Struct Menubar

pub struct Menubar {
    pub autohide: bool,
    /* private fields */
}

Shows a single-line list of items, with pop-up menus when one is selected.

The Cursive root already includes a menubar that you just need to configure.

Fields

autohide: bool

TODO: move this out of this view.

Implementations

impl Menubar

pub fn new() -> Menubar

Creates a new, empty menubar.

pub fn receive_events(&self) -> bool

True if we should be receiving events.

pub fn has_submenu(&self) -> bool

True if some submenus are visible.

pub fn visible(&self) -> bool

Returns true if we should be drawn.

pub fn insert(&mut self, i: usize, item: Item) -> &mut Menubar

Adds a new item to the menubar.

pub fn item(&mut self, item: Item) -> &mut Menubar

Adds a new item to the menubar.

pub fn add_subtree<S>(&mut self, title: S, menu: Tree) -> &mut Menubar

where S: Into<SpannedString<Style>>,

Adds a new item to the menubar.

The item will use the given title, and on selection, will open a popup-menu with the given menu tree.

pub fn add_delimiter(&mut self) -> &mut Menubar

Adds a delimiter to the menubar.

pub fn add_leaf<S, F>(&mut self, title: S, cb: F) -> &mut Menubar

where S: Into<SpannedString<Style>>, F: 'static + Fn(&mut Cursive) + Send + Sync,

Adds a leaf node to the menubar.

pub fn insert_subtree<S>( &mut self, i: usize, title: S, menu: Tree, ) -> &mut Menubar

where S: Into<SpannedString<Style>>,

Insert a new item at the given position.

pub fn insert_delimiter(&mut self, i: usize) -> &mut Menubar

Inserts a new delimiter at the given position.

It will show up as |.

pub fn insert_leaf<S, F>(&mut self, i: usize, title: S, cb: F) -> &mut Menubar

where S: Into<SpannedString<Style>>, F: 'static + Fn(&mut Cursive) + Send + Sync,

Inserts a new leaf node at the given position.

It will be directly actionable.

pub fn clear(&mut self)

Removes all menu items from this menubar.

pub fn len(&self) -> usize

Returns the number of items in this menubar.

pub fn is_empty(&self) -> bool

Returns true if this menubar is empty.

pub fn get_subtree(&mut self, i: usize) -> Option<&mut Tree>

Returns the item at the given position.

Returns None if i > self.len()

pub fn find_subtree(&mut self, label: &str) -> Option<&mut Tree>

Looks for an item with the given label.

pub fn find_position(&mut self, label: &str) -> Option<usize>

Returns the position of the item with the given label.

Returns None if no such label was found.

pub fn remove(&mut self, i: usize)

Remove the item at the given position.

Trait Implementations

impl Default for Menubar

fn default() -> Menubar

Returns the “default value” for a type.

impl View for Menubar

fn draw(&self, printer: &Printer<'_, '_>)

Draws the view with the given printer (includes bounds) and focus.

fn on_event(&mut self, event: Event) -> EventResult

Called when an event is received (key press, mouse event, …).

fn take_focus(&mut self, _: Direction) -> Result<EventResult, CannotFocus>

Attempt to give this view the focus.

fn required_size(&mut self, _: XY<usize>) -> XY<usize>

Returns the minimum size the view requires with the given restrictions.

fn important_area(&self, size: XY<usize>) -> Rect

What part of the view is important and should be visible?

fn layout(&mut self, _: XY<usize>)

Called once the size for this view has been decided.

fn needs_relayout(&self) -> bool

Should return true if the view content changed since the last call to layout().

fn call_on_any( &mut self, _: &Selector<'_>, _: &mut dyn FnMut(&mut (dyn View + 'static)), )

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, _: &Selector<'_>) -> Result<EventResult, ViewNotFound>

Moves the focus to the view identified by the given selector.

fn type_name(&self) -> &'static str

Returns the type of this view.
