60
61<P>
62Form objects (returned by <tt class="function">make_form()</tt> above) have the
63following methods. Each method corresponds to a C function whose
64name is prefixed with "<tt class="samp">fl_</tt>"; and whose first argument is a form
65pointer; please refer to the official FORMS documentation for
66descriptions.
67
68<P>
69All the <tt class="method">add_*()</tt> methods return a Python object representing
70the FORMS object. Methods of FORMS objects are described below. Most
71kinds of FORMS object also have some methods specific to that kind;
72these methods are listed here.
