#!/bin/env perl
use strict;
use warnings;
use threads;
use Gtk2;
use Glib qw(TRUE FALSE);
$|++;
my $str = 'test';
Gtk2::Gdk::Threads->init();
Gtk2->init();
my $window= Gtk2::Window->new("toplevel");
$window->signal_connect(delete_event => sub { Gtk2->main_quit(); });
$window->set_border_width(10);
my $button = Gtk2::Button->new_with_label("Hello World");
$button->signal_connect(clicked => \&new_thread);
$window->add($button);
$window->show_all();
Gtk2::Gdk::Threads->enter();
Gtk2->main();
Gtk2::Gdk::Threads->leave();
##############################################
sub hello()
{
print "sad:$str\n";
}
sub thread_begin()
{
hello();
my $t = threads->create(\&test);
$t->detach();
}
sub test()
{
# Gtk2::Gdk::Threads->enter();
print "weigun\n";
# Gtk2::Gdk::Threads->leave();
}

复制代码

下面这两句，无论注释与否都不行····
# Gtk2::Gdk::Threads->enter();
# Gtk2::Gdk::Threads->leave();
那个按钮按了第二次就出错了···一大堆错误·····程序的输出信息如下：

sad:test
weigun
sad:test
weigun
