<para>Now that we've shown you the hard way, here's how you do it using the
gtk_item_factory calls.</para>
<para>ItemFactory creates a menu out of an array of ItemFactory entries. This
means you can define your menu in its simplest form and then create the
menu/menubar widgets with a minimum of function calls.</para>
<!-- ----------------------------------------------------------------- -->
<sect2 id="sec-ItemFactoryEntries">
<title>ItemFactory entries</title>
<para>At the core of ItemFactory is the ItemFactoryEntry. This structure defines
one menu item, and when an array of these entries is defined a whole
menu is formed. The ItemFactory entry struct definition looks like this:</para>
<programlisting role="C">
struct _GtkItemFactoryEntry
{
gchar *path;
gchar *accelerator;
GtkItemFactoryCallback callback;
guint callback_action;
gchar *item_type;
};
</programlisting>
<para>Each field defines part of the menu item.</para>
<para><literal>*path</literal> is a string which defines both the name and the
path of a menu item, for example, "/File/Open" would be the name of a menu
item which would come under the ItemFactory entry with path "/File". Note however
that "/File/Open" would be displayed in the File menu as "Open". Also note
since the forward slashes are used to define the path of the menu,
they cannot be used as part of the name. A letter preceded by an underscore
indicates an accelerator (shortcut) key once the menu is open.</para>
<para>
<literal>*accelerator</literal> is a string that indicates a key combination
that can be used as a shortcut to that menu item. The string can be made up
of either a single character, or a combination of modifier keys with a single
character. It is case insensitive.</para>
<para>The available modifier keys are:</para>
<programlisting role="C">
"&lt;ALT&gt; - alt
"&lt;CTL&gt;" or "&lt;CTRL&gt;" or "&lt;CONTROL&gt;" - control
"&lt;MOD1&gt;" to "&lt;MOD5&gt;" - modn
"&lt;SHFT&gt;" or "&lt;SHIFT&gt;" - shift
</programlisting>
<para>Examples:</para>
<programlisting role="C">
"&lt;ConTroL&gt;a"
"&lt;SHFT&gt;&lt;ALT&gt;&lt;CONTROL&gt;X"
</programlisting>
<para>
<literal>callback</literal> is the function that is called when the menu item
emits the "activate" signal. The form of the callback is described
in the <link linkend="sec-ItemFactoryCallback">Callback Description</link>
section.</para>
<para>
The value of <literal>callback_action</literal> is passed to the callback
function. It also affects the function prototype, as shown
in the <link linkend="sec-ItemFactoryCallback">Callback Description</link>
section.</para>
<para>
<literal>item_type</literal> is a string that defines what type of widget is
packed into the menu items container. It can be:</para>
<programlisting role="C">
NULL or "" or "&lt;Item&gt;" - create a simple item
"&lt;Title&gt;" - create a title item
"&lt;CheckItem&gt;" - create a check item
"&lt;ToggleItem&gt;" - create a toggle item
"&lt;RadioItem&gt;" - create a (root) radio item
"Path" - create a sister radio item
"&lt;Tearoff&gt;" - create a tearoff
"&lt;Separator&gt;" - create a separator
"&lt;Branch&gt;" - create an item to hold submenus (optional)
"&lt;LastBranch&gt;" - create a right justified branch
</programlisting>
<para>Note that &lt;LastBranch&gt; is only useful for one submenu of
a menubar.</para>

<sect3 id="sec-ItemFactoryCallback">
<title>Callback Description</title>
<para>
The callback for an ItemFactory entry can take two forms. If
<literal>callback_action</literal> is zero, it is of the following
form:</para>
<programlisting role="C">
void callback(void)
</programlisting>
<para>otherwise it is of the form:</para>
<programlisting role="C">
void callback(gpointer callback_data,
guint callback_action,
GtkWidget *widget)
</programlisting>
<para>
<literal>callback_data</literal> is a pointer to an arbitrary piece of data and
is set during the call to gtk_item_factory_create_items().</para>
<para>
<literal>callback_action</literal> is the same value as
<literal>callback_action</literal> in the ItemFactory entry.</para>
<para>
<literal>*widget</literal> is a pointer to a menu item widget
(described in <link linkend="sec-ManualMenuCreation">Manual Menu Creation</link>).
</para>

<para>Creating a simple menu item:</para>
<programlisting role="C">
GtkItemFactoryEntry entry = {"/_File/_Open...", "&lt;CTRL&gt;O", print_hello,

</programlisting>
<para>This will define a new simple menu entry "/File/Open" (displayed as "Open"),
under the menu entry "/File". It has the accelerator (shortcut) control+'O'
that when clicked calls the function print_hello(). print_hello() is of
the form <literal>void print_hello(void)</literal> since the callback_action
field is zero. When displayed the 'O' in "Open" will be underlined and if the
menu item is visible on the screen pressing 'O' will activate the item. Note
that "File/_Open" could also have been used as the path instead of
"/_File/_Open".</para>

calls the function change_resolution() with the parameter

the form:</para>
<programlisting role="C">

<para><literal>entry2</literal> defines a radio button that belongs to the
radio group that entry1 belongs to. It calls the same function when toggled
but with the parameter <literal>callback_action</literal> equal to 2. Note that
the item_type of <literal>entry2</literal> is the path of entry1
<emphasis>without</emphasis> the accelerators ('_'). If another radio button was
required in the same group then it would be defined in the same way as
<literal>entry2</literal> was with its <literal>item_type</literal> again
equal to "/View/Low Resolution".</para>

