Python和GTK +：如何创建垃圾回收器友好对象？ [英] Python and GTK+: How to create garbage collector friendly objects?

问题描述

我开始使用GTK +编写一个Python应用程序小工具。最近我决定做一些内存优化，并注意到我创建的大部分PyGTK对象从来都不会被垃圾收集器释放。这个数字不断增长，即使我打开一个窗口并在之后妥善销毁。

I started writing a small application in Python with GTK+ as my widget toolkit. Recently I decided to do some memory optimization and noticed that a most of PyGTK objects I create never gets released by garbage collector. This number keeps growing even if I open a window and properly destroy it afterward.

有人能指出我如何从Python创建和处理GTK +对象。我没有使用Glade或类似的东西。

Can someone point me in the right direction on how to create and handle GTK+ objects from Python. Am not using Glade or anything like that.

另外我注意到创建这样的窗口：

Also I noticed that creating window like this:

class SomeWindow:
   def __init__(self):
      self.window = gtk.Window(type=gtk.WINDOW_TOPLEVEL)

而不是：

Instead of:

class SomeWindow(gtk.Window):
   def __init__(self):
      super(SomeWindow, self).__init__(type=gtk.WINDOW_TOPLEVEL)

您可以给我的任何建议吗？

Any advices you can give me?

推荐答案

您是否调用过.destroy（）？

Did you call .destroy()?

根据

According to the gtk.Widget.destroy docu GTK maintains a list of toplevel windows that will keep a reference alive.

在使用任何Python析构函数的情况下，它们也可以防止循环引用被释放。

And in case you use any Python destructors, they can also prevent cyclic references from being freed.
