After initialization the methods GetFileTypeFromMimeType() and GetFileTypeFromExtension() may be called: they will return a wx.FileType object which may be further queried for file description, icon and other attributes. A global instance of wx.MimeTypesManager is always available as wx.TheMimeTypesManager. It is recommended to use this instance instead of creating your own because gathering MIME information may take quite a long on Unix systems. This demo shows how to use wx.TheMimeTypesManager to list all known MIME types and retrieve that information as a wx.FileType from either an extension or MIME type. For further information please consult the wxWindows documentation for wx.MimeTypesManager and wx.FileType.
