Shared Insert Shapes choices and previews
craft_ui::shapes shares the shape/connector menu and original procedural previews contributed in
WordCraft #2142. It provides semantic preset
identities, default ordering, connector/arrow classification, capability filtering and a menu built
on the existing accessible IconButton. This is reusable menu logic as well as painting.
The overlap is concrete: GridCraft's Insert ribbon offers rectangle, rounded rectangle, ellipse, triangle, line, arrow and text box. WordCraft also offers diamond, star, heart and connectors. Each host must filter by what its engine supports; a preview does not imply import/export or rendering support in that app.
let chosen = craft_ui::shapes::menu(ui, 220.0, font, &button_style,
|preset| supported_by_this_app(preset),
|preset| localize(preset.source_label()),
);
if let Some(preset) = chosen {
// Adapt the semantic choice to this app's insertion operation.
}
ShapePreset::key() is a stable choice key, not a universal command payload.
The enum is non-exhaustive: capability adapters should reject unknown future presets by default.
WordCraft maps StraightArrowConnector to kind: "straightConnector", arrow: "end"; GridCraft
must hide it until its own engine supports attachment/routing. An ordinary Arrow remains a
different semantic choice. The library does not silently substitute unsupported objects.
Apps own localization, theme, popup lifetime, current document, insertion coordinates, undo and
selection. Additional actions such as New Drawing Canvas remain app-specific menu entries.
paint_preset is also available for app-owned gallery layouts. The previews use original path
geometry and no external assets. They are UI icons, not editable document geometry or a shape
rendering engine. Star and heart contours honor fill across their full area, including with no
outline; their fixed concave paths use triangle fans around verified interior centers.
Consumer adoption and command adapters are separate work.
