# Text editor supporting various formatting, intended for editing

class Wx::RichTextCtrl
# These three methods return the styles applicable at certain points
# in the document. However, the standard wx signature is to accept the
# value of some kind of TextAttr class that will hold the return as an
# argument. The return value is a boolean for success/failure. In
# Ruby, we only support returning the value as a RichTextAttr, and do
# so as a proper return value, having accepted a single argument
# specifying where to get the style from. If retrieval is not
# successful, raise an exception.
