Implementations

impl ElementContext

pub fn hot_active(&self, id: impl Into<ElementId>) -> HotActive

pub fn btn_hot_active(&mut self, id: impl Into<ElementId>) -> (HotActive, bool)

pub fn is_hovered(&self, id: impl Into<ElementId>) -> bool

pub fn any_element_with_id_hovered(&self) -> bool

useful for overlay ui in games, to not check for camera click raycasts into the scene ] if some part of the ui is hovered in front of it

pub fn get_computed_bounds( &self, id: impl Into<ElementId>, ) -> Option<ComputedBounds>

pub fn new() -> Self

pub fn set_input(&mut self, input: &Input)

pub fn set_input_scaled_to_fixed_height( &mut self, input: &Input, screen_size: PhysicalSize<u32>, fixed_height: f32, )

Use this, if we layout the UI always at a fixed height, but scale it up by some factor in the shader to match the actual screen resolution

input is taken at screen resolution. screen_size is the actual screen resolution. fixed_height is the height of our ui layout. (width is calculated to be proportional to the screen_size, both scaled up to screen_size in rendering later).

pub fn set_cursor_delta(&mut self, cursor_delta: Vec2)

pub fn set_mouse_buttons(&mut self, mouse_buttons: MouseButtonState)

pub fn set_cursor_pos(&mut self, cursor_pos: Vec2)

pub fn set_hot_active(&mut self, id: ElementId, state: HotActive)
