wxPython：如何使用多个窗口？

Question

我正在制作一个程序，为您提供可供选择的艺术家列表，当您点击艺术家时，它会打开一个新窗口，并为您提供他们的绘画选择。但是，当我尝试这样做时，新窗口上没有任何反应。我不能在它上面放任何按钮，甚至静态文本都不起作用，它在父窗口上工作得很好，但在子窗口上却不行。我错过了什么或者我是否需要完全做其他事情？这是我的代码：

import webbrowser
import sqlite3
import wx

conn = sqlite3.connect("dbPaintings.db")
c = conn.cursor()
c.execute("CREATE TABLE IF NOT EXISTS tblPaintings(Artist TEXT, PaintingName TEXT, Link TEXT)")
path = 'Artists Paintings.txt'

def insertingPaintings():
    line = ''
    filePaintings=open(path,'r')
    for x in range(15):
        arrPaintings = filePaintings.readline().split(",")
        if len(arrPaintings) == 3:
            strArtist = arrPaintings[0]
            strPainting = arrPaintings[1]
            strLink = arrPaintings[2]
            strLink = strLink.split("\\")[0]
            c.execute("INSERT INTO tblPaintings(Artist, PaintingName, Link) VALUES(:ArtistName, :Painting, :Url)", {'ArtistName':strArtist,'Painting':strPainting,'Url':strLink})
            conn.commit()
#insertingPaintings()

Answer 1

请注意，如果您发布了一小段代码，可以由任何人运行，而不需要您的数据库和jpg等，这将更容易

在

class ArtFrame(wx.Frame):
def  __init__(self, keyID, title, parent):
    wx.Frame.__init__(self,parent=parent,title=title,size=(800,600))
    panel = wx.Panel(self)
    wx.StaticText(panel,-1,"Working",(566,345))
    self.SetBackgroundColour('white')
    if keyID=='Auguste Renoir':
        self.AugusteRenoirWork()
def AugusteRenoirWork(self):
    UmbrellasButtonImage = wx.Image('The Umbrellas.jpg',wx.BITMAP_TYPE_JPEG).ConvertToBitmap()
    UmbrellasButton = wx.BitmapButton(wx.Panel(self),-1,UmbrellasButtonImage,pos=(200,200),size=(200,250))

当创建wx.BitmapButton时，它有一个新面板作为其父wx.Panel（self），而是使用在init中创建的面板

这样的事情

class ArtFrame(wx.Frame):
def  __init__(self, keyID, title, parent):
    wx.Frame.__init__(self,parent=parent,title=title,size=(800,600))
    self.panel = wx.Panel(self)
    wx.StaticText(self.panel,-1,"Working",(566,345))
    self.SetBackgroundColour('white')
    if keyID=='Auguste Renoir':
        self.AugusteRenoirWork()
def AugusteRenoirWork(self):
    UmbrellasButtonImage = wx.Image('The Umbrellas.jpg',wx.BITMAP_TYPE_JPEG).ConvertToBitmap()
    UmbrellasButton = wx.BitmapButton(self.panel,-1,UmbrellasButtonImage,pos=(200,200),size=(200,250))
