Just a few clues I’ve found about running the same binary without a GUI:
- GTK supports running a program without display:
http://library.gnome.org/devel/gtk/2.12/gtk-General.html#gtk-init-check. This doesn’t tell if it’s possible in wxWidgets though.
I see it calls gtk-init-check in wxApp::Initialize.
I can subclass Initialize, call the original one while suppressing the error message and ignore the return value. It seems to be working.
Any suggestions what to name the command line switches and how to describe them? Is there any traditional standard? I’m currently using: -daemon (or -d) (Enables RPC and runs in the background) -server (Enables RPC)
