</warning>
<para>The <link

provides a convenient way to create and manage menus, menubars and option
menus from a data description. The data description is a tuple or list
containing a list of entry tuples that each describe an individual menu,
menuitem, etc. Each entry tuple may contain the following entry fields
though only the path must be specified; the other fields are
optional:</para>
<itemizedlist>
<listitem>
<simpara>A path that defines the logical position of the menu or
menuitem in the menu hierarchy. a path is similar to a file path in that it
starts with a slash (/) character and all components are joined by a slash
(/) character. The last component may have an underscore that indicates that
the following character is to be used as the accelerator mnemonic.</simpara>
</listitem>
<listitem>
<simpara>An accelerator that defines a key sequence that will
activate the menuitem. The key sequence is a set of zero or more modifiers
followed by a single key. The modifier keys are:</simpara>
<variablelist>
<varlistentry>
<term>"<alt>"</term>
<listitem>
<simpara><keycap>Alt-L</keycap>or
<keycap>Alt-R</keycap></simpara>

<keycap>Shift-R</keycap></simpara>
</listitem>
</varlistentry>
</variablelist>
</listitem>
<listitem>
<simpara>A callback function or method that will be invoked when the
menu item is activated or the accelerator key sequence is pressed. The
callback function is defined as either:</simpara>
<programlisting>
def callback(callback_data, callback_action, widget)
def callback(callback_action, widget)
</programlisting>
<simpara>where <parameter>callback_action</parameter> is the
callback action defined below, <parameter>callback_data</parameter> is the
data passed with the <link
linkend="method-gtkitemfactory--create-items"><methodname>create_items</methodname>()</link>
method and <parameter>widget</parameter> is the menuitem widget. The second
definition must be used if no <parameter>callback_data</parameter> argument
is specified by the call to <link
linkend="method-gtkitemfactory--create-items"><methodname>create_items</methodname>()</link>.</simpara>
</listitem>
<listitem>

value.</simpara>
