Hi Duncan, I am simply using the solution suggested by Edzard and Greg - just simple window->show(). I am directly using argc and argv from main and I don't want to know what FLTK does with argc and argv and why it stores them inside its own class or namespace.
Basically, my application is supposed to run on Windows as well as Linux. On Windows my application is started by another application that sends command-line arguments in the "/xxx" manner as it goes in Windows world. However, in case of Linux/Unix, I need to parse "-" and "--". I can do all this if I directly parse command-line using the argc and argv args of main(). Or, I can use Boost.Program_Options library to handle all this for me. However, I would be thankful if you can inform me as to the side effects, if there are any at all, if I don't do anything with FLTK's argc and argv and directly use argc and argv of main.
