Detailed Description

Undoable write of one per-cell parameter across a set of triangles.

Stores the pre-edit value of every touched triangle (NaN for "was unset"). redo() writes the new values, undo() restores the old ones — both through the file-local applyCellParam helper in meshcommands.cpp, so the layer emits attributeChanged and every view refreshes either way. The layer is held as a QPointer: if it is closed, the command becomes inert rather than dangling.

Constructor & Destructor Documentation

◆ MeshSetTriangleAttributeCommand()

MeshSetTriangleAttributeCommand::MeshSetTriangleAttributeCommand	(	SWMM2DMeshLayer *	layer,
		QByteArray	key,
		QVector< int >	triangles,
		QVector< double >	newValues,
		QVector< double >	oldValues,
		const QString &	text,
		MapCanvas *	canvas,
		QUndoCommand *	parent = `nullptr`
	)

Parameters

layer	Mesh layer that owns the triangles.
key	mesh::CellParamSpec key ("mannings", "initDepth", …).
triangles	Triangle indices to write.
newValues	Parallel to `triangles:` the value to write to each.
oldValues	Parallel to `triangles:` the pre-edit value of each (NaN = the attribute was unset).
text	Undo-stack label.
