NAME
ColorData, GSData, MobilityData, MoveData, VoidData - Data subclasses for storing common undo information SYNOPSIS
#include <Unidraw/Commands/datas.h> DESCRIPTION
The Unidraw library predefines several Data subclasses for storing common undo information: ColorData stores two PSColors (usually repre- senting foreground and background colors), while GSData stores a complete set of graphics state in a FullGraphic object. MobilityData stores the mobility and graphics state information needed to undo a change in mobility. MoveData stores a horizontal and vertical distance. VoidData stores a void pointer as a useful alternative to deriving trivially from Data just to store one word of information. COLORDATA PUBLIC OPERATIONS
ColorData(PSColor*, PSColor*) Create a ColorData instance, supplying the PSColor objects it stores. GSDATA PUBLIC OPERATIONS
GSData(Graphic*) Create a GSData instance, supplying the Graphic object from which to copy a complete set of graphics state. The GSData constructor copies this information into its _gs member, from whence it can be retrieved later. MOBILITYDATA PUBLIC OPERATIONS
MobilityData(Mobility, Graphic*) Create a MobilityData instance, supplying the mobility and a Graphic object from which to copy a complete set of graphics state. The MobilityData constructor copies the graphic into its _gs member, from whence it can be retrieved later. MOVEDATA PUBLIC OPERATIONS
MoveData(float, float) Create a MoveData instance, supplying two floating point numbers that normally represent horizontal and vertical movement. VOIDDATA PUBLIC OPERATIONS
VoidData(void*) Create a VoidData instance, supplying a pointer to an object of unknown type. SEE ALSO
