pub fn new<S>(text: S, enabled: bool) -> Submenu
where S: AsRef<str>,

Create a new submenu.

text could optionally contain an & before a character to assign this character as the mnemonic for this submenu. To display a & without assigning a mnemenonic, use &&.

Source

pub fn with_id<I, S>(id: I, text: S, enabled: bool) -> Submenu
where I: Into<MenuId>, S: AsRef<str>,

Create a new submenu with the specified id.

text could optionally contain an & before a character to assign this character as the mnemonic for this submenu. To display a & without assigning a mnemenonic, use &&.

Source

pub fn with_items<S>( text: S, enabled: bool, items: &[&dyn IsMenuItem], ) -> Result<Submenu, Error>
where S: AsRef<str>,

Creates a new submenu with given items. It calls Submenu::new and Submenu::append_items internally.

Source

pub fn with_id_and_items<I, S>( id: I, text: S, enabled: bool, items: &[&dyn IsMenuItem], ) -> Result<Submenu, Error>
where I: Into<MenuId>, S: AsRef<str>,

Creates a new submenu with the specified id and given items. It calls Submenu::new and Submenu::append_items internally.

Source

pub fn id(&self) -> &MenuId

Returns a unique identifier associated with this submenu.

Source

pub fn append(&self, item: &dyn IsMenuItem) -> Result<(), Error>

Add a menu item to the end of this menu.

Source

pub fn append_items(&self, items: &[&dyn IsMenuItem]) -> Result<(), Error>

Add menu items to the end of this submenu. It calls Submenu::append in a loop.

pub fn prepend(&self, item: &dyn IsMenuItem) -> Result<(), Error>

Add a menu item to the beginning of this submenu.

Source

pub fn prepend_items(&self, items: &[&dyn IsMenuItem]) -> Result<(), Error>

Add menu items to the beginning of this submenu. It calls Menu::prepend on the first element and passes the rest to Menu::insert_items with position of 1.

Source

pub fn insert( &self, item: &dyn IsMenuItem, position: usize, ) -> Result<(), Error>

Source

pub fn insert_items( &self, items: &[&dyn IsMenuItem], position: usize, ) -> Result<(), Error>

Insert menu items at the specified postion in the submenu.
