Detailed Description
A simple implementation of MenuModel .
You populate a Menu by adding MenuItem instances to it.
There are some convenience methods to allow you to directly add items (avoiding MenuItem ) for the common cases. To add a regular item, use insert() . To add a section, use insert_section() . To add a submenu, use insert_submenu() .

Member Function Documentation
void Gio::Menu::append | ( | const Glib::ustring & | label , |
const Glib::ustring & | detailed_action | ||
) |
Convenience function for appending a normal menu item to the end of menu .
Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.detailed_action The detailed action string, or nullptr
.
void Gio::Menu::append | ( | const Glib::ustring & | label | ) |
A append() convenience overload.
void Gio::Menu::append_item | ( | const Glib::RefPtr < MenuItem >& | item | ) |
Appends item to the end of menu .
See g_menu_insert_item() for more information.
- Parameters
-
item A MenuItem to append.
void Gio::Menu::append_section | ( | const Glib::ustring & | label , |
const Glib::RefPtr < MenuModel >& | section | ||
) |
Convenience function for appending a section menu item to the end of menu .
Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.section A MenuModel with the items of the section.
void Gio::Menu::append_section | ( | const Glib::RefPtr < MenuModel >& | section | ) |
A append_section() convenience overload.
void Gio::Menu::append_submenu | ( | const Glib::ustring & | label , |
const Glib::RefPtr < MenuModel >& | submenu | ||
) |
Convenience function for appending a submenu menu item to the end of menu .
Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.submenu A MenuModel with the items of the submenu.
|
static |
void Gio::Menu::freeze | ( | ) |
Marks menu as frozen.
After the menu is frozen, it is an error to attempt to make any changes to it. In effect this means that the Menu API must no longer be used.
This function causes g_menu_model_is_mutable() to begin returning
false
, which has some positive performance implications.
|
static |
Get the GType for this class, for use with the underlying GObject type system.
|
inline |
Provides access to the underlying C GObject.
|
inline |
Provides access to the underlying C GObject.
GMenu* Gio::Menu::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
void Gio::Menu::insert | ( | int | position , |
const Glib::ustring & | label , | ||
const Glib::ustring & | detailed_action | ||
) |
Convenience function for inserting a normal menu item into menu .
Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
position The position at which to insert the item. label The section label, or nullptr
.detailed_action The detailed action string, or nullptr
.
void Gio::Menu::insert | ( | int | position , |
const Glib::ustring & | label | ||
) |
A insert() convenience overload.
void Gio::Menu::insert_item | ( | int | position , |
const Glib::RefPtr < MenuItem >& | item | ||
) |
Inserts item into menu .
The "insertion" is actually done by copying all of the attribute and link values of item and using them to form a new item within menu . As such, item itself is not really inserted, but rather, a menu item that is exactly the same as the one presently described by item .
This means that item is essentially useless after the insertion occurs. Any changes you make to it are ignored unless it is inserted again (at which point its updated values will be copied).
You should probably just free item once you're done.
There are many convenience functions to take care of common cases. See g_menu_insert(), g_menu_insert_section() and g_menu_insert_submenu() as well as "prepend" and "append" variants of each of these functions.
- Parameters
-
position The position at which to insert the item. item The MenuItem to insert.
void Gio::Menu::insert_section | ( | int | position , |
const Glib::ustring & | label , | ||
const Glib::RefPtr < MenuModel >& | section | ||
) |
Convenience function for inserting a section menu item into menu .
Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
position The position at which to insert the item. label The section label, or nullptr
.section A MenuModel with the items of the section.
void Gio::Menu::insert_section | ( | int | position , |
const Glib::RefPtr < MenuModel >& | section | ||
) |
A insert_section() convenience overload.
void Gio::Menu::insert_submenu | ( | int | position , |
const Glib::ustring & | label , | ||
const Glib::RefPtr < MenuModel >& | submenu | ||
) |
Convenience function for inserting a submenu menu item into menu .
Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
position The position at which to insert the item. label The section label, or nullptr
.submenu A MenuModel with the items of the submenu.
void Gio::Menu::prepend | ( | const Glib::ustring & | label , |
const Glib::ustring & | detailed_action | ||
) |
Convenience function for prepending a normal menu item to the start of menu .
Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.detailed_action The detailed action string, or nullptr
.
void Gio::Menu::prepend | ( | const Glib::ustring & | label | ) |
A prepend() convenience overload.
void Gio::Menu::prepend_item | ( | const Glib::RefPtr < MenuItem >& | item | ) |
Prepends item to the start of menu .
See g_menu_insert_item() for more information.
- Parameters
-
item A MenuItem to prepend.
void Gio::Menu::prepend_section | ( | const Glib::ustring & | label , |
const Glib::RefPtr < MenuModel >& | section | ||
) |
Convenience function for prepending a section menu item to the start of menu .
Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.section A MenuModel with the items of the section.
void Gio::Menu::prepend_section | ( | const Glib::RefPtr < MenuModel >& | section | ) |
A prepend_section() convenience overload.
void Gio::Menu::prepend_submenu | ( | const Glib::ustring & | label , |
const Glib::RefPtr < MenuModel >& | submenu | ||
) |
Convenience function for prepending a submenu menu item to the start of menu .
Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.
- Parameters
-
label The section label, or nullptr
.submenu A MenuModel with the items of the submenu.
void Gio::Menu::remove | ( | int | position | ) |
Removes an item from the menu.
position gives the index of the item to remove.
It is an error if position is not in range the range from 0 to one less than the number of items in the menu.
It is not possible to remove items by identity since items are added to the menu simply by copying their links and attributes (ie: identity of the item itself is not preserved).
- Parameters
-
position The position of the item to remove.
void Gio::Menu::remove_all | ( | ) |
Removes all items in the menu.
