I am new with Qt and i would like to ask if I can build a program that has an input number that when a push a button the number is entered to a file .sp in a particular place, the file .sp is code for an electronic circuit simulation which runs with the program HSpice. I also want a button that after pressing it i can run the file .sp through HSpice.
Thank you very much
I don't really know HSpice, but if the file format is not proprietary, you could write your own C++ classes that would interact with this file format. You'll then connect a QPushButton instance to a function that puts the data where you want to.
The same thing goes for running the .sp file through HSpice.
I would point you to the excellent documentation to get you started.
