检查window是否在当前桌面上？

Question

如何检查pygtk窗口是否在当前桌面上？

我正在修复的一个程序有：

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()

我想替换：

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

通过以下方式：

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

我可以像这样用wnck实现window_is_on_current_workspace(window)：

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)

它可以工作，但它很讨厌。有没有更好的方法来做这件事？

您可以使用wnck。这是一个示例，

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
