<div class="deprecated">
<p><span class="versionmodified">Deprecated since version 2.6: </span>The <a class="reference internal" href="#module-fl" title="fl: FORMS library for applications with graphical user interfaces. (deprecated) (IRIX)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">fl</span></code></a> module has been removed in Python 3.</p>
</div>
<p id="index-0">This module provides an interface to the FORMS Library by Mark Overmars. The
source for the library can be retrieved by anonymous FTP from host
<code class="docutils literal notranslate"><span class="pre">ftp.cs.ruu.nl</span></code>, directory <code class="file docutils literal notranslate"><span class="pre">SGI/FORMS</span></code>. It was last tested with version
2.0b.</p>
<p>Most functions are literal translations of their C equivalents, dropping the
initial <code class="docutils literal notranslate"><span class="pre">fl_</span></code> from their name. Constants used by the library are defined in
module <a class="reference internal" href="#module-FL" title="FL: Constants used with the fl module. (deprecated) (IRIX)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">FL</span></code></a> described below.</p>
<p>The creation of objects is a little different in Python than in C: instead of
the ‘current form’ maintained by the library to which new FORMS objects are
added, all functions that add a FORMS object to a form are methods of the Python
object representing the form. Consequently, there are no Python equivalents for
the C functions <code class="xref c c-func docutils literal notranslate"><span class="pre">fl_addto_form()</span></code> and <code class="xref c c-func docutils literal notranslate"><span class="pre">fl_end_form()</span></code>, and the
equivalent of <code class="xref c c-func docutils literal notranslate"><span class="pre">fl_bgn_form()</span></code> is called <a class="reference internal" href="#fl.make_form" title="fl.make_form"><code class="xref py py-func docutils literal notranslate"><span class="pre">fl.make_form()</span></code></a>.</p>
<p>Watch out for the somewhat confusing terminology: FORMS uses the word
<em class="dfn">object</em> for the buttons, sliders etc. that you can place in a form. In
Python, ‘object’ means any value. The Python interface to FORMS introduces two
new Python object types: form objects (representing an entire form) and FORMS
objects (representing one button, slider etc.). Hopefully this isn’t too
confusing.</p>
<p>There are no ‘free objects’ in the Python interface to FORMS, nor is there an
easy way to add object classes written in Python. The FORMS interface to GL
event handling is available, though, so you can mix FORMS with pure GL windows.</p>
<p><strong>Please note:</strong> importing <a class="reference internal" href="#module-fl" title="fl: FORMS library for applications with graphical user interfaces. (deprecated) (IRIX)"><code class="xref py py-mod docutils literal notranslate"><span class="pre">fl</span></code></a> implies a call to the GL function
<code class="xref c c-func docutils literal notranslate"><span class="pre">foreground()</span></code> and to the FORMS routine <code class="xref c c-func docutils literal notranslate"><span class="pre">fl_init()</span></code>.</p>
