Enum CheckMenuKind 

pub enum CheckMenuKind<G> {
    CheckBox(Rc<CheckMenuItem>, G),
    Radio(Rc<CheckMenuItem>, Option<Rc<MenuId>>, G),
    Separate(Rc<CheckMenuItem>),
}

Represents different types of checkable menu items with their associated data

This enum defines three types of checkable menu items:

Variants

CheckBox

• Contains: Rc<CheckMenuItem> and group identifier G
• Purpose: A standard checkbox that can be checked/unchecked independently
• Grouping: Items with the same G value belong to the same logical group

Radio

• Contains: Rc<CheckMenuItem>, optional default MenuId, and group identifier G
• Purpose: A radio button where only one item in the same group can be selected
• Default ID:
  If Some, specifies which menu should be selected when all radios in the group are unchecked.
  If None, no action is taken when all radios are unchecked.
• Grouping: All radio buttons with the same G value form a single selection group

Separate

• Contains: Rc<CheckMenuItem> only
• Purpose: A standalone checkbox with no grouping requirements
• Use case: For independent toggle options that don’t belong to any group

Type Parameters

• G: Group identifier type for organizing related checkable items
  • Used by both CheckBox and Radio variants
  • Must implement Clone (for storing in the manager)
  • Typically use &'static str or enum variants for type safety

Example

use std::rc::Rc;
use tray_controls::CheckMenuKind;
use tray_icon::menu::{CheckMenuItem, MenuId};

// Create a checkbox belonging to "display_group" group
let checkbox = CheckMenuItem::with_id("show_toolbar", "Show Toolbar", true, false, None);
let check_kind = CheckMenuKind::CheckBox(Rc::new(checkbox), "display_group");

// Create a radio button in "theme_group" group with default selection
let radio = CheckMenuItem::with_id("light_theme", "Light Theme", true, true, None);
let radio_kind = CheckMenuKind::Radio(
    Rc::new(radio),
    Some(Rc::new(MenuId::new("light_theme"))),
    "theme_group"
);

// Create a standalone checkbox
let separate = CheckMenuItem::new("Auto-save", true, true, None);
let separate_kind: CheckMenuKind<&str> = CheckMenuKind::Separate(Rc::new(separate));

Variants

CheckBox(Rc<CheckMenuItem>, G)

A standard checkbox with group association

• First parameter: The checkbox menu item
• Second parameter: Group identifier for logical grouping

Radio(Rc<CheckMenuItem>, Option<Rc<MenuId>>, G)

A radio button with optional default selection and group association

• First parameter: The radio button menu item
• Second parameter: Optional default menu ID to select when no radio is checked. If Some, this menu will be selected when all radios in the group are unchecked. If None, no menu will be selected when all radios are unchecked.
• Third parameter: Group identifier for exclusive selection

Separate(Rc<CheckMenuItem>)

A standalone checkbox with no group association

• Parameter: The standalone checkbox menu item
