Struct GizmoGrab 

pub struct GizmoGrab {
    pub view: GizmoView,
    pub part: GizmoPart,
    /* private fields */
}

A drag of a gizmo under way: the gizmo as it was when the part was pressed — what every event of the drag is measured against — the part, how large a reach was there, and how far a turn has gone, to follow it past half a turn.

Fields

view: GizmoView

part: GizmoPart

Implementations

impl GizmoGrab

pub fn new(view: GizmoView, part: GizmoPart, pointer: &Pointer) -> Self

Grabbing part of view with pointer.

pub fn drag( &mut self, from: &Pointer, to: &Pointer, free: bool, ) -> Option<(GizmoDrag, String)>

What the drag from from to to did — snapped unless free — and what to say of it. None where the pointer cannot be followed: looking along an arrow, or along a square’s plane.
