Hello! Everybody,
I am planning to design a GUI for an external .cpp application. I am using RedHat Linux with Qt3.3.3. I want user to select some data from GUI like int variable; string name; etc and then GUI should send this selected data as arguments to the external .cpp application for its calculation. And finally after calculations are over in external application i need to send the result to GUI for displaying it to the user.

For example i have: -
In Qt project: - i.) main.cpp ii.)gui.cpp iii.)gui.h
In External application: - i.) MyProgram.cpp working using normal c++ headers & libraries.

"MyProgram.cpp is not a part of the Qt project, its an external application"

I will be obliged if suggested proper path/direction to do the desired work.

Thanks very much in advance.
