Программа WxPython продолжает сбой консоли

Question

Я уже давно работаю над этой программой. В основном это программа хранения магазина и по какой-то причине, когда я пытаюсь открыть и просмотреть информацию о поставщике, программа вылетает после того, как я ее просмотрю. Консоль просто не позволит мне запускать другие команды.

Вот полный код:

#Place imports here 
import wx 
from sqlite3 import * 
#---------------------------------------------------------------------------    
text1='Name:' 
text2='Address:' 
text3='Contact Number:' 
text4='Alternate Number:' 
text5='Email ID:' 
text6='CST Number :' 
text7='VAT Number:' 
global datalist

    app=wx.App() 
    frame=MainMenu(parent=None,id=-1) 
    frame.Show() 
    app.MainLoop() 

Порция дает мне неприятности это: класс ViewSupplierDetail (wx.MiniFrame):

  def __init__(self,parent,id): 


       viewsupplierbox=wx.SingleChoiceDialog(None, 'Choose Supplier', 'View Supplier Details', datalist2[0][0]) 
       if viewsupplierbox.ShowModal()==wx.ID_OK: 
        answer=viewsupplierbox.GetStringSelection() 



        wx.MiniFrame.__init__(self,parent,id,'View Supplier Details',size=(320,350)) 
        wx.MiniFrame.CenterOnScreen(self) 
        viewsupplierdetailpanel=wx.Panel(self) 


        st1=wx.StaticText(viewsupplierdetailpanel, label=text1, pos=(10,10)) 
        st2=wx.StaticText(viewsupplierdetailpanel, label=text2, pos=(10,50)) 
        st3=wx.StaticText(viewsupplierdetailpanel, label=text3, pos=(10,90)) 
        st4=wx.StaticText(viewsupplierdetailpanel, label=text4, pos=(10,130)) 
        st5=wx.StaticText(viewsupplierdetailpanel, label=text5, pos=(10,170)) 
        st6=wx.StaticText(viewsupplierdetailpanel, label=text6, pos=(10,210)) 
        st7=wx.StaticText(viewsupplierdetailpanel, label=text7, pos=(10,250)) 

        closebutton=wx.Button(viewsupplierdetailpanel, label='Ok', pos=(110,270),size=(90,30))    

        self.Bind(wx.EVT_BUTTON,self.OnClose,closebutton) 


      def OnClose(self,e): 

       self.Close(True) 

Любые идеи?

Answer 1

Немного поиграв с этим, я предполагаю, что соединение с SQLite никогда не закрывается, что может случиться. Вы действительно должны поместить код подключения в свой основной класс, а затем передать объект соединения другим классам при их создании. Затем каждый из других классов может создавать объект-курсор для использования для своих запросов, вставок, выбора и т. Д. Когда вы закрываете другие фреймы, вы можете очищать свои курсоры. Затем, когда вы закроете свой класс MainMenu, вы можете закрыть соединение с базой данных, и он должен вернуться правильно.
