	autoBreakConductors For each terminal of element, check if its dock point lies on an existing conductor. If so, break the conductor and reconnect through the element's terminal. Broken conductors from the same circuit (sharing the same far-end endpoint) are broken together; independent crossing conductors are left untouched.

Function Documentation

autoBreakConductors()

QSet< Terminal * > autoBreakConductors	(	Diagram *	diagram,
		Element *	element,
		QUndoCommand *	parent,
		QList< Conductor * > &	conductors_handled,
		QSet< Terminal * > &	used_terminals )

autoBreakConductors For each terminal of element, check if its dock point lies on an existing conductor. If so, break the conductor and reconnect through the element's terminal. Broken conductors from the same circuit (sharing the same far-end endpoint) are broken together; independent crossing conductors are left untouched.

Parameters

diagram	the diagram containing the conductors
element	the element whose terminals trigger breaks
parent	undo command under which break/reconnect sub-commands are created
conductors_handled	shared list of conductors already claimed by a previous call in the same batch (prevents double-processing when multiple elements are broken in one pass)
used_terminals	shared set of terminals already used as connect_to or other_terminal in the same batch

Returns

set of terminals that were connected to a broken conductor's far-end (useful for preventing duplicate auto-connect)
