避免在Matlab GUI中中断回调函数(Avoid interruption of callback functions in Matlab GUI)

 我有一个Matlab GUI，需要很长时间来执行一些回调函数。 此外，这些功能包括以下代码：  
 drawnow('expose');
 pause(handles.data.delay);
 
 我想避免那些回调执行被中断，以避免在用户按下其他按钮时数据不一致。 因此，我将图形设置修改为：  
set(handles.figure, 'BusyAction','cancel', 'Interruptible','off');
 
 但是，回调仍然中断。 我怎么能避免呢？  
 注意：我认为问题是我需要将'BusyAction'和'Interruptible'值传播到我GUI中的所有控件，有没有办法自动执行？ 例如，在生成GUI之前修改默认值。 

I have a Matlab GUI that needs a high time to execute some callback functions. Besides, these functions include the following code: 
 drawnow('expose');
 pause(handles.data.delay);
 
I want to avoid that those callback executions get interrupted in order to avoid data inconsistency if the user presses other buttons. Thus, I modify the figure settings as: 
set(handles.figure, 'BusyAction','cancel', 'Interruptible','off');
 
However, the callbacks are still interrupted. How can I avoid it? 
Note: I think that the problem is that I need to propagate the 'BusyAction' and 'Interruptible' values to all the controls in my GUI, is there any way to do it automatically? Like, for example, modifying the default value before generating the GUI.

 如前所述，您可能不需要芹菜。 以下是来自案例2的示例： https ： //zapier.com/blog/async-celery-example-why-and-how/ 。 它完全为我工作：  
from time import sleep
import json
from django.http import HttpResponse
from django.shortcuts import render

def main_view(request):
    return render(request, 'index.html')

def ajax_view(request):
    sleep(10) #This is whatever work you need
    pi1 = "This is pi1" #I just made pi1/pis1 random values
    pis1 = "This is pis1"
    context = {
        "pi1" : pi1,
        "pis1" : pis1,
    }
    data = json.dumps(context)

    return HttpResponse(data, content_type='application/json')
 
 我的index.html包含：  
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Main View</title>
    <script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
    <script>
    $(document).ready(function(){
        $.ajax({
            url: "/test_ajax/",
        }).done(function( data) {
            $("#pi1").text(data.pi1);
            $("#pis1").text(data.pis1); 
        });
    });
</script>
  </head>
  <body>
      <h1 id = "pi1">Loading</h1>
      <h1 id = "pis1">Loading</h1>
  </body>
</html>
 
 我的urls.py包含：  
from django.conf.urls import include, url
from django.contrib import admin
from testDjango.test import main_view, ajax_view

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^test/', main_view),
    url(r'^test_ajax/', ajax_view)
]
 
 当我访问localhost时会发生什么：8000 / test /是我立刻看到的：  
   
 大约10秒后，我看到：  
   
 这个想法是，你立即返回你的页面，并使用jquery获取操作的结果，每当完成并相应地更新你的页面。 您可以添加更多内容，例如进度条/加载图像等。例如，您可以在后台处理pi1和pis ，并在完成后将其加载到HTML中。 

As is said previous, you might not need celery. Here's an example derived from case 2 of this: https://zapier.com/blog/async-celery-example-why-and-how/. It's fully working for me: 
from time import sleep
import json
from django.http import HttpResponse
from django.shortcuts import render

def main_view(request):
    return render(request, 'index.html')

def ajax_view(request):
    sleep(10) #This is whatever work you need
    pi1 = "This is pi1" #I just made pi1/pis1 random values
    pis1 = "This is pis1"
    context = {
        "pi1" : pi1,
        "pis1" : pis1,
    }
    data = json.dumps(context)

    return HttpResponse(data, content_type='application/json')
 
My index.html contains:  
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Main View</title>
    <script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
    <script>
    $(document).ready(function(){
        $.ajax({
            url: "/test_ajax/",
        }).done(function( data) {
            $("#pi1").text(data.pi1);
            $("#pis1").text(data.pis1); 
        });
    });
</script>
  </head>
  <body>
      <h1 id = "pi1">Loading</h1>
      <h1 id = "pis1">Loading</h1>
  </body>
</html>
 
And my urls.py contains: 
from django.conf.urls import include, url
from django.contrib import admin
from testDjango.test import main_view, ajax_view

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^test/', main_view),
    url(r'^test_ajax/', ajax_view)
]
 
What happens when I visit localhost:8000/test/ is that I instantly see:  
 
After about 10 seconds, I then see: 
 
The idea is that you return your page instantly and use jquery to fetch the result of the operation whenever that's finished and update your page accordingly. You can add more things like progress bars/loading image etc. For your example, you can do the processing for pi1 and pis in the background and load it into the HTML after that's finished.
