  14 As far as I know (I may be wrong), a wx.Panel is "composed" by a GtkPizza
  15 as a child of GtkScrolledWindow. GtkPizza is a custom widget created for
  16 wxGTK.
  17 
  18 WebKitGTK+ - the webkit port for GTK+ that has python bindings - wants a
  19 GtkScrolledWindow as parent.
  20 
  21 So all we need to embed webkit in wxGTK is find the wx.Panel's
  22 GtkScrolledWindow.
  23 This is acomplished using pygtk that is present in major distro's by
  24 default, at least those that use gnome as its main desktop environment.
  25 
  26 A last note is that for get a handle of a window in X, the window must be
  27 "realized" first, in other words, must already exists. So we must Show
  28 the wx.Frame before use this WKHtmlWindow class.
