-wxTextAttr represents the character and paragraph attributes, or style, for a range of text in a\rtfsp
-\helpref{wxTextCtrl}{wxtextctrl}.
-
-When setting up a wxTextAttr object, pass a bitlist mask to SetFlags to indicate
-which style elements should be changed. As a convenience, when you call a
-setter such as SetFont, the relevant bit will be set.

-\texttt{wxTextPos} is the type containing the index of a position in a text
-control. \texttt{wxTextCoord} contains the index of a column or a row in the
-control.
-
-Note that although both of these types should probably have been unsigned, due
-to backwards compatibility reasons, are defined as \texttt{long} currently.
-Their use (instead of plain \texttt{long}) is still encouraged as it makes the
-code more readable.

Loads and displays the named file, if it exists.
