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().

Implementations

source

impl Menu

source

pub fn new() -> Menu

Creates a new Menu.

The new menu has no items.

Returns

a new Menu

source

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

source

pub fn append_item(&self, item: &MenuItem)

Appends item to the end of self.

See insert_item() for more information.

`item`

a MenuItem to append

source

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

source

pub fn append_submenu(&self, label: Option<&str>, submenu: &impl IsA<MenuModel>)

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

source

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.

source

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

source

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

source

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

source

pub fn insert_submenu(
 &self,
 position: i32,
 label: Option<&str>,
 submenu: &impl IsA<MenuModel>
)

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

source

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

source

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

source

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

source

pub fn prepend_submenu(
 &self,
 label: Option<&str>,
 submenu: &impl IsA<MenuModel>
)

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

source

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

source

pub fn remove_all(&self)

Removes all items in the menu.
