не может выйти из wxpython

Question

Итак, я думаю, что знаю, что моя проблема, но я не могу понять, как это исправить. Я относительно новичок в wxPython. Я перемещаю некоторую функциональность, которую у меня есть в терминальном скрипте для графического интерфейса, и, похоже, это не так. Я использую anaconda для моего дистрибутива python и добавил wxPython для графического интерфейса. Я хочу, чтобы пользователи могли перетаскивать файлы в текстовые элементы управления, а затем импортировать содержимое файла в dataframes для анализа с помощью pandas. Пока все радуется. Кроме того, что программа не уйдет. Я думаю, что это связано с тем, как я определяю окно и фрейм. Я удалил значительную часть функциональности из сценария, чтобы упростить работу. Пожалуйста, дайте мне знать, что мне не хватает.

Answer 1

Проблема заключается в том, что вы создать только один экземпляр класса MyFileDropTarget, а затем назначить тот же объект с несколькими виджетами. Похоже, вам нужно создать один экземпляр целевого экземпляра для каждого виджета. Я переработан код немного, но вот один из способов сделать это:

import wx 
import os 
#import pandas as pd 
#import numpy as np 
#import matplotlib.pyplot as ply 
#from scipy.stats import linregress 

class MyFileDropTarget(wx.FileDropTarget):

    def __init__(self, window): 
     wx.FileDropTarget.__init__(self) 
     self.window = window 

    #---------------------------------------------------------------------- 
    def OnDropFiles(self, x, y, filenames): 
     self.window.SetInsertionPointEnd(y) 
     #self.window.updateText("\n%d file(s) dropped at %d,%d:\n" % 
     #     (len(filenames), x, y), y) 
     for filepath in filenames: 
      self.window.updateText(filepath + '\n', y) 


class MyPanel(wx.Panel): 

    def __init__(self, parent): 
     wx.Panel.__init__(self, parent) 
     file_drop_target = MyFileDropTarget(self) 
     file_drop_target2 = MyFileDropTarget(self) 
     file_drop_target3 = MyFileDropTarget(self) 

     #Create some sizers 
     mainSizer = wx.BoxSizer(wx.VERTICAL) 
     grid = wx.GridBagSizer(hgap=5, vgap=5)

Обратите внимание, что вы можете использовать цикл для создания этих ярлыков и текстовых виджетов.

Answer 2

Майк, ваше решение действительно помогло мне поблагодарить вас. Хотя он решил проблему с закрытием окна, это вызвало проблему с возможностью ввода файлов и отображения их имен. Я изменил код, который вы предоставили, чтобы он работал для меня, и публикую его здесь, если у кого-то есть проблема, подобная этому. Это не самое элегантное решение, но оно работает. Еще раз спасибо.
