Create a new score element from a Score

pub fn width(&self) -> f32

Trait Implementations

impl Element for ScoreElement

fn limits(&self, _ctx: &BasicContext<'_>) -> ViewLimits

Returns the size limits of this element.

fn draw(&self, _ctx: &Context<'_>)

Draws this element.

fn as_any(&self) -> &dyn Any

Returns this element as Any for downcasting.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns this element as mutable Any for downcasting.

fn stretch(&self) -> ViewStretch

Returns the stretch factor of this element.

fn span(&self) -> u32

Returns the span (for grid layouts).

fn hit_test( &self, ctx: &Context<'_>, p: Point, leaf: bool, control: bool, ) -> Option<&(dyn Element + 'static)>

Performs hit testing to find the element at the given point.

fn contains(&self, ctx: &Context<'_>, p: Point) -> bool

Returns true if the element contains the given point (within current bounds).

fn draw_overlay(&self, _ctx: &Context<'_>)

Draws transient overlay content (e.g. an expanded dropdown/popup) that must appear above every sibling, regardless of tree order. Containers call this in a second pass after all children have drawn their normal content, so overlays are never occluded by later siblings. Wrapper elements should forward this to their subject; the default is a no-op.

fn layout(&mut self, ctx: &Context<'_>)

Performs layout calculations.

fn refresh(&self, ctx: &Context<'_>, outward: i32)

Refreshes the element, triggering a redraw.

fn wants_control(&self) -> bool

Returns true if this element wants to receive control events.

fn click(&mut self, ctx: &Context<'_>, btn: MouseButton) -> bool

Handles mouse click events.

fn handle_click(&self, _ctx: &Context<'_>, _btn: MouseButton) -> bool

Handles mouse click events (immutable version for use with Arc).

fn drag(&mut self, ctx: &Context<'_>, btn: MouseButton)

Handles mouse drag events.

fn handle_drag(&self, _ctx: &Context<'_>, _btn: MouseButton)

Handles mouse drag events (immutable version for use with Arc).

fn key(&mut self, ctx: &Context<'_>, k: KeyInfo) -> bool

Handles keyboard events.

fn handle_key(&self, _ctx: &Context<'_>, _k: KeyInfo) -> bool

Handles keyboard events (immutable version for use with Arc).

fn text(&mut self, ctx: &Context<'_>, info: TextInfo) -> bool

Handles text input events.

fn handle_text(&self, _ctx: &Context<'_>, _info: TextInfo) -> bool

Handles text input events (immutable version for use with Arc).

fn cursor( &mut self, ctx: &Context<'_>, p: Point, status: CursorTracking, ) -> bool

Handles cursor (mouse move) events.

fn scroll(&mut self, ctx: &Context<'_>, dir: Point, p: Point) -> bool

Handles scroll events.

fn handle_scroll(&self, _ctx: &Context<'_>, _dir: Point, _p: Point) -> bool

Handles scroll events (immutable version for use with Arc).

fn enable(&mut self, state: bool)

Enables or disables the element.

fn is_enabled(&self) -> bool

Returns true if the element is enabled.

fn wants_focus(&self) -> bool

Returns true if this element wants to receive focus.

fn begin_focus(&mut self, req: FocusRequest)

Called when the element begins receiving focus.

fn end_focus(&mut self) -> bool

Called when the element loses focus.

fn focus(&self) -> Option<&(dyn Element + 'static)>

Returns the currently focused child element, if any.

fn focus_mut(&mut self) -> Option<&mut (dyn Element + 'static)>

Returns a mutable reference to the currently focused child element, if any.

fn clear_focus(&self)

Clears focus from this element and all children (immutable version). This is used when clicking elsewhere to unfocus text inputs, etc.

fn track_drop( &mut self, ctx: &Context<'_>, info: &DropInfo, status: CursorTracking, )

Handles drag tracking events.

fn drop(&mut self, ctx: &Context<'_>, info: &DropInfo) -> bool

Handles drop events.

fn class_name(&self) -> &'static str

Returns the class name of this element (for debugging).
