Detailed Description

This class represents the action of merging 2 to n cells into a single one.

Constructor & Destructor Documentation

MergeCellsCommand()

MergeCellsCommand::MergeCellsCommand	(	const TitleBlockTemplateCellsSet &	merged_cells,
		TitleBlockTemplate *	tbtemplate = nullptr,
		QUndoCommand *	parent = nullptr
	)

Parameters

merged_cells	Cells to be merged together into a single one.
tbtemplate	Modified title block template.
parent	Parent QUndoCommand.
