Implementations

impl HandRadial

pub fn item<C: FnMut() + 'static>( name: impl AsRef<str>, image: Option<Material>, callback: C, action: HandMenuAction, ) -> Self

Creates a new HandRadial item.

• name - Display name of the item.
• image - Image to display on the item.
• callback - The callback that should be performed when this menu item is selected.
• action - Describes the menu related behavior of this menu item, should it close the menu? Open another layer? Check/Uncheck this item? Go back to the previous menu?

pub fn layer( name: impl AsRef<str>, image: Option<Material>, start_angle: Option<f32>, items: Vec<HandRadial>, ) -> Self

Creates a new HandRadial layer.

• name - Name of the layer, this is used for layer traversal, so make sure you get the spelling right! Perhaps use const strings for these.
• image - Image to display in the center of the radial menu.
• start_angle - An angle offset for the layer, if you want a specific orientation for the menu’s contents. Note this may not behave as expected if you’re setting this manually and using the backAngle as well.
• items - A list of menu items to display in this menu layer.

pub fn items_count(&self) -> usize

Returns the number of items in this layer. 0 if this is an item.

pub fn items(&self) -> &Vec<Rc<HandRadial>>

Returns the items in this layer. Empty if this is an item.

pub fn is_back_action(&self) -> bool

Returns true if this is an item and it is a back action.

pub fn is_checked_action(&self) -> Option<u8>

Returns the group number if this is an item and it is a checked action.

pub fn is_unchecked_action(&self) -> Option<u8>

Returns the group number if this is an item and it is an unchecked action.

pub fn get_start_angle(&self) -> f32

Returns the start angle of the layer. 0.0 if this is an item.

pub fn get_back_angle(&self) -> f32

Returns the back angle of the layer. 0.0 if this is an item.

pub fn get_name(&self) -> &str

Returns the name of the item or layer.
