在后台线程python/pygtk中运行计算

那么，有没有一种方法可以在后台运行python线程而不锁定其余的python? (我不在乎他们花多长时间，只要他们不锁定我的GUI.我只是不能让我的GUI一次不响应几秒钟).使用sleep语句不起作用，因为我的问题是需要很长时间的单个命令(例如image.load()).解决方案由于您使用的是pygtk，您打过threads_init()吗?对于较新的版本:>>> from gi.repository import GObject>>> GObject.threads_init()对于年长的人:>>> import gobject>>> gobject.threads_init()还要确保不要从线程中调用任何GUI方法，否则应用程序会以奇怪的方式损坏.解决此问题的一种简单方法是使用GObject.idle_add: idle_add(callable，user_data = None，priority = None)->源ID 可呼叫接收(user_data) 在没有更高优先级的情况下添加一个可调用对象 事件挂起到默认主循环.Is there a way to run a python thread in the background without locking down the rest of python during time-consuming instructions?I'm trying to do time-consuming calculations in a background thread of a python (pygtk) application. I understand how threads work. The problem is that each time I run an expensive operation in any thread (example: PIL's image.load() for large images), it blocks all python threads until the operation is completed, even though it is in a separate thread.So, is there a way to run a python thread in the background without locking down the rest of python? (I don't care how long they take as long as they don't lock down my GUI. I just can't have my GUI unresponsive for several seconds at a time). Using sleep statements doesn't work because my problem is with single commands that take a long time (like image.load()). 解决方案 Since you're using pygtk, did you call threads_init()?For newer versions:>>> from gi.repository import GObject>>> GObject.threads_init()And for older ones:>>> import gobject>>> gobject.threads_init()Also make sure you do not call any GUI method from your thread or your application will break in weird ways. An easy way around this is to use GObject.idle_add: idle_add(callable, user_data=None, priority=None) -> source id callable receives (user_data) Adds a callable to be called whenever there are no higher priority events pending to the default main loop. 这篇关于在后台线程python/pygtk中运行计算的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
