Question

i am having a issue with treeview liststore trying to get a real-time update, and I created a example to simulate what I d like to do. I want liststore1 updated each loop.

it should update the treeview column speed and give to it a different number every second, something like a download manager.

import gtk
import gtk.glade
import random

builder = gtk.Builder()
builder.add_from_file( ttt.glade )
window = builder.get_object( window1 )
treeview  = builder.get_object( treeview1 )
store = builder.get_object( liststore1 )
column_n = [ File , Size , Speed ]
rendererText = gtk.CellRendererText()


for i in range(10):
    foo = random.randint(100,256)
    list_ =  [( arquivo1.tar.gz ,  10MB ,  %s k/s  % foo)]

for x,y in zip(column_n,range(3)):

    column = gtk.TreeViewColumn(x, rendererText, text=y)
    column.set_sort_column_id(0)    
    treeview.append_column(column)


for list_index in list_:
    store.append([list_index[0],list_index[1],list_index[2]])

window.show_all()

如果是你的全员,你就重新找不到德国克朗的主要假日。

你们需要做两件事(按此顺序排列)

1 - 连接你的窗户<代码>destroy信号,以显示gtk.main_quit()

def on_destroy(widget, user_data=None):
    # Exit the app
    gtk.main_quit()

window.connect( destroy , on_destroy)

2 - 启动德国技术合作公司的主要通道:

gtk.main()

这正是你有效发射的,在打电话到<条码>>>上,这似乎在这条线上消失。

更一般地说,...... 您应当对该法典作一点修改: 查阅 Hello World" demo from the PyGTK tutorial - 基本上涵盖这些要点,更详细。你们发现,根据他们的总体结构,事情大有帮助。

如果你需要时间更新,请查阅以下职能:time_add 和 glib或gobject模块。

(显然,GTKBuilder XML档案通常有.ui的延伸,即使Gladet知道。)
