Implementations

impl State

pub fn new() -> State

pub fn query<E>(&mut self, entity: Entity) -> Option<&mut E> where
    E: EventHandler, 

pub fn add_stylesheet(&mut self, path: &str) -> Result<(), Error>

Adds a stylesheet to the application

This function adds the stylesheet path to the application allowing for hot reloading of syles while the application is running.

Examples

state.add_stylesheet("path_to_stylesheet.css");

pub fn add_theme(&mut self, theme: &str)

pub fn add_style_rule(&mut self, style_rule: StyleRule)

Adds a style rule to the application

This function adds a style rule to the application allowing for multiple entites to share the same style properties based on the rule selector.

Examples

Adds a style rule which sets the flex-grow properties of all ‘button’ elements to 1.0:

state.add_style_rule(StyleRule::new(Selector::element("button")).property(Property::FlexGrow(1.0)))

pub fn add_font(&mut self, _name: &str, _path: &str)

pub fn reload_styles(&mut self) -> Result<(), Error>

pub fn insert_event(&mut self, event: Event)

Insert a new event into the application event queue

Inserts a new event into the application event queue that will be processed on the next event loop. If the event unique flag is set to true, only the most recent event of the same type will exist in the queue.

Examples

state.insert_event(Event::new(WindowEvent::WindowClose));

pub fn capture(&mut self, entity: Entity)

pub fn release(&mut self, id: Entity)

pub fn set_focus(&mut self, entity: Entity)

pub fn remove(&mut self, entity: Entity)

pub fn apply_animations(&mut self) -> bool
