检查窗口是否在当前桌面上？

Question

我怎么检查一个pygtk窗口是否在当前桌面上？

我正在修复的一个程序里有：

if self.pymp.window.get_property('visible'):
    self.pymp.window.hide()
else:
    self.pymp.window.move(self.pymp.position[0], self.pymp.position[1])
    self.pymp.window.show()
    self.pymp.window.present()

我想把：

if self.pymp.window.get_property('visible'):

替换成：

if self.pymp.window.get_property('visible') and window_is_on_current_workspace(self.pymp.window):

我可以用wnck来实现window_is_on_current_workspace(window)，代码如下：

def window_is_on_current_workspace(window):
    import wnck
    v = wnck.screen_get_default() # needed due to known bug
    xid = window.window.xid
    win = None
    while win is None:
        win = wnck.window_get(xid)
        if gtk.events_pending():
            gtk.main_iteration()
    wor = win.get_screen().get_active_workspace()
    return win.is_on_workspace(wor)

这个方法可以用，但感觉不太好。有没有更好的办法呢？

你可以使用wnck。下面是一个示例，

from gi.repository import Wnck # import wnck for gtk2

screen = Wnck.Screen.get_default()

def window_is_on_current_workspace(window):
    for win in screen.get_windows():
        if win.get_pid() == os.getpid(): # You could use other methods to determine if you've the right window, like window.name; Just make sure you can uniquely identify it
            return win.get_workspace() == s.get_active_workspace()

        # This works if you have only one window per process, it's just an example. You can use any method to match your gtk window with the x11 window returned by wnck.Screen
