python - pyGTK 检测所有窗口移动事件

Question

我正在 try catch 每个窗口的配置事件以创建 Windows 7 风格的快照功能。我知道有涉及 compiz-fusion 的解决方案，但我的安装是在 vmware 中运行的，没有硬件加速来运行 compiz。我想一个简单的 python 脚本可以做我想做的事，但我似乎无法找到将配置事件绑定(bind)到的正确位置。

您如何/将配置事件回调绑定(bind)到什么，或者是否有我需要注意的不同事件？我试过使用 get_root_window() 将它绑定(bind)到屏幕和根窗口，但没有成功。

EDIT2

现在我可以捕获所有事件，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。

#!/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()

拖动窗口时 move_event(e) 的一次迭代:

<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)>)]

快速搜索显示 this页面，尽管它是用 C 语言编写的，但可以很好地传达基础知识(您必须 grep 它才能找到“移动窗口”)

配置事件绑定(bind)到应用程序的窗口。

要完成您想要做的事情，您还必须找出屏幕尺寸，它位于 gtk.gdk.screen 中，记录在 here 中。 .
