<h1>Form Input</h1>
The Form interface is a convenient way to create dialogs. It is done by
adding different widgets to a form, using a collection of Scheme
functions. Each input widget has a name and a value, and the results
are returned as an associative list.
<p>
Example: <a href="../../xcommon/form.scm">form.scm</a>
<p>
<dl>
<dt><b>(form-begin)</b>
<dd>Start a new form
<dt><b>(form-label <i>label</i>)</b>
<dd>Add a label to the form
<dt><b>(form-text <i>name</i>)</b>
<dd>Add a text entry field to the form
<dt><b>(form-withprompt <i>prompt value width</i>)</b>
<dd>Create a label followed by a text field of a specified width
<dt><b>(form-record <i>name name ...</i>)</b>
<dd>Create a form with one label and one text field per line
<dt><b>(form-menu <i>name</i>)</b>
<dd>Add a pull-down menu
<dt><b>(form-menuentry <i>text</i>)</b>
<dd>Add one entry to the menu
<dt><b>(form-okbutton <i>label</i>)</b>
<dd>Add a button which pops down the form, collects
the values and returns them
<dt><b>(form-cancelbutton <i>label</i>)</b>
<dd>Add a button which pops down the form, discards the values
and returns the empty list
<dt><b>(form-property <i>name value</i>)</b>
<dd>Changes an X property of the most recently added widget
<dt><b>(form-properties <i>name value name value ...</i>)</b>
<dd>Changes several properties in a single call
<dt><b>(form-newline)</b>
<dd>Add the next widget below the last one, rather than to the right
<dt><b>(form-end)</b>
<dd>Pop up the form, wait for the user to do something,
return the results