<sect2 id="sec-ItemFactoryCreation">
<title>Creating an ItemFactory</title>
<para>An array of GtkItemFactoryEntry items defines a menu. Once this
array is defined then the item factory can be created. The function that
does this is:</para>
<programlisting role="C">
GtkItemFactory* gtk_item_factory_new( GtkType container_type,
const gchar *path,
GtkAccelGroup *accel_group );
</programlisting>
<para><literal>container_type</literal> can be one of:</para>
<programlisting role="C">
GTK_TYPE_MENU
GTK_TYPE_MENU_BAR
GTK_TYPE_OPTION_MENU
</programlisting>
<para><literal>container_type</literal> defines what type of menu
you want, so when you extract it later it is either a menu (for pop-ups
for instance), a menu bar, or an option menu (like a combo box but with
a menu of pull downs).</para>
<para><literal>path</literal> defines the path of the root of the menu.
Basically it is a unique name for the root of the menu, it must be
surrounded by "&lt;&gt;". This is important for the naming of the
accelerators and should be unique. It should be unique both for each
menu and between each program. For example in a program named 'foo', the
main menu should be called "&lt;FooMain&gt;", and a pop-up menu
"&lt;FooImagePopUp&gt;", or similar. What's important is that they're unique.</para>
<para><literal>accel_group</literal> is a pointer to a gtk_accel_group. The
item factory sets up the accelerator table while generating menus. New
accelerator groups are generated by gtk_accel_group_new().</para>
<para>But this is just the first step. To convert the array of GtkItemFactoryEntry
information into widgets the following function is used:</para>
<programlisting role="C">
void gtk_item_factory_create_items( GtkItemFactory *ifactory,
guint n_entries,
GtkItemFactoryEntry *entries,
gpointer callback_data );
</programlisting>
<para><literal>*ifactory</literal> a pointer to the above created item factory.</para>
<para><literal>n_entries</literal> is the number of entries in the
GtkItemFactoryEntry array.</para>
<para><literal>*entries</literal> is a pointer to the GtkItemFactoryEntry array.</para>
<para><literal>callback_data</literal> is what gets passed to all the callback functions
for all the entries with callback_action != 0.</para>
<para>The accelerator group has now been formed, so you'll probably want
to attach it to the window the menu is in:</para>
<programlisting role="C">
void gtk_window_add_accel_group( GtkWindow *window,
GtkAccelGroup *accel_group);
</programlisting>
</sect2>
<!-- ----------------------------------------------------------------- -->
<sect2 id="sec-UsingMenuandItems">
<title>Making use of the menu and its menu items</title>
<para>The last thing to do is make use of the menu. The following function
extracts the relevant widgets from the ItemFactory:</para>
<programlisting role="C">
GtkWidget* gtk_item_factory_get_widget( GtkItemFactory *ifactory,
const gchar *path );
</programlisting>
<para>For instance if an ItemFactory has two entries "/File" and "/File/New",
using a path of "/File" would retrieve a <emphasis>menu</emphasis> widget from the
ItemFactory. Using a path of "/File/New" would retrieve a
<emphasis>menu item</emphasis> widget. This makes it possible to set the initial state
of menu items. For example to set the default radio
item to the one with the path "/Shape/Oval" then the following code would
be used:</para>
<programlisting role="C">
gtk_check_menu_item_set_active(
GTK_CHECK_MENU_ITEM (gtk_item_factory_get_item (item_factory, "/Shape/Oval")),
TRUE);
</programlisting>
<para>Finally to retrieve the root of the menu use gtk_item_factory_get_item()
with a path of "&lt;main&gt;" (or whatever path was used in
gtk_item_factory_new()). In the case of the ItemFactory being created with
type GTK_TYPE_MENU_BAR this returns a menu bar widget. With type GTK_TYPE_MENU
a menu widget is returned. With type GTK_TYPE_OPTION_MENU an option menu
widget is returned.</para>
<para><emphasis>Remember</emphasis> for an entry defined with path "/_File"
the path here is actually "/File".</para>
<para>Now you have a menubar or menu which can be manipulated in the same
way as shown in the
<link linkend="sec-ManualMenuCreation">Manual Menu Creation</link>
section.</para>

Item 1: The menu path. The letter after the underscore indicates an
accelerator key once the menu is open.
Item 2: The accelerator key for the entry
Item 3: The callback function.
Item 4: The callback action. This changes the parameters with
which the function is called. The default is 0.

Here are the possible values:
NULL -> "<Item>"
"" -> "<Item>"
"<Title>" -> create a title item
"<Item>" -> create a simple item
"<CheckItem>" -> create a check item
"<ToggleItem>" -> create a toggle item
"<RadioItem>" -> create a radio item
<path> -> path of a radio item to link against
