i was tryign to make a gui in fortran, realized that's way too mcuh work and pain in the ass, so the easiest way seems to be make a interface to get the paramaters, output to file then run the program with the input from file. i got the output to file from the program fine, now all i gotta do is run the fortran program. so the question is, how do i run a program or a bash script from QT?

the QT program i have now is basicly a form and when i type in the info, i press a button everythign goes to a text file. what i want is to be able to press a button and have it run the fortran program that reads the data file in the background. that program would output to a file, then when the fortran program is done running, the gui program reads the output file then print it on the screen.

thx

I don't think QT provides a method to run an external command. But that's OK because QT uses C++, so you can just use the system() function. See You will need to include the stdlib.h header in the file you want to call system() from.
Then just do:
where command is a regular string (i.e. double-quoted or NULL-terminated; you can also use a QString here by passing the return value of its latin1() method). The string should contain the command to run, exactly as you would type it in at your shell's command line. See for details on how to cope with command-line arguments and unusual characters.

After running this, the value of rtn will hold the return value of the command, assuming the command ran successfully.

I don't know QT, but I've heard the name qtProcess (or similar) and figured...

You might also want to use your programming language's built-in interface to the shell;
in C and C++, that's `system', in python it's `os.system', for *, well GIYF

Could you write the fortran program as a filter and have a bash or tcl wrapper piece everything together?
