c - 加载使用 Glade 创建的文件时 GTK-Builder 内存泄漏

Question

首先我要向大家道歉，我的英语不好。当我使用 gtk_builder_add_from_files ( builder , "interface.xml "& err) 启动我的 GTK 小部件时，我没有错误，但出现了这些内存泄漏:

两天来我寻找解决方案但徒劳无功。或者有人会想到已经遇到了这个问题？

我在 mac os X El Capitan 上通过“leaks”程序获取此日志，但无法使用 valgrind。当他尝试启动该程序时，他崩溃了。 :(

感谢您的宝贵时间，祝您度过愉快的一天。

您的 .gtkbuilder XML 首先是否正确？它按原样加载，没有适当的预检查或错误处理，任何错误都可能导致泄漏或崩溃。考虑检查 gtk_builder_add_from_file() 的返回代码。如果它为零(这意味着错误)，那么就有问题了。

还要确保您不会丢失指向 GtkBuilder 的指针。如果你想删除它，你必须执行g_object_unref()。

除此之外，您不必担心 GtkBuilder 如何管理内存。
