ShapeClipboardPayload.h File Reference

ShapeClipboardPayload is the structured representation of a shape-clipboard copy. The editor serializes the selected element subtrees to SVG fragment text and pairs that text with the metadata needed to paste deterministically (document-space bbox at copy time, source element ids, and whether the copy came from a whole-group selection).

Detailed Description

ShapeClipboardPayload is the structured representation of a shape-clipboard copy. The editor serializes the selected element subtrees to SVG fragment text and pairs that text with the metadata needed to paste deterministically (document-space bbox at copy time, source element ids, and whether the copy came from a whole-group selection).

On the system clipboard the payload is stored as plain text, prefixed with a one-line header (# donner-shape-clipboard v1) followed by a small key/value metadata block and the SVG fragment. Generic SVG text without the header is still accepted by parse() as a best-effort import (the metadata fields are left empty), which keeps interoperability with hand-authored fragments.
