Constructor & Destructor Documentation

MoveDiagramCommand()

MoveDiagramCommand::MoveDiagramCommand	(	ProjectView *	project_view,
		Diagram *	diagram,
		int	new_position,
		QUndoCommand *	parent = nullptr )

MoveDiagramCommand::MoveDiagramCommand.

Parameters

project_view	: project view the diagram's tab belongs to
diagram	: the diagram to move
new_position	: target position (may be out of range, e.g. for a x10/x100 move near either end – ProjectView::setDiagramPosition() clamps it the same way the underlying tab bar always has)
parent
