Class PreviewOverlayPainter

Everything drawn over the rendered frame in response to the mouse: hover and selection chrome, the transform/rotate handles, the live gesture readout, and the cursor the pointer shows over each of them.

Syntax

public sealed class PreviewOverlayPainter

Remarks

The drawing side of direct manipulation, where PreviewGestureCoordinator is the input side. It reads that coordinator rather than tracking selection or hover itself — a second copy of either would only ever be right until the two disagreed — and hands the actual painting to the stateless PreviewOverlayGui.

Constructors

PreviewOverlayPainter(Func<PreviewSceneRenderer>, PreviewGestureCoordinator)

Creates a painter.

Declaration

public PreviewOverlayPainter(Func<PreviewSceneRenderer> renderer, PreviewGestureCoordinator coordinator)

Parameters

Type	Name	Description
Func<PreviewSceneRenderer>	renderer	The preview's current scene renderer, re-read on every call.
PreviewGestureCoordinator	coordinator	The coordinator whose selection, hover and gesture state this draws.

Methods

Draw(Rect)

Draws hover and selection chrome for the current frame, clipped to it so nothing leaks past the scrollview when the preview is zoomed and panned.

Declaration

public void Draw(Rect frame)

Parameters

Type	Name	Description
Rect	frame	The rectangle the preview is drawn into, in screen pixels.

Remarks

UnityEditor.Handles calls only work inside an IMGUI window wrapped in Handles.BeginGUI/ EndGUI, and everything inside GUI.BeginClip draws in coordinates relative to the clip's origin — so every quad is translated by -frame.position before it reaches PreviewOverlayGui, which otherwise knows nothing about frames or clipping.
