Creates a menu item

Implementations

impl MenuItem

pub fn new(choices: &[&'static str]) -> MenuItem

Initializes a new window, useful for popup menus

pub fn popup(&self, x: i32, y: i32) -> Option<MenuItem>

Creates a popup menu at the specified coordinates and returns its choice

pub fn label(&self) -> Option<String>

Returns the label of the menu item

pub fn set_label(&mut self, txt: &str)

Sets the label of the menu item

pub fn label_type(&self) -> LabelType

Returns the label type of the menu item

pub fn set_label_type(&mut self, typ: LabelType)

Sets the label type of the menu item

pub fn label_color(&self) -> Color

Returns the label color of the menu item

pub fn set_label_color(&mut self, color: Color)

Sets the label color of the menu item

pub fn label_font(&self) -> Font

Returns the label font of the menu item

pub fn set_label_font(&mut self, font: Font)

Sets the label font of the menu item

pub fn label_size(&self) -> i32

Returns the label size of the menu item

pub fn set_label_size(&mut self, sz: i32)

Sets the label size of the menu item

pub fn value(&self) -> bool

Returns the value of the menu item

pub fn set(&mut self)

Sets the menu item

pub fn clear(&mut self)

Clears the menu item

pub fn visible(&self) -> bool

Returns whether the menu item is visible or not

pub fn active(&mut self) -> bool

Returns whether the menu item is active

pub fn activate(&mut self)

Activates the menu item

pub fn deactivate(&mut self)

Deactivates the menu item

pub fn is_submenu(&self) -> bool

Returns whether a menu item is a submenu

pub fn is_checkbox(&self) -> bool

Returns whether a menu item is a checkbox

pub fn is_radio(&self) -> bool

Returns whether a menu item is a radio item

pub fn show(&mut self)

Shows the menu item

pub fn hide(&mut self)

Hides the menu item

pub fn next(&self, idx: i32) -> Option<MenuItem>

Get the next menu item

pub fn children(&self) -> i32

Get children of MenuItem

pub fn at(&self, idx: i32) -> Option<MenuItem>

Get the menu item at idx

pub unsafe fn user_data(&self) -> Option<Box<dyn FnMut()>>

Get the user data

Safety

Can return multiple mutable instances of the user data, which has a different lifetime than the object

pub fn set_callback<F: FnMut(&mut Self) + 'static>(&mut self, cb: F)

Set a callback for the menu item

pub fn emit<T: 'static + Clone + Send + Sync>(
    &mut self,
    sender: Sender<T>,
    msg: T
)

Use a sender to send a message during callback

pub fn was_deleted(&self) -> bool

Check if a menu item was deleted

pub fn draw<M: MenuExt>(
    &self,
    x: i32,
    y: i32,
    w: i32,
    h: i32,
    menu: &M,
    selected: bool
)

Draw a box around the menu item. Requires the call to be made inside a MenuExt-implementing widget’s own draw method

pub fn measure(&self) -> (i32, i32)

Measure the width and height of a menu item

pub unsafe fn set_image<I: ImageExt>(&mut self, image: I)

Set the image of the menu item

Safety

Trying to add a label after adding an image might lead to undefined behavior
