我新建了一个testbutton类,继承自gtk.Button,可是为什么只能实例化一个对象？

#!/usr/bin/python

import gtk

class testbutton(gtk.Button):
	
	def button_press(self, widget, event):
       		if event.type == gtk.gdk._2BUTTON_PRESS:
			self.destroy()
            		return gtk.TRUE
                return gtk.FALSE

	def __init__(self,text):
		apply(gtk.Button.__init__,(self,text))
		self.set_label(text)
		self.connect_object("event", self.button_press,None)


window=gtk.Window(gtk.WINDOW_TOPLEVEL)
hbox=gtk.HBox()
hbox.show()
testbutton=testbutton("test0")
testbutton.show()
hbox.pack_start(testbutton,gtk.TRUE,gtk.TRUE,0)

testbutton=testbutton("test1")
testbutton.show()
hbox.pack_start(testbutton,gtk.TRUE,gtk.TRUE,0)

window.connect("destroy",lambda w: gtk.main_quit())
window.add(hbox)
window.show()
gtk.main()

用变量 testbutton 代替了类 testbutton

这里再用 testbutton 已经访问不到上面的那个类了。

python-chinese at lists.python.cn，您好！

为什么我已经运行了，但是却访问不到呢

[root at ctionsofta etc]# /etc/init.d/plone2 status
program running; pid=3834
[root at actionsoft etc]# /etc/init.d/plone2 start
Plone2 instance main is already running. [root at actionsoft etc]# /etc/init.d/plone2 stop
Stopping Plone2 instance main:                             [ 确定 ]
[root at actionsoft etc]# /etc/init.d/plone2 restart
Plone2 is not running. Starting Plone2 instance main:      [ 确定 ]

[root at actionsoft etc]# /etc/init.d/plone2 restart
Stopping Plone2 instance main:                             [ 确定 ]
Starting Plone2 instance main:
                                                           [ 确定 ]



　　　　　　顺颂商祺！
