A pointer or key event the editor passes on to an operation, having taken what is its own: picks, selecting, dragging handles (see the step editor, crate::step_editor).

Variants

Hover

The pointer moved over the viewport with no button held, shift held or not.

Fields

pointer: Pointer

shift: bool

Leave

The pointer left the viewport.

Click

A primary click that selected nothing: a double one, one while the operation has a tool in hand, one on nothing selectable.

Fields

pointer: Pointer

double: bool

shift: bool

Cancel

What Escape does: end what is in progress — a chain being drawn, the points picked for a tool — and, with nothing in progress, put the tool in hand down. The selection is cleared already.

Confirm

What Enter does: finish what is in progress, a chain being drawn, a constraint to apply; the tool stays in hand.

Delete

What Delete and Backspace do: delete the selection.

Move

The draggable visual key dragged in the plane worked in, from where it was grabbed to where the pointer is now — pointer, with shift held or not. done on release.

Fields

key: String

from: Vector3

to: Vector3

pointer: Pointer

done: bool

shift: bool

Stroke

A drag of the tool in hand, where it strokes (see super::InHand::Strokes): the ray where it went down and the ray where the pointer is now. done on release.

Fields

from: Pointer

to: Pointer

done: bool

shift: bool

Gizmo

A drag of the form’s gizmo (see super::Gizmo): what it did since it started, to apply to the step’s arguments as they were then — which they are again whenever this is sent. done on release. from is the gizmo as the step asked for it when the drag started: where it stood, along what it stands on’s own axes.

Fields

drag: GizmoDrag

from: Gizmo

done: bool

SelectBox

A selection box, with nothing in hand (see StepEditEvent::SelectBox): what it takes of the selectable visuals is the operation’s to decide, from what they stand for, and to select — added to the selection, if add.

Fields

corners: [Pointer; 4]

crossing: bool

add: bool

Key

Any other key, as the browser names it, a letter lowercased: a tool’s shortcut.

Fields

key: String

View

The view settled, up pointing up the screen (see StepEditEvent::View).

Fields

up: Vector3
