Scans the argument vector, and strips off all parameters known to GTK+.
Your application may then handle the remaining arguments.
Note: The argument strings themself won't be modified, although the pointers to them might change. This makes it possible to create your own argv of string literals, which have the type 'const char' in standard C++. (You might need to use const_cast<>, though.)
KeySnooper signal Allows you to channel keypresses to a signal handler without registering with the widget.
It is the responsibility of the snooper to pass the keypress to the widget, however, care must be taken that the keypress is not passed twice.
Quit signal You can connect signal handlers to invoke actions when Gtk::Main::quit() has been called.
Note that main loops can be nested by calling Gtk::Main::run() recursively, therefore receiving this signal doesn't necessarily mean the application is about to be terminated. If you want to receive a signal only when the last main loop quits, call connect() with main_level = 1.
