Enum MultiSelect 

pub enum MultiSelect {
    Marquee {
        start: Pos2,
        current: Pos2,
        base: Vec<ShapeId>,
    },
    Selected {
        shapes: Vec<ShapeId>,
    },
    Moving {
        shapes: Vec<ShapeId>,
        delta_pos: Vec2,
    },
}

Multi-selection of shapes (blocks and/or ports), entered by drawing a marquee while the Select tool is active. Only two operations are supported on the group: move it rigidly, or delete it (via the Delete button overlay).

Variants

Marquee

Rubber-band in progress; nothing is committed yet. base is the existing selection a shift-marquee extends — empty for a fresh marquee.

Fields

start: Pos2

current: Pos2

base: Vec<ShapeId>

Selected

A committed multi-selection (idle).

Fields

shapes: Vec<ShapeId>

Moving

The whole group is being dragged rigidly.

Fields

shapes: Vec<ShapeId>

delta_pos: Vec2

Implementations

impl MultiSelect

fn render<C: Canvas>( &self, data: &Drawing<'_>, interaction: &Interaction, painter: &mut Style<'_, C>, )

Trait Implementations

impl From<MultiSelect> for Tool

fn from(v: MultiSelect) -> Tool

Converts to this type from the input type.

impl ToolTrait for MultiSelect

fn name(&self) -> ToolName

fn selection(&self) -> Option<Deletable>

The item this tool currently has selected that can be deleted, if any. Used to drive the delete button overlay.

fn preview<C: Canvas>( &mut self, data: &mut Drawing<'_>, interaction: &Interaction, _painter: &mut Style<'_, C>, phase: &PreviewPhase, )

Advance this frame’s drag state and preview the geometry it implies. Runs before Self::widget paints, on every frame of a drag — including one carrying no event at all, which is what a repaint mid-drag looks like.

fn widget<C: Canvas>( &mut self, data: &mut Drawing<'_>, interaction: &Interaction, painter: &mut Style<'_, C>, ) -> Option<Transition>

fn overlay_anchor(&self) -> Option<Pos2>

A world-space point the selection overlay should anchor to, overriding the selection’s bounding box. A route spans a wide bbox but is picked at one spot, so its overlay anchors at the click instead of the whole polyline.

impl TryInto<MultiSelect> for Tool

type Error = &'static str

The type returned in the event of a conversion error.

fn try_into(self) -> Result<MultiSelect, <Self as TryInto<MultiSelect>>::Error>

Performs the conversion.
