如何从gtk+3构建器中获取解析错误？

GObject *gtk_builder_get_object (GtkBuilder *builder, const gchar *name);

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {
    gtk_init(&argc, &argv);

    GtkBuilder *builder = gtk_builder_new();
    GError *error = NULL;

    // 加载UI文件
    if (!gtk_builder_add_from_file(builder, "ui_file.glade", &error)) {
        g_print("Error loading UI file: %s\n", error->message);
        g_error_free(error);
        return 1;
    }

    // 尝试获取对象
    GObject *object = gtk_builder_get_object(builder, "object_name");
    if (object == NULL) {
        // 获取解析错误的详细信息
        GError *parse_error = NULL;
        gtk_builder_get_error(builder, &parse_error);
        g_print("Error parsing UI file: %s\n", parse_error->message);
        g_error_free(parse_error);
    }

    // 其他操作...

    g_object_unref(builder);
    return 0;
}
