Struct ContextItem 

Source 
pub struct ContextItem<Msg> { /* private fields */ }
Expand description

One row of a menu: an action, a submenu or a gap between groups.

Style keys: context-menu (bg), context-item with hover and disabled, context-item.danger, context-item-shortcut, context-item-chevron, context-item-detail.

Implementations§

Source§

impl<Msg> ContextItem<Msg>

Source

pub fn new(label: impl Into<String>, message: Msg) -> Self

An action labelled label that sends message when chosen.

Source

pub fn submenu( label: impl Into<String>, items: impl IntoIterator<Item = Self>, ) -> Self

A row that opens items beside the menu.

Source

pub fn gap() -> Self

An empty row that separates groups; menus never draw lines.

Source

pub fn icon(self, key: impl Into<String>) -> Self

Icon key drawn before the label.

Source

pub fn shortcut(self, label: impl Into<String>) -> Self

Faint key label kept at the right edge, e.g. "ctrl r". It only describes the key; bind the key itself in the keymap.

Source

pub fn detail(self, text: impl Into<String>) -> Self

A faint note on the right of the row, before the shortcut or the submenu arrow when there is one, e.g. why the entry cannot be used: "bsdtar needed". It is plain text in the quiet tone, drawn on disabled rows too. The menu widens to fit it, and where the menu has no room the note is cut before the label is.

Source

pub fn disabled(self, disabled: bool) -> Self

Greys the row out; it cannot be chosen or highlighted.

Source

pub fn danger(self, danger: bool) -> Self

Draws the row in the danger colour, for destructive actions such as delete.
