#[repr(transparent)]pub struct Menu { /* private fields */ }
Expand description
Menu
is a simple implementation of MenuModel
.
You populate a Menu
by adding MenuItem
instances to it.
There are some convenience functions 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()
.
Implements
Implementations§
source§impl Menu
impl Menu
sourcepub fn append(&self, label: Option<&str>, detailed_action: Option<&str>)
pub fn append(&self, label: Option<&str>, detailed_action: Option<&str>)
Convenience function for appending a normal menu item to the end of
self
. Combine MenuItem::new()
and insert_item()
for a more
flexible alternative.
label
the section label, or None
detailed_action
the detailed action string, or None
sourcepub fn append_item(&self, item: &MenuItem)
pub fn append_item(&self, item: &MenuItem)
sourcepub fn append_section(&self, label: Option<&str>, section: &impl IsA<MenuModel>)
pub fn append_section(&self, label: Option<&str>, section: &impl IsA<MenuModel>)
Convenience function for appending a section menu item to the end of
self
. Combine MenuItem::new_section()
and insert_item()
for a
more flexible alternative.
label
the section label, or None
section
a MenuModel
with the items of the section
Convenience function for appending a submenu menu item to the end of
self
. Combine MenuItem::new_submenu()
and insert_item()
for a
more flexible alternative.
label
the section label, or None
submenu
a MenuModel
with the items of the submenu
sourcepub fn freeze(&self)
pub fn freeze(&self)
Marks self
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 MenuModelExt::is_mutable()
to begin returning
false
, which has some positive performance implications.
sourcepub fn insert(
&self,
position: i32,
label: Option<&str>,
detailed_action: Option<&str>
)
pub fn insert( &self, position: i32, label: Option<&str>, detailed_action: Option<&str> )
Convenience function for inserting a normal menu item into self
.
Combine MenuItem::new()
and insert_item()
for a more flexible
alternative.
position
the position at which to insert the item
label
the section label, or None
detailed_action
the detailed action string, or None
sourcepub fn insert_item(&self, position: i32, item: &MenuItem)
pub fn insert_item(&self, position: i32, item: &MenuItem)
Inserts item
into self
.
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 self
.
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 insert()
, insert_section()
and
insert_submenu()
as well as “prepend” and “append” variants of
each of these functions.
position
the position at which to insert the item
item
the MenuItem
to insert
sourcepub fn insert_section(
&self,
position: i32,
label: Option<&str>,
section: &impl IsA<MenuModel>
)
pub fn insert_section( &self, position: i32, label: Option<&str>, section: &impl IsA<MenuModel> )
Convenience function for inserting a section menu item into self
.
Combine MenuItem::new_section()
and insert_item()
for a more
flexible alternative.
position
the position at which to insert the item
label
the section label, or None
section
a MenuModel
with the items of the section
Convenience function for inserting a submenu menu item into self
.
Combine MenuItem::new_submenu()
and insert_item()
for a more
flexible alternative.
position
the position at which to insert the item
label
the section label, or None
submenu
a MenuModel
with the items of the submenu
sourcepub fn prepend(&self, label: Option<&str>, detailed_action: Option<&str>)
pub fn prepend(&self, label: Option<&str>, detailed_action: Option<&str>)
Convenience function for prepending a normal menu item to the start
of self
. Combine MenuItem::new()
and insert_item()
for a more
flexible alternative.
label
the section label, or None
detailed_action
the detailed action string, or None
sourcepub fn prepend_item(&self, item: &MenuItem)
pub fn prepend_item(&self, item: &MenuItem)
Prepends item
to the start of self
.
See insert_item()
for more information.
item
a MenuItem
to prepend
sourcepub fn prepend_section(
&self,
label: Option<&str>,
section: &impl IsA<MenuModel>
)
pub fn prepend_section( &self, label: Option<&str>, section: &impl IsA<MenuModel> )
Convenience function for prepending a section menu item to the start
of self
. Combine MenuItem::new_section()
and insert_item()
for
a more flexible alternative.
label
the section label, or None
section
a MenuModel
with the items of the section
Convenience function for prepending a submenu menu item to the start
of self
. Combine MenuItem::new_submenu()
and insert_item()
for
a more flexible alternative.
label
the section label, or None
submenu
a MenuModel
with the items of the submenu
sourcepub fn remove(&self, position: i32)
pub fn remove(&self, position: i32)
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).
position
the position of the item to remove
sourcepub fn remove_all(&self)
pub fn remove_all(&self)
Removes all items in the menu.
