	DACommandsForWorkFlowRemoveLink::DACommandsForWorkFlowRemoveLink
void	redo () override
void	undo () override

详细描述

移除link

构造及析构函数说明

DACommandsForWorkFlowRemoveLink()

DA::DACommandsForWorkFlowRemoveLink::DACommandsForWorkFlowRemoveLink	(	DAAbstractNodeLinkGraphicsItem *	linkitem,
		DANodeGraphicsScene *	sc,
		QUndoCommand *	parent = nullptr
	)

DACommandsForWorkFlowRemoveLink::DACommandsForWorkFlowRemoveLink

此类在

参见

DACommandsForWorkFlowRemoveSelectNodes 中调用

参数

linkitem
sc
parent

针对在命令的构造函数中就直接执行了创建或者删除动作的情况， 创建的命令mNeedDelete初始要为true，否则创建此命令，但没推入stack就会出现内存泄露 反之亦然，删除的命令，needdelete应该为false
