Thread 中的 Python GTK 窗口
我有一个 CLI 应用程序，它正在挖掘一些数据，在需要时启动一个线程，创建包含一些信息的 GTK 窗口。然而，CLI（主线程）仍然在后台分析数据，因此可能会创建大量窗口。如果我关闭窗口，销毁事件实际上会被触发，我在 CLI 中得到了一条调试行，但窗口被锁定。
我必须使用一些神奇的命令？
我在主线程中创建这样的窗口：
gtk.gdk.threads_init()
notifyWindow = NotifyWindow()
notifyWindow.start()
这是 NotifyWindow(Thread).destroy
def destroy(self, widget, data=None):
print "destroy signal occurred"
gtk.main_quit()
这是 NotifyWindow(Thread).run
def run(self):
self.window = gtk.glade.XML( "hadinfo.glade" )
self.window_main = self.window.get_widget("window_main")
if (self.window_main):
self.window_main.connect("destroy", self.destroy)
self.window_main.connect("delete_event", self.delete_event)
self.button_cancel = self.window.get_widget("button_cancel")
self.button_cancel.connect("clicked", self.destroy)
self.window.get_widget("window_main").show()
gtk.main()
I have a CLI application, which is digging some data, in case of need, fires up a thread which creates GTK window with some information. However the CLI (main thread) still analyzes the data in the background, so there could be numerous windows created. In case I close the window, the destroy event is actually fired up, I got a debug line in CLI, but the window locks up.
Some magical command that I have to use ?
I create window like this in the main thread:
gtk.gdk.threads_init()
notifyWindow = NotifyWindow()
notifyWindow.start()
This is NotifyWindow(Thread).destroy
def destroy(self, widget, data=None):
print "destroy signal occurred"
gtk.main_quit()
This is NotifyWindow(Thread).run
def run(self):
self.window = gtk.glade.XML( "hadinfo.glade" )
self.window_main = self.window.get_widget("window_main")
if (self.window_main):
self.window_main.connect("destroy", self.destroy)
self.window_main.connect("delete_event", self.delete_event)
self.button_cancel = self.window.get_widget("button_cancel")
self.button_cancel.connect("clicked", self.destroy)
self.window.get_widget("window_main").show()
gtk.main()

使用 gtk.threads_enter() 并保留主要调用应该会有所帮助。

using a gtk.threads_enter() and leave around your main call should help.
