title: How to change wx.Panel background color on MouseOver?
body: <p>this code:</p>
  
  <pre><code>import wx
  
  app = None
  
  class Plugin(wx.Panel):
      def __init__(self, parent, *args, **kwargs):
          wx.Panel.__init__(self, parent, *args, **kwargs)
          self.SetBackgroundColour((11, 11, 11))
          self.name = "plugin"
  
          self.Bind(wx.EVT_ENTER_WINDOW, self.onMouseOver)
          self.Bind(wx.EVT_LEAVE_WINDOW, self.onMouseLeave)
  
          wx.EVT_ENTER_WINDOW(self, self.onMouseOver)
          wx.EVT_LEAVE_WINDOW(self, self.onMouseLeave)
  
      def onMouseOver(self, event):
          self.SetBackgroundColor((179, 179, 179))
          self.Refresh()
  
      def onMouseLeave(self, event):
          self.SetBackgroundColor((11, 11, 11))
          self.Refresh()
  
      def OnClose(self, event):
          self.Close()
          app.Destroy()
  
      def name():
          print self.name
  
  
  app = wx.App()
  frame = wx.Frame(None, -1, size=(480, 380))
  Plugin(frame)
  frame.Show(True)
  app.MainLoop()
  </code></pre>
  
  <p>gives me the error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "C:\.... ... ....\plugin.py", line 18, in onMouseOver
      self.SetBackgroundColor((179, 179, 179))
  AttributeError: 'Plugin' object has no attribute 'SetBackgroundColor'
  </code></pre>
  
  <p>What am I doing wrong?
  P.S.: I need to have this class as a wx.Panel!</p>
  
  <p>Thanks in advance</p>
