Expand description

BaseShape is what every shape can answer without knowing the document: where it sits, what its labels are, where its pins hang, and how it paints. Writes are not here — they are commits, emitted by crate::edit against the document the gesture read.

Required Methods§

Source

fn gui_rect(&self) -> Rect

Provided Methods§

Source

fn pin_drop_candidate( &self, pin_id: PinId, side: PinSide, raw_offset_px: f32, ) -> Option<u32>

The slot a dragged pin would snap to (its grid offset), or None if no free slot is available. Read-only: the drop’s own write is crate::edit::geometry::move_pin, and both resolve the same slot so the preview lands where the commit will.

Source

fn pin_text_rect<R: Renderer>( &self, id: PinId, painter: &Style<'_, R>, ) -> Option<Rect>

Source

fn pin_type_rect<R: Renderer>( &self, id: PinId, painter: &Style<'_, R>, ) -> Option<Rect>

Bounding box of a pin’s type label (the smaller second line below the name), for hit-testing a double-click on the type. None for shapes without such a pin.

Source

fn tag_text_rect_for<R: Renderer>( &self, id: PinId, text: &str, painter: &Style<'_, R>, ) -> Option<Rect>

Bounding box of a pin’s tag label (drawn above the stub line), sized for an explicit text. None if the shape has no such pin. Callers pass the “+tag” placeholder for an empty tag so the prompt stays a hit/edit target.
