gtk_widget_show_all(window)错误

linhanzu

我编了一个小程序，编译运行时出错：
GLib-GObject-CRITICAL **: gtype.c:1875: initialization assertion failed, use g_type_init() prior to this function

GLib-GObject-CRITICAL **: file gobject.c: line 615 (g_object_new): assertion `G_TYPE_IS_OBJECT (object_type)' failed
段错误

我的程序大体时这样的：
int
main (int argc, char *argv[])
{
...
create_window ();/调用创建创口的函数
...
}
GtkWidget*
create_window (void)
{
......
gtk_widget_show_all(window);
}
    我用xxgdb调试设置断点，单步执行，运行到gtk_widget_show_all(window)这里时就出现上面的错误。
    都好几天了，郁闷啦，求助各位啦！谢谢

把代码全部贴出来. 连你的 window 在什么地方定义地都不知道, 看不出问题.

贴出create_window中与window相关代码

谢谢两位：
GtkWidget *create_window (void)
{
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title (GTK_WINDOW (window), "wwww");
  gtk_signal_connect (GTK_OBJECT (window), "destroy",GTK_SIGNAL_FUNC (my_quit), NULL);
  gtk_widget_set_usize (window, 165, 600);
  gtk_container_set_border_width (GTK_CONTAINER (window), 2);

  vbox = gtk_vbox_new (FALSE, 0);
  gtk_widget_show (vbox);
  gtk_container_add (GTK_CONTAINER (window), vbox);
  gtk_container_set_border_width (GTK_CONTAINER (vbox), 2);

  scrolled_win = gtk_scrolled_window_new (NULL, NULL);
  gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (scrolled_win),
                                  GTK_POLICY_AUTOMATIC, K_POLICY_AUTOMATIC);
  gtk_box_pack_start (GTK_BOX (vbox), scrolled_win, TRUE, TRUE, 0);
  gtk_widget_set_usize (scrolled_win, 150, 300);
  gtk_widget_show (scrolled_win);

  tree = gtk_tree_new ();
  gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW (scrolled_win), tree);
/* select mode  */
  gtk_tree_set_selection_mode (GTK_TREE (tree), GTK_SELECTION_SINGLE);
  gtk_widget_show (tree);
  
  /* 日历构件  */
  frame = gtk_frame_new ("Calendar");
  gtk_widget_show (frame);
  gtk_box_pack_start (GTK_BOX (vbox), frame, TRUE, TRUE, 0);
  gtk_widget_set_usize (frame, 165, 130);
  gtk_container_set_border_width (GTK_CONTAINER (frame), 2);
  calendar = gtk_calendar_new ();

  table = gtk_table_new (2, 3, FALSE);
  gtk_widget_show (table);
  gtk_box_pack_start (GTK_BOX (vbox), table, TRUE, TRUE, 0);
  gtk_widget_set_usize (table, 165, 50);
  gtk_table_set_row_spacings (GTK_TABLE (table), 2);
  gtk_table_set_col_spacings (GTK_TABLE (table), 4);
  gtk_container_set_border_width (GTK_CONTAINER (table), 2);

然后table里面是几个按钮：
  。。。。。。
  gtk_widget_show_all (window);
}

nt main (int argc, char *argv[])
{
  gtk_init (&argc, &argv);
  create_window ();
  gtk_main ();
  return 0;
}

大体上就这些了！谢谢了

你贴出的代码都没问题
如果没什么保密就全贴出来

没什么保密的。只是嫌麻烦，看了不爽！
我在以前的系统里面能运行的，重装linux就出现这样的问题了！
郁闷，都好几天了！运行就出现上面的问题，调试也是这样！
帮忙分析一下是object错误吗！

mozilla

出了K_POLICY_AUTOMATIC应改为GTK_POLICY_AUTOMATIC外没什么问题，运行也正常。
你的那些window,vbox,scrolled_win是在哪里定义的。

linhanzu

K_POLICY_AUTOMATIC这个可能是不小心删错了！
window,vbox,scrolled_win都是在creat_window里面定义的！不会错的！，
我以前就可以运行的，真是的，重装系统后就这样！

斑竹能给说说这两句到底是什么意思吗！

mozilla

应该是指针没初始化。程序本身应该没什么问题，你重新安装一下gtk和glib试试。

没有源程序，一条一条的看太花时间。
