PyGtk -当窗口位置改变时调用函数

Question

我有一个基本的python gtk程序来显示窗口的位置，有没有一种简单的方法来更新它，当它移动?

#!/usr/bin/python
import gtk
class app(gtk.Window):
  def __init__(self):
    super(app, self).__init__()
    self.set_position(gtk.WIN_POS_CENTER)
    self.set_title("Window Position Test")
    self.set_decorated(True)
    self.set_has_frame(False)
    self.set_resizable(False)
    self.set_default_size(320, 50)
    self.connect("destroy", gtk.main_quit)
    vbox = gtk.VBox(spacing=4)
    hbox = gtk.HBox(spacing=4)
    self.pos_label = gtk.Label()
    vbox.add(self.pos_label)
    self.add(vbox)
    self.update_pos()
    self.show_all()

  def update_pos(self):
    ''' Get window position, display + log '''
    pos = str( self.get_position() )
    print( pos )
    self.pos_label.set_label( pos )

app()
gtk.main()

只需在末尾附加"configure-event":

#!/usr/bin/python
import gtk
class app(gtk.Window):
  def __init__(self):
    super(app, self).__init__()
    self.set_position(gtk.WIN_POS_CENTER)
    self.set_title("Window Position Test")
    self.set_decorated(True)
    self.set_has_frame(False)
    self.set_resizable(False)
    self.set_default_size(320, 50)
    self.connect("destroy", gtk.main_quit)
    vbox = gtk.VBox(spacing=4)
    hbox = gtk.HBox(spacing=4)
    self.pos_label = gtk.Label()
    vbox.add(self.pos_label)
    self.add(vbox)
    self.update_pos()
    self.show_all()
    self.connect("configure-event", self.update_pos)

  def update_pos(self, *args):
    ''' Get window position, display + log '''
    pos = str( self.get_position() )
    print( pos )
    self.pos_label.set_label( pos )

app()
gtk.main()
