Re: print statements on console while window is running

[Bob Caryl <bob fis-cal com>]

I don't know why you would want constant output to a console while
running a window; nevertheless, in order for your code to display a
window and also constantly output text to the console, you need it to
look like this:

<start code>

#include <gtkmm.h>
#include <iostream>
using namespace std;
using namespace Gtk;

int main(int argc, char *argv[])
{

  Main kit(argc, argv);

  Window window;

  window.show();

  while (1)
  {
    while(Main::events_pending())
    {
      Main::iteration();
    }
    cout << "----------------------" << endl;

  }

  return 0;
}

<end code>

Be advised that in the above program, closing the window will not halt
your program as written.  You will have to close it from the console
using "Ctrl-c".

A better way to do this would be:

<start code>

#include <gtkmm.h>
#include <iostream>
using namespace std;
using namespace Gtk;

bool print_to_console(void)
{
   cout << "----------------" << endl;
   return true;
}

int main(int argc, char *argv[])
{

  Main kit(argc, argv);

  Window window;

  // connect to the application's idle loop signal to print your console output
  Glib::signal_idle().connect(sigc::fun_ptr(&print_to_console));

  window.show();

  Gtk::Main::run(window);

  return 0;
}

<end code>

This method allows you to end your program by closing your window, and
also has the benefit of not monopolizing the computer's CPU in a tight loop.

I hope this helps.
