\section{Standard Module \sectcode{panel}}
|
|
\label{module-panel}
|
|
\stmodindex{panel}
|
|
|
|
\strong{Please note:} The FORMS library, to which the \code{fl} module described
|
|
above interfaces, is a simpler and more accessible user interface
|
|
library for use with GL than the Panel Module (besides also being by a
|
|
Dutch author).
|
|
|
|
This module should be used instead of the built-in module
|
|
\code{pnl}
|
|
to interface with the
|
|
\emph{Panel Library}.
|
|
|
|
The module is too large to document here in its entirety.
|
|
One interesting function:
|
|
|
|
\renewcommand{\indexsubitem}{(in module panel)}
|
|
\begin{funcdesc}{defpanellist}{filename}
|
|
Parses a panel description file containing S-expressions written by the
|
|
\emph{Panel Editor}
|
|
that accompanies the Panel Library and creates the described panels.
|
|
It returns a list of panel objects.
|
|
\end{funcdesc}
|
|
|
|
\strong{Warning:}
|
|
the Python interpreter will dump core if you don't create a GL window
|
|
before calling
|
|
\code{panel.mkpanel()}
|
|
or
|
|
\code{panel.defpanellist()}.
|
|
|
|
\section{Standard Module \sectcode{panelparser}}
|
|
\stmodindex{panelparser}
|
|
|
|
This module defines a self-contained parser for S-expressions as output
|
|
by the Panel Editor (which is written in Scheme so it can't help writing
|
|
S-expressions).
|
|
The relevant function is
|
|
\code{panelparser.parse_file(\var{file})}
|
|
which has a file object (not a filename!) as argument and returns a list
|
|
of parsed S-expressions.
|
|
Each S-expression is converted into a Python list, with atoms converted
|
|
to Python strings and sub-expressions (recursively) to Python lists.
|
|
For more details, read the module file.
|
|
% XXXXJH should be funcdesc, I think
|
|
|
|
\section{Built-in Module \sectcode{pnl}}
|
|
\bimodindex{pnl}
|
|
|
|
This module provides access to the
|
|
\emph{Panel Library}
|
|
built by NASA Ames (to get it, send e-mail to
|
|
{\tt panel-request@nas.nasa.gov}).
|
|
All access to it should be done through the standard module
|
|
\code{panel},
|
|
which transparantly exports most functions from
|
|
\code{pnl}
|
|
but redefines
|
|
\code{pnl.dopanel()}.
|
|
|
|
\strong{Warning:}
|
|
the Python interpreter will dump core if you don't create a GL window
|
|
before calling
|
|
\code{pnl.mkpanel()}.
|
|
|
|
The module is too large to document here in its entirety.
