pyGTK 检测所有窗口移动事件

Question

我想要捕捉每个窗口的配置事件，以创建类似Windows 7的窗口贴靠功能。我知道有一些解决方案是用compiz-fusion，但我的安装是在vmware上运行的，没有硬件加速，无法使用compiz。我想简单写个Python脚本来实现我的需求，但我找不到合适的地方来绑定这个配置事件。

我应该把配置事件的回调绑定到什么地方，或者我需要关注其他不同的事件吗？我试过把它绑定到屏幕和根窗口，使用get_root_window()，但都没有成功。

现在我可以捕捉到所有事件，但问题是每个返回的事件都是GDK_NOTHING类型，所以我无法区分焦点事件、移动事件、关闭事件等等。

#!/usr/bin/python
import pygtk
pygtk.require('2.0')
import gtk, wnck
import inspect

def move_event(e):
    print e.type, e.window
    print inspect.getmembers(e)
    return gtk.gdk.FILTER_CONTINUE

def bind_win(screen, win):
    w = gtk.gdk.window_foreign_new(win.get_xid())
    if w:
        w.set_events(w.get_events() | gtk.gdk.ALL_EVENTS_MASK)
        w.add_filter(move_event)


if __name__ == "__main__":
    screen = wnck.screen_get_default()
    screen.connect("window_opened", bind_win)
    gtk.main()

在拖动窗口时，move_event(e)的一个迭代：

<enum GDK_NOTHING of type GdkEventType> <gtk.gdk.Window object at 0x7f38f72f8730 (GdkWindow at 0x196ce20)> [('copy', <built-in method copy of gtk.gdk.Event object at 0x7f3900513d00>), ('free', <built-in method free of gtk.gdk.Event object at 0x7f3900513d00>), ('get_axis', <built-in method get_axis of gtk.gdk.Event object at 0x7f3900513d00>), ('get_coords', <built-in method get_coords of gtk.gdk.Event object at 0x7f3900513d00>), ('get_root_coords', <built-in method get_root_coords of gtk.gdk.Event object at 0x7f3900513d00>), ('get_screen', <built-in method get_screen of gtk.gdk.Event object at 0x7f3900513d00>), ('get_state', <built-in method get_state of gtk.gdk.Event object at 0x7f3900513d00>), ('get_time', <built-in method get_time of gtk.gdk.Event object at 0x7f3900513d00>), ('put', <built-in method put of gtk.gdk.Event object at 0x7f3900513d00>), ('send_client_message', <built-in method send_client_message of gtk.gdk.Event object at 0x7f3900513d00>), ('send_clientmessage_toall', <built-in method send_clientmessage_toall of gtk.gdk.Event object at 0x7f3900513d00>), ('send_event', 1), ('set_screen', <built-in method set_screen of gtk.gdk.Event object at 0x7f3900513d00>), ('type', <enum GDK_NOTHING of type GdkEventType>), ('window', <gtk.gdk.Window object at 0x7f38f72f8730 (GdkWindow at 0x196ce20)>)]
