从其他模块发出关闭wxpython框架的问题

Question

我正在制作一个简单的联系人编译器，目前使用三个模块：一个用于接收信息的person类，一个用于允许用户提交信息的newContact Frame类，另一个用于首页Frame类，列出联系人的姓名，并为用户提供编辑列表的选项。

我遇到的问题是当我在首页类中调用newContact类的main函数时，它不会退出MainLoop。即使我销毁了newContact窗口，并且两个程序在没有相互调用时正常关闭。这是相关的代码：

import wx
import person

contacts = []
names = []

class newContact(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(newContact, self).__init__(*args, **kwargs)

        self.basicWindow()
        self.Show()

    def basicWindow(self):

        panel = wx.Panel(self)

        vertical = wx.BoxSizer(wx.VERTICAL)


        heading = wx.StaticText(panel, label = 'Create New Contact')
        vertical.Add(heading, flag = wx.LEFT | wx.TOP, border = 5)

        nameBox = wx.BoxSizer(wx.HORIZONTAL)
        nameText = wx.StaticText(panel, label = 'Name:')
        nameBox.Add(nameText)
        self.nameEntry = wx.TextCtrl(panel)

        nameBox.Add(self.nameEntry, proportion = 1, flag = wx.LEFT, border = 50)
        vertical.Add(nameBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        phoneBox = wx.BoxSizer(wx.HORIZONTAL)
        phoneText = wx.StaticText(panel, label = 'Number:')
        phoneBox.Add(phoneText)
        self.phoneEntry = wx.TextCtrl(panel)
        phoneBox.Add(self.phoneEntry, proportion = 1, flag = wx.LEFT, border = 38)
        vertical.Add(phoneBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        mailBox = wx.BoxSizer(wx.HORIZONTAL)
        mailText = wx.StaticText(panel, label = 'Email:')
        mailBox.Add(mailText)
        self.mailEntry = wx.TextCtrl(panel)
        mailBox.Add(self.mailEntry, proportion = 1, flag = wx.LEFT, border = 53)
        vertical.Add(mailBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        submit = wx.Button(panel, label = 'Submit', size = (70,30))
        vertical.Add(submit, flag = wx.ALIGN_RIGHT | wx.TOP | wx.RIGHT, border = 10)

        self.Bind(wx.EVT_BUTTON, self.registerData)

        panel.SetSizer(vertical)


    def registerData(self, e):
        name = self.nameEntry.GetValue()
        name = name.title()
        while True:
            try:
                number = int(self.phoneEntry.GetValue())
                break
            except ValueError:
                number = 'a'
                break
        email = self.mailEntry.GetValue()

        contact = person.Person(name, number, email)
        names.append(name)
        contacts.append(contact)

        print('hello')

        self.quit()

    def quit(self):
        self.Destroy()


def main():
    app = wx.App()
    newContact(None, title = 'New Contact', size = (405, 200), style= wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX)
    app.MainLoop()

import wx
import newContact

class Front(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(Front, self).__init__(*args, **kwargs)

        self.interaction()

    def interaction(self):

        panel = wx.Panel(self)

        wholeGrid = wx.BoxSizer(wx.VERTICAL)

        mainBox = wx.BoxSizer(wx.HORIZONTAL)

        title = wx.StaticText(panel, label = '  Contact List')
        wholeGrid.Add(title, flag = wx.TOP | wx.LEFT, border = 10)

        self.contactList = wx.ListBox(panel)

        edit = wx.Button(panel, id = wx.ID_EDIT, label = 'Edit', size = (100,30))
        buttonList.Add(edit, flag = wx.TOP, border = 5)
        delete = wx.Button(panel, id = wx.ID_DELETE, label = 'Delete', size = (100,30))
        buttonList.Add(delete, flag = wx.TOP, border = 5)
        mainBox.Add(buttonList, flag = wx.ALIGN_RIGHT | wx.TOP | wx.RIGHT, border = 10)

        wholeGrid.Add(mainBox, proportion = 1, flag = wx.EXPAND)

        panel.SetSizer(wholeGrid)

        self.Bind(wx.EVT_BUTTON, self.createNew, id = wx.ID_NEW)


        menu = wx.MenuBar()
        fileMenu = wx.Menu()
        fileMenu.Append(wx.ID_EXIT, 'Exit')
        menu.Append(fileMenu, 'File')
        self.SetMenuBar(menu)

        self.Show(True)

    def createNew(self, e):
        newContact.main()



def main():
    app = wx.App()
    Front(None, title = "Contacts", size = (405,600), style = wx.SYSTEM_MENU | wx.CLOSE_BOX | wx.CAPTION)
    app.MainLoop()

