameters of a module and we also make the system to keep consistency of the input. The widgets will help users select or type in right values to a parameter. The design not only satisfies the functionality list in Chapter 2, but also aims at making the whole system easy to learn and easy to use. In the next chapter, some implementation details are presented. - 26 -
Chapter 4 Implementation of the Culgi GPE Chapter 3 suggests three models: the network editor, the sequence editor, and the concept editor. It also points out that the combination of sequence editor and concept editor will be the solution of the Culgi GPE. This chapter will mainly introduce the implementation of the solution. Although the network editor is not a solution to the Culgi GPE, in the prototype we also implemented the prototype to this model in the very beginning. This chapter will also introduce this model very shortly. This chapter first shows the architecture of the whole system, and then explains each component in this architecture. 4.1 System Overview The Culgi GPE will be a part of the Culgi Package. Its main functionality can be described as a bridge for users between Culgi Library and Tcl scripts. This section will give an overview of the implementation of the prototype. It first introduces the implementation language, and then shows the architecture of the whole system. Before implementation, several considerations should be kept in mind. These considerations from the requirements analysis are 1) the system should be platform independent; 2) external software component are the Tcl 8.4 interpreter and Culgi.dll. 4.1.1 Programming languages Python is chosen as the implementation language. Python [7] is an interpreted, interactive, object-oriented programming language. It is selected for the following reasons. 1) As a functional scripts language, Python does not have compile-link cycle. 2) It is cross platform. 3) The Python 2.4 core includes Tcl8.4.dll. Thus it is very easy to run Tcl scripts in Python environment. 4) It is possible to load modules dynamically. That is to say, if a module in the module library is modified when the system (the Culgi GPE) is running, a user does not need to restart the system to accept the changes. 5) It is very easy to create an interface because Tkinter and Tix are integrated inside. Tkinter and Tix can be used to build a graphical interface. - 27 -
