伙计们,

我要尝试制作一个与我制作的Gtk_tree_view有关的功能, 像这样的错误响应:

(main:8026): Gtk-CRITICAL **: IA__gtk_tree_view_get_model: assertion `GTK_IS_TREE_VIEW (tree_view)' failed

(main:8026): Gtk-CRITICAL **: IA__gtk_list_store_append: assertion `GTK_IS_LIST_STORE (list_store)' failed

(main:8026): Gtk-CRITICAL **: IA__gtk_list_store_set_valist: assertion `GTK_IS_LIST_STORE (list_store)' failed
^C

和来源,你走了:

 void addlist(bahan *unit, const gchar *str)
    {
        GtkListStore *store;
        GtkTreeIter iter; // penyambung store_append and store_set

        store = GTK_LIST_STORE(gtk_tree_view_get_model(GTK_TREE_VIEW(unit->treeview_aktifitas)));

        gtk_list_store_append(store, &iter); // need unary &, coz iter aint define like a pointer
        gtk_list_store_set(store, &iter, 1, str, -1);
    }

正如你所想,“单位”的结构应该是这样的:

  typedef struct
    {
        GtkWidget *window;
        GtkWidget *notebook;
        GtkWidget *start;
        GtkWidget *verbose;
        GtkWidget *settings;
        GtkWidget *about;
        GtkWidget *statusbar;
        GtkWidget *treeview_aktifitas;
        guint statusbar_id;
    } bahan;

并通过此连接:

  unit->treeview_aktifitas = GTK_WIDGET(gtk_builder_get_object(main,"treeview1"));

在实际案例中,我使用'glade 3',并且在glade文件上有两列,如何设置gtk_list_store_set?

非常感谢任何进一步的帮助:)

答案 0 :(得分:2)

好吧,我现在发现了这个错误

    gtk_list_store_set(store, &iter, 1, str, -1);

因为我的专栏是两个,所以我需要

    gtk_list_store_set(store, &iter, 0,"aku", 1, "tes", -1);

其中0表示第一列,1表示下一列,依此类推-_-'
