Hi, when writing a program that uses Gtk3, how can I make it so that the program does something at regular time intervals?
Once Gtk3::main has been called, the program appears to be stuck in a loop or something and does nothing but Gtk3 stuff. I want to use something like Gtk3 to have the program display some information in a window. The program does something at regular intervals, and after it has done its work, the information in the window needs to be updated. There doesn´t appear to be any Gtk3 function that would allow to set some kind of timer which calls a function in regular intervals. Here´s an example taken from http://search.cpan.org/dist/Gtk3/lib/Gtk3.pm: #!/usr/bin/perl use strict; use Gtk3 -init; my $window = Gtk3::Window->new ('toplevel'); my $button = Gtk3::Button->new ('Quit'); my $iwindow = Gtk3::Window->new ('toplevel'); my $image = Gtk3::Image->new_from_file('image.png'); $iwindow->add($image); $iwindow->show_all; $button->signal_connect(clicked => sub { Gtk3::main_quit }); $window->add($button); $window->show_all; my $bwindow = Gtk3::Window->new ('toplevel'); $bwindow->set_title('bar'); my $bar = Gtk3::Statusbar->new(); $bwindow->add($bar); $bar->push($bar->get_context_id('bar'), 'image.png'); $bwindow->show_all; Gtk3::main; print "test\n"; I´ve added a window that displays an image and a status bar. The program doesn´t do anything but the Gtk3 stuff. I need it to do what it´s supposed to do and then update the information in the status bar (or whatever widget is better suited for that) and, perhaps, the image (once I figured out how to get something like a draw area). Somehow suspending Gtk3::main to allow the program to do its work doesn´t seem like a good idea because all the GUI would probably become unresponsive. Perhaps I need to fork the "worker program", but then how would it tell the "display program" what information to display? -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
