ePh*_*ipe 5 python pygobject gtk3 chromium-embedded
我在CEF Python 3上获得了此代码(link)
...
self.container = gtk.DrawingArea()
self.container.set_property('can-focus', True)
self.container.connect('size-allocate', self.OnSize)
self.container.show()
...
windowID = self.container.get_window().handle
windowInfo = cefpython.WindowInfo()
windowInfo.SetAsChild(windowID)
self.browser = cefpython.CreateBrowserSync(windowInfo,
browserSettings={},
navigateUrl=GetApplicationPath('example.html'))

这段代码[ self.container.get_window()。handle ]不适用于PyGI和GTK3。
我尝试将代码从GTK2移植到GTK3,该怎么办?
编辑:
一些搜索后,我发现了一个尖,使get_window工作:我叫:self.container.realize()之前self.container.get_window() 。但是我还没有Window Handle。
我需要将CEF3窗口放在DrawingArea或任何元素内。如何使用PyGI做到这一点?

我的环境是:
Windows 7的
Python 2.7和Python 3.2

可悲的是,似乎无法在python gobject内省中解决此问题并使其gdk_win32_window_get_handle可用(很久以前就报告了gnome bugtracker中的一个错误)-Python GStreamer和Windows也相当需要它...
因此,我遵循了totaam的建议,并使用ctypes访问gdk_win32_window_get_handle。因为我没有这个经验,所以永远把我带走-嗯,这在某种程度上是一个丑陋的破解-但是在需要时很好...
这是代码:
Gdk.threads_enter()
#get the gdk window and the corresponding c gpointer
drawingareawnd = drawingarea.get_property("window")
#make sure to call ensure_native before e.g. on realize
if not drawingareawnd.has_native():
print("Your window is gonna freeze as soon as you move or resize it...")
ctypes.pythonapi.PyCapsule_GetPointer.restype = ctypes.c_void_p
ctypes.pythonapi.PyCapsule_GetPointer.argtypes = [ctypes.py_object]
drawingarea_gpointer = ctypes.pythonapi.PyCapsule_GetPointer(drawingareawnd.__gpointer__, None)
#get the win32 handle
gdkdll = ctypes.CDLL ("libgdk-3-0.dll")
hnd = gdkdll.gdk_win32_window_get_handle(drawingarea_gpointer)
#do what you want with it ... I pass it to a gstreamer videosink
Gdk.threads_leave()

您必须首先导入GdkX11forget_xid()才能在返回的GdkX11Window.
from gi.repository import GdkX11
...
-windowID = self.container.get_window().handle
+windowID = self.container.get_window().get_xid()
