Module selection_bounds 

World-space bounding boxes for the current selection. Shared by the selection frames (drawn on the canvas) and the selection overlay (placed in screen space), so both agree on what region a selection occupies.

Functions

pins_bounds 🔒

The union of the drawn extent (stub + name/type/tag labels) of each pin. Needs the painter to measure label text.

route_bounds 🔒

The bounding box of a route’s polyline, expanded slightly so an axis-aligned route (zero-width or zero-height bbox) still yields a usable region.

selection_world_bounds

The world-space bounding box of whatever sel covers, or None if it can’t be resolved. Used to place the selection overlay relative to the selection.

shapes_bounds 🔒

The union of the given shapes’ gui_rects, or None if none resolve.
