I have a program that opens a WAV file and then plots the waveform. If the WAV file has 2 channels, two graphs are shown, one for each channel. It’s working fine but I want to add things in the File Menu that I created. So far, I have three buttons: New, Open File, and Close. So far, the Open File and the Close buttons are working fine.
I want to make the program to be able to let the user view several waveforms of several WAV Files at the same time. One option would be to create more graphs, the process would be quite tedious. Another option would be to open another window and this is what I want to do.
However, this is my problem. I made a quick search on how to open an existing program in C++, and so far, the solutions that I encounter involve opening an exe file and the project folder does not contain an exe file.
I also tried to take a quick look on the functions and I can’t find the function that seems to open the window and I can’t seem to find it.
Your best bet is to use fork. Alternatively you could use threads.
