Static Public Member Functions
static bool	hasNonDeletableTerminal (const DiagramContent &content)
	DeleteQGraphicsItemCommand::hasNonDeletableTerminal Return true if @content have terminal element which can't be deleted. The reason why a terminal can't be deleted is because they have bridge or belong to a physical terminal with more than one level.

Terminal *	terminalInSamePotential (Terminal *terminal, Conductor *conductor_to_exclude)
	DeleteQGraphicsItemCommand::terminalInSamePotential Return a terminal at the same potential of terminal, by traveling through the conductors connected to terminal only if the owner element of the terminal is not delete by this undo command. Return nullptr if a terminal can't be found.
