Detailed Description

Undoable write of a COMPLETE per-cell infiltration row (method plus every positional parameter plus destination) across a set of triangles — GUI plan §3.5(3), phase GG0c.

MeshSetTriangleAttributeCommand carries one key and parallel double vectors, which is right for a single-column table edit and wrong for "assign this method and its five parameters to 400 selected cells": that has to be one atomic action, and the parameters only mean anything together.

The old state records PROVENANCE, not just values. A cell that was inheriting from its region tag (or the '*' default) must go back to inheriting on undo — restoring a materialised override carrying identical numbers looks correct but silently detaches the cell from its region, so the next region-level edit no longer reaches it. undo() therefore branches on the stored mesh::InfilProvenance: Override restores the old row, Tag / Star / None erase the override through SWMM2DMeshLayer::clearMeshTriangleInfil.

The layer is held as a QPointer: if it is closed, the command becomes inert rather than dangling.

Constructor & Destructor Documentation

◆ MeshSetTriangleInfilCommand()

MeshSetTriangleInfilCommand::MeshSetTriangleInfilCommand	(	SWMM2DMeshLayer *	layer,
		QVector< int >	triangles,
		mesh::InfilRow	newRow,
		QVector< mesh::InfilRow >	oldRows,
		QVector< mesh::InfilProvenance >	oldProv,
		const QString &	text,
		MapCanvas *	canvas,
		QUndoCommand *	parent = `nullptr`
	)

Parameters

layer	Mesh layer that owns the triangles.
triangles	Triangle indices to write.
newRow	The row every triangle in `triangles` receives.
oldRows	Parallel to `triangles:` each cell's pre-edit RESOLVED row.
oldProv	Parallel to `triangles:` where that row came from. Anything but `Override` means the cell was inheriting and undo must erase, not rewrite.
text	Undo-stack label.
