<title>Description</title>
<para>
  This will add a popup-menu to a non <link linkend="GTK-WIDGET-NO-WINDOW">GTK_WIDGET_NO_WINDOW</link>() widget.  It
  also has the ability to add "cut", "copy" and "paste" to <link linkend="GtkEditable">GtkEditable</link>
  widgets if needed.  It is important to not run this on a widget
  without a window, as doing so can lead to stuck pointer grabs.  This
  function should be used where possible everywhere else.

<para>
This creates a popup menu on <parameter>widget</parameter> with one entry.  The menu, invoked by
pressing button three on the widget, will have one entry entitled: "Help with
this."  Selecting this entry will bring up a tooltip with the help variable
as its text.  In addition, if the widget is a descendent of <link linkend="GtkEditable">GtkEditable</link>, it
will add "cut", "copy", and "paste" to the menu.  If <parameter>help</parameter> is NULL, then it
will &lt;emphasis&gt;just&lt;/emphasis&gt; add the "cut", "copy", and "paste".  Finally,
if <parameter>menuinfo</parameter> is non-NULL, it will append the menu defined by it on the end of
the popup menu, with <parameter>user_data</parameter> passed to the callbacks.  This function
currently only works on non <link linkend="GTK-WIDGET-NO-WINDOW">GTK_WIDGET_NO_WINDOW</link>() widgets (ie. it only
works on widgets with windows.)  If you would actually like a handle to the
popup menu, call <link linkend="gnome-popup-menu-get">gnome_popup_menu_get</link>() as normal.</para>
