Re: gtk2 equivalent of tk's do_one_loop

I'm an absolute beginner at Gtk2,  but know Perl/Tk
fairly well, and I'm trying to compare how things are done.

In Tk, there is a way to loop through the main event loop
one time, how would I do it in Gtk2?

#!/usr/bin/perl -w
use strict;
use Gtk2;

my $window = Gtk2::Window->new;
$window->signal_connect('destroy', sub { Gtk2->main_quit });

$window->add(Gtk2::Label->new("Hello World"));


print "1\n";

#Gtk2->main;  #what simulates looping?
Gtk2->main_do_event ( 'one_loop' );

Gtk2->main_iteration does one pass through the main loop. it's pretty common
to see the following:
    Gtk2->main_iteration while (Gtk2->events_pending);
in apps. if you're wanting to run a main loop and get time for you to do your
own stuff then take a look at Glib::Timeout->add and (usually not a good idea
to run continually) Glib::Idle->add. those two will let the main loop run
(your program will be responsive) and call the function you provide
periodically so that you can get some processing time.
