A live preview of one document on one surface. Created by
Draws the current frame into a viewport of width by height.
Pane surfaces only: the content’s intrinsic size for the given
viewport, driving the pane’s scrollbars. Called when the view is
created, the document changes, the viewport resizes, or requestDraw
fires. Omit for fit-to-viewport views; the inspector never measures.
Advances animation state. Return true to keep receiving frames.
The user scrolled the text editor. x/y are scroll percentages and
line is the fractional top visible line. Never fired for scrolls the
host performed on the view’s behalf (scrollEditorTo), so handlers can
follow without echo bookkeeping.
The user scrolled the preview pane (measured views only). x/y are the
new offsets in content coordinates. Never fired for scrolls the host
applied from
Raw wheel/trackpad input over an unmeasured (self-scrolling) preview,
in pixels with positive y scrolling down. Implement to route pane
input into the view’s own scrolling; without it the host falls back
to scrolling the paired text editor.
Pointer input over the preview surface, in the same coordinate space
draw receives. Signatures match the Layout protocol so live artboards
can forward events directly (board:pointerDown(event), …).
Text documents only: the document changed; refresh derived state.
Text documents only: the primary cursor moved. line and column are
zero based code point coordinates.
The surface is closing; release resources.
