Undoable commands. More...

Classes
class	AddLayerCmd
	Command for adding layers. More...
class	AddShapeCmd
	Command for adding shapes. The command needs to manage shapes' lifecycle, but doesn't need to manage layers' lifecycle. More...
class	BaseCmd
	A class template for undoable commands, along with undo() / redo() implementation. More...
class	JoinedCmd
	A group of commands that can be considered as a single step in undo/redo. More...
class	RemoveLayerCmd
	Command for removing layers. More...
class	RemoveShapeCmd
	Command for removing shapes. The command needs to manage shapes' lifecycle, but doesn't need to manage layers' lifecycle. More...
class	SelectCmd
	Command for selection changes in document. More...
class	SetCmd
	Command for changing objects' property, and the property can be "passed by value". More...
class	SetRefCmd
	Command for changing objects' property, and the property is usually "passed by reference". More...
