请教如何在GTK中使用线程

ttec_pq

因为没找到相关资料，请高手指点：
包括应该加哪个头文件、使用哪些线程函数、编译时需要添加哪些选项。
谢谢。

gtk_init()之前加上
[code:1]
    g_thread_init(NULL);
#if GTK_MAJOR_VERSION == 2
    gdk_threads_init();
#endif
[/code:1]

gtk_main()之前要加上gdk_threads_enter();，之后要加上gdk_threads_leave();
[code:1]
    gdk_threads_enter();
    gtk_main();
    gdk_threads_leave();
[/code:1]

在线程里对控件进行操作时也要用gdk_threads_enter();和gdk_threads_leave();

比如：
[code:1]
gdk_threads_enter();
gtk_widget_set_usize(label,100,100);
gtk_label_set_text(label,"hello world");
gdk_threads_leave();
[/code:1]

编译时加上-lpthread -lgthread
gtk2是:-lpthread -lgthread-2.0

多谢指教！

另外，下面这个函数到底是干什麽的，看了半天注释也没领会意思：
gtk_toggle_button_set_inconsistent ()

void        gtk_toggle_button_set_inconsistent
                                            (GtkToggleButton *toggle_button,
                                             gboolean setting);

If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a toggle button, and the current values in that range are inconsistent, you may want to display the toggle in an "in between" state. This function turns on "in between" display. Normally you would turn off the inconsistent state again if the user toggles the toggle button. This has to be done manually, gtk_toggle_button_set_inconsistent() only affects visual appearance, it doesn't affect the semantics of the button.
