Question: Are there any future activities to provide GUI programming in MATFOR? Answer: MATFOR GUI System is one component to be included in the future release of MATFOR 4. It will facilitate application-building to enhance interface friendliness. It allows users to create an interface of their preference with MATFOR GUI Builder; one can easily embed the MATFOR widget component into the common UI design environment such as WIN32, BCB, MFC, QT, X11 and Motif. With the help of GUI Builder, the interface can be customized and saved into a MFUI file based on XML format. MATFOR GUI System then integrates the MFUI file with MATFOR libraries to generate an application. Such application can be executed in common C++ compilers(Intel C++, Visual C++)and Fortran compilers under both LINUX and Windows operating systems. This is one innovation that makes MATFOR different to other applications.
