Member Function Documentation

◆ get_name()

Glib::ustring Gio::MenuAttributeIter::get_name ( ) const

Gets the name of the attribute at the current iterator position, as a string.

The iterator is not advanced.

Since glibmm 2.32:

Returns: The name of the attribute.

◆ get_next()

bool Gio::MenuAttributeIter::get_next	(	Glib::ustring &	out_name,
		Glib::VariantBase &	value
	)

This function combines g_menu_attribute_iter_next() with g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value().

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

If successful, name and value are set to the name and value of the attribute that has just been advanced to. At this point, g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value() will return the same values again.

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

Since glibmm 2.32:

Parameters

out_name	The type of the attribute.
value	The attribute value.

Returns: true on success, or false if there is no additional attribute.

◆ get_type()

static GType Gio::MenuAttributeIter::get_type ( )

static

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

◆ get_value()

Glib::VariantBase Gio::MenuAttributeIter::get_value ( ) const

Gets the value of the attribute at the current iterator position.

The iterator is not advanced.

Since glibmm 2.32:

Returns: The value of the current attribute.

◆ gobj() [1/2]

GMenuAttributeIter * Gio::MenuAttributeIter::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GMenuAttributeIter * Gio::MenuAttributeIter::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GMenuAttributeIter * Gio::MenuAttributeIter::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::MenuAttributeIter::next ( )

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

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

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

Since glibmm 2.32:

Returns: true on success, or false when there are no more attributes.
