Member Function Documentation

get_name()

Glib::ustring Gio::MenuLinkIter::get_name

(

)

const

Gets the name of the link at the current iterator position.

The iterator is not advanced.

Since glibmm 2.32

Returns

The type of the link.

get_next()

bool Gio::MenuLinkIter::get_next	(	Glib::ustring &	out_link,
		Glib::RefPtr< MenuModel > &	value )

This function combines g_menu_link_iter_next() with g_menu_link_iter_get_name() and g_menu_link_iter_get_value().

First the iterator is advanced to the next (possibly first) link. If that fails, then false is returned and there are no other effects.

If successful, out_link and value are set to the name and MenuModel of the link that has just been advanced to. At this point, g_menu_link_iter_get_name() and g_menu_link_iter_get_value() will return the same values again.

The value returned in out_link remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using Glib::object_unref() when it is no longer in use.

Since glibmm 2.32

Parameters

out_link	The name of the link.
value	The linked MenuModel.

Returns

true on success, or false if there is no additional link.

get_type()

GType Gio::MenuLinkIter::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

get_value() [1/2]

Glib::RefPtr< MenuModel > Gio::MenuLinkIter::get_value

(

)

Gets the linked MenuModel at the current iterator position.

The iterator is not advanced.

Since glibmm 2.32

Returns

The MenuModel that is linked to.

get_value() [2/2]

Glib::RefPtr< const MenuModel > Gio::MenuLinkIter::get_value

(

)

const

Gets the linked MenuModel at the current iterator position.

The iterator is not advanced.

Since glibmm 2.32

Returns

The MenuModel that is linked to.

gobj() [1/2]

GMenuLinkIter * Gio::MenuLinkIter::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GMenuLinkIter * Gio::MenuLinkIter::gobj ( ) const

inline

Provides access to the underlying C GObject.

gobj_copy()

GMenuLinkIter * Gio::MenuLinkIter::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

next()

bool Gio::MenuLinkIter::next

(

)

Attempts to advance the iterator to the next (possibly first) link.

true is returned on success, or false if there are no more links.

You must call this function when you first acquire the iterator to advance it to the first link (and determine if the first link exists at all).

Since glibmm 2.32

Returns

true on success, or false when there are no more links.

operator=()

MenuLinkIter & Gio::MenuLinkIter::operator= ( MenuLinkIter && src )

wrap()

Glib::RefPtr< Gio::MenuLinkIter > wrap ( GMenuLinkIter * object, bool take_copy = false )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
