这是我在 Boa Constructor 中的第一个应用程序，也是我第一次使用 wxPython。

#Boa:Frame:Frame1

import wx

choiceList = ['DAR', 'Impex', 'Endon', 'Astro', 'Ansell', 'Other']

def create(parent):
    return Frame1(parent)

[wxID_FRAME1, wxID_FRAME1BUTTONSELECTDIR, wxID_FRAME1BUTTONSELECTFILE, 
 wxID_FRAME1CHOICESUPPLIER, 
] = [wx.NewId() for _init_ctrls in range(4)]

class Frame1(wx.Frame):
    def _init_ctrls(self, prnt):
        # generated method, don't edit
        wx.Frame.__init__(self, id=wxID_FRAME1, name='', parent=prnt,
              pos=wx.Point(517, 20), size=wx.Size(400, 492),
              style=wx.DEFAULT_FRAME_STYLE, title='Frame1')
        self.SetClientSize(wx.Size(392, 458))

        self.choiceSupplier = wx.Choice(choices=choiceList, id=wxID_FRAME1CHOICESUPPLIER,
              name=u'choiceSupplier', parent=self, pos=wx.Point(48, 176),
              size=wx.Size(120, 21), style=0)
        self.choiceSupplier.Bind(wx.EVT_CHOICE, self.OnChoiceSupplierChoice,
              id=wxID_FRAME1CHOICESUPPLIER)

    def __init__(self, parent):
        self._init_ctrls(parent)

    def OnChoiceSupplierChoice(self, event):
        supplier = choiceList[self.choiceSupplier.GetSelection()]
        print supplier

单击运行应用程序时，我的代码运行良好。但是，当我尝试在设计器中对其进行编辑时，出现错误：

在寻找其他与 boa-constructor 相关的东西时偶然发现了这个问题，如果在这里回答有点死的帖子被认为是失礼，我很抱歉，我是新来的。

无论如何，我最好的猜测是你自己弄乱了 _init_ctrls 即使有“不要编辑”的评论。自己试过几次，蟒蛇处理得不太好。改变后

self.choiceSupplier = wx.Choice(choices=choiceList

至

self.choiceSupplier = wx.Choice(choices=''

您可以再次输入设计器，并且能够拥有并填充 wx.Choice 项目，我将列表移入init：

#Boa:Frame:Frame1

import wx

def create(parent):
    return Frame1(parent)

[wxID_FRAME1, wxID_FRAME1CHOICESUPPLIER, 
] = [wx.NewId() for _init_ctrls in range(2)]

class Frame1(wx.Frame):
    def _init_ctrls(self, prnt):
        # generated method, don't edit
        wx.Frame.__init__(self, id=wxID_FRAME1, name='', parent=prnt,
              pos=wx.Point(517, 20), size=wx.Size(408, 496),
              style=wx.DEFAULT_FRAME_STYLE, title='Frame1')
        self.SetClientSize(wx.Size(392, 458))

        self.choiceSupplier = wx.Choice(choices=self.choiceList,
              id=wxID_FRAME1CHOICESUPPLIER, name=u'choiceSupplier', parent=self,
              pos=wx.Point(0, 0), size=wx.Size(392, 21), style=0)
        self.choiceSupplier.Bind(wx.EVT_CHOICE, self.OnChoiceSupplierChoice,
              id=wxID_FRAME1CHOICESUPPLIER)

    def __init__(self, parent):
        self.choiceList = ['DAR', 'Impex', 'Endon', 'Astro', 'Ansell', 'Other']
        self._init_ctrls(parent)

    def OnChoiceSupplierChoice(self, event):
        supplier = choiceList[self.choiceSupplier.GetSelection()]
        print supplier

if __name__ == '__main__':
    application = wx.PySimpleApp()
    someFrame = Frame1(None)
    someFrame.Show()
    application.MainLoop()

问题可能是设计器会话如何分析文件，错过了类外部的列表。
