Might want to comment that size is taken from the first image in the list / see
spec.

+    for x, y, filename in self.imglist:
+      img = wx.Image(filename, wx.BITMAP_TYPE_ANY)
+      if (not done_first):
+        size = img.GetSize()
+        self.SetMinSize(size)
+        self.SetSize(size)
+        self.Fit()
+        w,h = self.parent.GetBestSize()
+        self.parent.SetDimensions(-1, -1, w, h, wx.SIZE_AUTO)
+        done_first = True
+      bmp = img.ConvertToBitmap()
+      dc.DrawBitmap(bmp, x, y)
+
+
+class Frame(wx.Frame):
+
+  def __init__(self, bmpblock=None, title=None):
+    wx.Frame.__init__(self, None, wx.ID_ANY, title=title)
+    self.CreateStatusBar()
+    self.SetStatusText(title)
+    self.Bind(wx.EVT_CLOSE, self.OnQuit)
+
+    # HEY: really?

Leftover comment? (line 51 too)

+    self.bmpblock = bmpblock
+    if self.bmpblock:
+      self.bmpblock.RegisterScreenDisplayObject(self)
+
+    # Is this enough?
+    self.p = MyPanel(self)

+  def OnQuit(self, event):
+    wx.GetApp().ExitMainLoop()
+
+  def DisplayScreen(self, name, imglist):
+    self.SetStatusText(name)
+    self.p.imglist = imglist
+    self.p.OnPaint()
