Gtk_combo_box_text_remove_all挂起应用程序

Question

在运行的应用程序中，我要替换的内容 一个“ GTK_COMBO_BOX_TEXT ....”

我愿意

    void initLoadComboBox() {
        struct passwd *pw = getpwuid(getuid());
        const char *homedir = pw->pw_dir;

        GtkTreeModel *tm = gtk_combo_box_get_model(GTK_COMBO_BOX(loadComboBox));
        gtk_list_store_clear(GTK_LIST_STORE(tm));

        DIR* dirp = opendir(homedir);
        struct dirent * dp;

        while ((dp = readdir(dirp)) != NULL) {
            if (strncmp("tkbrain-", dp->d_name, 8) == 0) {
                char *xy = new char[1000];
                strcpy(xy, dp->d_name);
                gtk_combo_box_text_append_text(GTK_COMBO_BOX_TEXT(loadComboBox),
                        xy);
            }
        }
        closedir(dirp);
    }

gtk_combo_box_text_remove_all()的相同问题
