c - 如何在 gtk 上添加 text_view 滚动条？

Question

我已经使用这个函数添加了txtview >>

 text_v = gtk_text_view_new()

bt 这里滚动不起作用，还有如何设置 textview 大小，用过这个 =>>

gtk_widget_set_size_request(text_v,400,200);

bt 也不行

我是这样做的:

#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;
}

如果您需要自定义滚动窗口，值得一看here .
