使用wx.EVT_MOVE拖放圖像

我想用拖放圖像編寫腳本。我上傳了2張圖片（.jpg）並嘗試在面板上拖動圖片。當我在面板上拖動firstImage時 - 一切看起來都不錯。但是當我在面板上拖動secondImage（特別是當secondImage與firstImage聯繫時）發生了一個錯誤。位於firstImage內容下的secondImage的內容。我怎麼做，當我拖動secondImage，其內容位於firstImage的內容？謝謝。使用wx.EVT_MOVE拖放圖像

script.py

import wx 
import wx.lib.buttons as buttons 

class Main(wx.Frame): 
    def __init__(self, parent, title): 
     wx.Frame.__init__(self, parent, id=-1, title=title, size=(300, 300)) 

     self.panel = wx.Panel(self, wx.ID_ANY, wx.DefaultPosition, size=(300, 300)) 

     firstImage = ButtonImage(self, self.panel, r'.\image_wtf\1.jpg', (20,20)) 
     secondImage = ButtonImage(self, self.panel, r'.\image_wtf\2.jpg', (20, 135)) 

     self.Layout() 

class ButtonImage(): 
    def __init__(self, parent, panel, nameImage, pos): 
     self.panel = panel 

     self.bmp = wx.Bitmap(nameImage, wx.BITMAP_TYPE_ANY) 

     ### search for a piece of the maximum position (limit boundary)

      self.bmapBtn.Refresh() 

app = wx.PySimpleApp() 
frame = Main(None, u"Game") 
frame.Show() 
app.MainLoop()

你可以使用加註（）對提高窗口到窗口層次結構的頂部。

def MoveButton(): 
    ................. 
    ................. 
    self.bmapBtn.Raise() 
    self.bmapBtn.Refresh()
