Re: window is not shown

I guess he wants to add some functionality to a regular run() loop.

perhaps I should comment the code some more
--
// working version
#include <gtkmm.h>

int main(int argc, char *argv[])
{
  // create a main application class
  Gtk::Main kit(argc, argv);
  // create a window
  Gtk::Window window;
  // show the window
  window.show();

  while(true)
    // run the main loop forever
    // here the window is shown
    kit.iteration();

  return EXIT_SUCCESS;
}

The difference between the two versions is, that in the second I tell the window to hide and aftewards to show, but in the main loop the window is _not_ shown, although the last command to the window was to show itself. If The 'show_now' is not called, the window is also shown. It seems to me: If a window is shown, then gets the signal to hide itself, after that the signal to show itself before the program gets into the main loop, the hide signal is processed after the show signal, so not in the order of calling. 
I hope, you understand my problem now.

I'm curious.  What is the reason that you're calling Main::iteration()
instead of Main::run()?
