Constructor & Destructor Documentation

◆ LinkElementCommand()

LinkElementCommand::LinkElementCommand	(	Element *	element_,
		QUndoCommand *	parent = `nullptr`
	)

LinkElementCommand::LinkElementCommand Constructor.

Parameters

element_	: element where we work the link / unlink
parent	: parent undo

◆ isLinkable()

bool LinkElementCommand::isLinkable	(	Element *	element_a,
		Element *	element_b,
		bool	already_linked = `false`
	)

static

LinkElementCommand::isLinkable.

Parameters

element_a
element_b
already_linked

Returns: true if element_a and element_b can be linked between them. There is few condition to be linked : 1- element_a and element_b must be linkable type. (Ex : A is master and B is slave 'OK', A and B is master 'KO') 2- For element type slave and report (no matter if element is 'A' or 'B'), the element must be free (not connected to an element) 3- we can override the section 2 by set already_linked to true. In this case, if slave or report is already linked to the other element ('A' or 'B') return true, but if linked to another element (not 'A' or 'B') return false
