  App(redirect = False).MainLoop()

一点点的解释：

class App与App().MainLoop()是固定写法，在class App下有一个def OnInit方法来初始化主的Frame，将其居中并且Show()出来，没什么好说的，主要看一下Frame的定义

这个小工具使用的是boxSizer来布局，为了简单我只使用了一个boxSizer，将里面的所有控件采用VERTICAL(垂直)的方式来布局，如果想要将MD5与后面的文本框放在同一行，那么就需要添加一个水平的boxSizer，然后那将这个水平的boxSizer再放入主的boxSizer

boxSizer = wx.BoxSizer(wx.VERTICAL) #初始化一个垂直的boxSizer，也是整个框架的主Sizer

self.panel = wx.Panel(self) #初始化一个panel，这个panel是放了放之后的控件的

filepath = wx.StaticText(self.panel,-1,"FileDir(请将文件拖到本对话框中)") 
filetext = wx.TextCtrl(self.panel,-1,"",size=(350,20)) 
md5st = wx.StaticText(self.panel,-1,"MD5") 
md5tx = wx.TextCtrl(self.panel,-1,size=(250,20)) 
filesizest = wx.StaticText(self.panel,-1,'FileSize') 
filesizetx = wx.TextCtrl(self.panel,-1,size=(250,20))

boxSizer.Add(filepath,0,wx.EXPAND|wx.LEFT|wx.TOP,border=10) 

boxSizer.Add((-1,20)) #这个是添加一个空距离，距离上20px

dropTarget = FileDropTarget(filetext,md5tx,filesizetx) 
self.panel.SetDropTarget( dropTarget )
