{- |
Creates a new 'GI.Gio.Objects.MenuItem.MenuItem' representing a section.

This is a convenience API around 'GI.Gio.Objects.MenuItem.menuItemNew' and
'GI.Gio.Objects.MenuItem.menuItemSetSection'.

The effect of having one menu appear as a section of another is
exactly as it sounds: the items from /@section@/ become a direct part of
the menu that /@menuItem@/ is added to.

Visual separation is typically displayed between two non-empty
sections.  If /@label@/ is non-'Nothing' then it will be encorporated into
this visual indication.  This allows for labeled subsections of a
menu.

As a simple example, consider a typical \"Edit\" menu from a simple
program.  It probably contains an \"Undo\" and \"Redo\" item, followed by
a separator, followed by \"Cut\", \"Copy\" and \"Paste\".

This would be accomplished by creating three 'GI.Gio.Objects.Menu.Menu' instances.  The
first would be populated with the \"Undo\" and \"Redo\" items, and the
second with the \"Cut\", \"Copy\" and \"Paste\" items.  The first and
second menus would then be added as submenus of the third.  In XML
format, this would look something like the following:
>
><menu id='edit-menu'>
>  <section>
>    <item label='Undo'/>
>    <item label='Redo'/>
>  </section>
>  <section>
>    <item label='Cut'/>
>    <item label='Copy'/>
>    <item label='Paste'/>
>  </section>
></menu>


The following example is exactly equivalent.  It is more illustrative
of the exact relationship between the menus and items (keeping in
mind that the \'link\' element defines a new menu that is linked to the
containing one).  The style of the second example is more verbose and
difficult to read (and therefore not recommended except for the
purpose of understanding what is really going on).
>
><menu id='edit-menu'>
>  <item>
>    <link name='section'>
>      <item label='Undo'/>
>      <item label='Redo'/>
>    </link>
>  </item>
>  <item>
>    <link name='section'>
>      <item label='Cut'/>
>      <item label='Copy'/>
>      <item label='Paste'/>
>    </link>
>  </item>
></menu>

Sets or unsets the \"action\" and \"target\" attributes of /@menuItem@/.

If /@action@/ is 'Nothing' then both the \"action\" and \"target\" attributes
are unset (and /@targetValue@/ is ignored).

If /@action@/ is non-'Nothing' then the \"action\" attribute is set.  The
\"target\" attribute is then set to the value of /@targetValue@/ if it is
non-'Nothing' or unset otherwise.

Normal menu items (ie: not submenu, section or other custom item
types) are expected to have the \"action\" attribute set to identify
the action that they are associated with.  The state type of the
action help to determine the disposition of the menu item.  See
'GI.Gio.Interfaces.Action.Action' and 'GI.Gio.Interfaces.ActionGroup.ActionGroup' for an overview of actions.

In general, clicking on the menu item will result in activation of
the named action with the \"target\" attribute given as the parameter
to the action invocation.  If the \"target\" attribute is not set then
the action is invoked with no parameter.

If the action has no state then the menu item is usually drawn as a
plain menu item (ie: with no additional decoration).

If the action has a boolean state then the menu item is usually drawn
as a toggle menu item (ie: with a checkmark or equivalent
indication).  The item should be marked as \'toggled\' or \'checked\'
when the boolean state is 'True'.

If the action has a string state then the menu item is usually drawn
as a radio menu item (ie: with a radio bullet or equivalent
indication).  The item should be marked as \'selected\' when the string
state is equal to the value of the /@target@/ property.

See @/g_menu_item_set_action_and_target()/@ or
'GI.Gio.Objects.MenuItem.menuItemSetDetailedAction' for two equivalent calls that are
probably more convenient for most uses.

can be one of the standard attribute names 'GI.Gio.Constants.MENU_ATTRIBUTE_LABEL',
'GI.Gio.Constants.MENU_ATTRIBUTE_ACTION', 'GI.Gio.Constants.MENU_ATTRIBUTE_TARGET', or a custom

must not end with a \'-\', and must not contain consecutive dashes.

must consist only of lowercase
ASCII characters, digits and \'-\'.

If /@value@/ is non-'Nothing' then it is used as the new value for the
attribute.  If /@value@/ is 'Nothing' then the attribute is unset. If
the /@value@/ 'GVariant' is floating, it is consumed.