感谢您的帮助，我们也欢迎使用代码语法评论。

在我看来，你只是关闭了newContact框架，而不是顶级前框架。您应该可以在newContact的quit方法中执行以下操作：

import wx

class newContact(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(newContact, self).__init__(*args, **kwargs)

        self.basicWindow()
        self.Show()

    def basicWindow(self):

        panel = wx.Panel(self)

        vertical = wx.BoxSizer(wx.VERTICAL)


        heading = wx.StaticText(panel, label = 'Create New Contact')
        vertical.Add(heading, flag = wx.LEFT | wx.TOP, border = 5)

        nameBox = wx.BoxSizer(wx.HORIZONTAL)
        nameText = wx.StaticText(panel, label = 'Name:')
        nameBox.Add(nameText)
        self.nameEntry = wx.TextCtrl(panel)

        nameBox.Add(self.nameEntry, proportion = 1, flag = wx.LEFT, border = 50)
        vertical.Add(nameBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        phoneBox = wx.BoxSizer(wx.HORIZONTAL)
        phoneText = wx.StaticText(panel, label = 'Number:')
        phoneBox.Add(phoneText)
        self.phoneEntry = wx.TextCtrl(panel)
        phoneBox.Add(self.phoneEntry, proportion = 1, flag = wx.LEFT, border = 38)
        vertical.Add(phoneBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        mailBox = wx.BoxSizer(wx.HORIZONTAL)
        mailText = wx.StaticText(panel, label = 'Email:')
        mailBox.Add(mailText)
        self.mailEntry = wx.TextCtrl(panel)
        mailBox.Add(self.mailEntry, proportion = 1, flag = wx.LEFT, border = 53)
        vertical.Add(mailBox, flag = wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT, border = 10)

        submit = wx.Button(panel, label = 'Submit', size = (70,30))
        vertical.Add(submit, flag = wx.ALIGN_RIGHT | wx.TOP | wx.RIGHT, border = 10)

        self.Bind(wx.EVT_BUTTON, self.registerData)

        panel.SetSizer(vertical)


    def registerData(self, e):
        #name = self.nameEntry.GetValue()
        #name = name.title()
        #while True:
            #try:
                #number = int(self.phoneEntry.GetValue())
                #break
            #except ValueError:
                #number = 'a'
                #break
        #email = self.mailEntry.GetValue()

        #contact = person.Person(name, number, email)
        #names.append(name)
        #contacts.append(contact)

        self.quit()

    def quit(self):
        parent = self.GetParent()
        parent.Close()


class Front(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(Front, self).__init__(*args, **kwargs)

        self.interaction()

    def interaction(self):

        panel = wx.Panel(self)

        wholeGrid = wx.BoxSizer(wx.VERTICAL)

        mainBox = wx.BoxSizer(wx.HORIZONTAL)

        title = wx.StaticText(panel, label = '  Contact List')
        wholeGrid.Add(title, flag = wx.TOP | wx.LEFT, border = 10)

        self.contactList = wx.ListBox(panel)
        mainBox.Add(self.contactList, proportion = 1, flag = wx.EXPAND | wx.ALL, border = 10)

        buttonList = wx.BoxSizer(wx.VERTICAL)
        new = wx.Button(panel, id = wx.ID_NEW, label = 'New', size = (100,30))
        buttonList.Add(new)
        edit = wx.Button(panel, id = wx.ID_EDIT, label = 'Edit', size = (100,30))
        buttonList.Add(edit, flag = wx.TOP, border = 5)
        delete = wx.Button(panel, id = wx.ID_DELETE, label = 'Delete', size = (100,30))
        buttonList.Add(delete, flag = wx.TOP, border = 5)
        mainBox.Add(buttonList, flag = wx.ALIGN_RIGHT | wx.TOP | wx.RIGHT, border = 10)

        wholeGrid.Add(mainBox, proportion = 1, flag = wx.EXPAND)

        panel.SetSizer(wholeGrid)

        self.Bind(wx.EVT_BUTTON, self.createNew, id = wx.ID_NEW)


        menu = wx.MenuBar()
        fileMenu = wx.Menu()
        fileMenu.Append(wx.ID_EXIT, 'Exit')
        menu.Append(fileMenu, 'File')
        self.SetMenuBar(menu)

        self.Show(True)

    def createNew(self, e):
        other_frame = newContact(self)


#----------------------------------------------------------------------
if __name__ == "__main__":
    app = wx.App() 
    Front(None, title = "Contacts", 
          size = (405,600), style = wx.SYSTEM_MENU | wx.CLOSE_BOX | wx.CAPTION) 
    app.MainLoop()

稍微更改了代码，使其无需保存两个文件即可运行。您不应该像在 createNew 方法中那样直接调用类，所以我更改了...还要注意，无论如何都没有 main 方法。 / p>
