python - gtk treeview - 具有实时更新的列表存储

发布于 2024-09-06 10:18:20 字数 983 浏览 1 评论 0原文

我在尝试获取实时更新时遇到树视图列表存储问题，我创建了一个示例来模拟我想做的事情。我希望 liststore1 每次循环都更新。

应该更新树视图列“速度”并每秒给它一个不同的数字，像下载管理器之类的东西。

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()

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()

如果这是您的完整代码，则您缺少 GTK 主循环调用。

您需要做两件事（按此顺序）

1 - 将窗口的 destroy 信号连接到调用 gtk.main_quit() 的函数

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

window.connect('destroy', on_destroy)

2 - 启动 GTK 主循环：

gtk.main()

这是您的应用程序有效启动的位置，并且它将显示为挂起在该行，直到调用 gtk.main_quit() 为止。

更一般地说......你应该清理一下代码:)看看 " PyGTK 教程中的 Hello World" 演示 - 它基本上涵盖了这些要点以及更详细的信息。你会发现遵循它们的一般结构会有很大帮助。

如果您想要定时更新，请查看函数 timeout_add 和 timeout_add_seconds - 根据您的 PyGTK/PyGobject 版本，这些将位于 glib 或 gobject 模块中。

（顺便说一句，GTKBuilder XML 文件通常具有 .ui 扩展名，尽管 Glade 并不知道。）

If that's your full code, you're missing the GTK main loop invocation.

You need to do two things (in this order)

1 - Connect your window's destroy signal to a function that calls gtk.main_quit()

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

window.connect('destroy', on_destroy)

2 - Start the GTK main loop:

gtk.main()

This is where your app is effectively launched, and it will appear to hang at this line until gtk.main_quit() is called.

More generally... you should clean up the code a bit there :) Look at the "Hello World" demo from the PyGTK tutorial - it basically covers those points and more in greater detail. You'll find that following their general structure for things helps immensely.

If you want timed updates, look at the functions timeout_add and timeout_add_seconds - depending on your version of PyGTK/PyGobject these will be in the glib or gobject modules.

(Incidentally, GTKBuilder XML files typically have the .ui extension, even though Glade doesn't know it.)
