class Frame(wx.Frame):
   def __init__(self, parent):
       wx.Frame.__init__(self, parent, -1)

       self.panel = wx.Panel(self, -1)
       sizer = wx.BoxSizer(wx.VERTICAL)

       self.btn = wx.Button(self.panel, -1, "drop here")
       sizer.Add(self.btn, 1, wx.EXPAND)

       self.panel.SetAutoLayout(True)
       self.panel.SetSizer(sizer)

       dt = DropTarget(self.btn)
       self.btn.SetDropTarget(dt)

class DropTarget(wx.PyDropTarget):
   def __init__(self, window):
       wx.PyDropTarget.__init__(self)
       #self.do = wx.TextDataObject()
       self.do = wx.CustomDataObject(wx.DataFormat(wx.DF_TEXT))
       self.SetDataObject(self.do)

   def OnEnter(self, x, y, d):
       print 'on enter'
       return d

       self.frame.Show(True)
       return True

app = App()
app.MainLoop()
