gtk TextView小部件在函数中不会更新 [英] gtk TextView widget doesn't update during function

问题描述

我是使用python和gtk进行GUI编程的新手，所以这是一个初学者的问题。
我有一个函数，当按下按钮执行各种任务时会调用它，并且每个任务完成后我都会写入一个TextView小部件。问题是TextView小部件在整个函数完成之前不会更新。我需要它在每个任务完成后更新。

I'm new to GUI programming with python and gtk, so this is a bit of a beginners question. I have a function that is called when a button is pressed which does various tasks, and a TextView widget which I write to after each task is completed. The problem is that the TextView widget doesn't update until the entire function has finished. I need it to update after each task.

推荐答案

在每次更新TextView调用之后

After each update to the TextView call

while gtk.events_pending():
  gtk.main_iteration()

您可以通过自定义函数进行更新：

You can do your update through a custom function:

def my_insert(self, widget, report, text):

  report.insert_at_cursor(text)
  while gtk.events_pending():
    gtk.main_iteration()

从PyGTK FAQ：
如何在长回调或其他内部操作期间强制更新应用程序窗口？

From the PyGTK FAQ: How can I force updates to the application windows during a long callback or other internal operation?
