Module pick_wire 

Picking parts of a window drawn by another process: what the desktop asks the app that draws a window while a person points at what is wrong (crate::floating_surface::FloatingSurfaceHostMessage::Pick), and what the app answers from its own retained tree with answer (crate::floating_surface::FloatingSurfaceClientMessage::PickAnswered).

Everything is in the window’s logical coordinates, rectangles as [x0, y0, x1, y1]. The desktop names the app by the launcher’s id, never by anything in an answer.

Structs

CapturedPart

A picked part’s texts, read again from the tree.

CapturedText

One text under a picked part.

PartToCapture

One picked part, by the path and bounds an earlier answer gave.

PickedPart

A part a person can pick.

RecentAction

Something the person last did through a control of the app: names only, never arguments.

Enums

PickAnswer

A window’s answer to a PickQuery.

PickQuery

What the desktop asks a window while a person picks.

Constants

MAX_CAPTURES

Most parts one capture is asked for.

MAX_PARTS

Most parts one answer names: the chain under a point is never this deep in a person’s interface, and a dragged rectangle asks for fewer.

MAX_RECENT

Most recent actions a capture carries.

Functions

answer

Answer query from the tree under root.

rect_array

rect as the wire carries it.

rect_of

A rectangle from the wire: finite, with an area.
