如何在gtk上添加text_view滾動條？

Question

我已經使用此功能>>

text_v = gtk_text_view_new() 

BT這裏滾動不工作，以及如何TextView的大小設置添加txtview，都用這一個= >>

gtk_widget_set_size_request(text_v,400,200); 

BT也不工作

這是我做的方式：

#include<gtk/gtk.h> 

int main(int argc, char* argv[]) 
{ 
    GtkWidget *textview, *window, *scrolledwindow; 
    GtkTextBuffer *buffer; 

    gtk_init(&argc, &argv); /*void gtk_init (int *argc,char ***argv);*/ 
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 

    gchar* sample_text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit,\n" \ 
     "sed do eiusmod tempor incididunt ut labore et dolore magna\n" \ 
     "aliqua. Ut enim ad minim veniam, quis nostrud exercitation\n" \ 
     "ullamco laboris nisi ut aliquip ex ea commodo consequat.\n"\ 
     "Duis aute irure dolor in reprehenderit in voluptate velit\n"\ 
     "esse cillum dolore eu fugiat nulla pariatur. Excepteur sint\n"\ 
     "occaecat cupidatat non proident, sunt in culpa qui officia\n"\ 
     "deserunt mollit anim id est laborum."; 

    textview = gtk_text_view_new(); 
    gtk_widget_set_size_request(textview, 400, 200); // This is but a request. The sizes are not guaranteed. 
    scrolledwindow = gtk_scrolled_window_new(NULL, NULL); 

    buffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(textview)); 
    gtk_text_buffer_set_text(buffer, sample_text, -1); 

    gtk_container_add(GTK_CONTAINER(scrolledwindow), textview); 
    gtk_container_add(GTK_CONTAINER(window), scrolledwindow); 
    gtk_widget_show_all(window); 

    gtk_main(); 

    return 0; 
} 

我如果你需要自定義滾動窗口，那麼值得看看here。
