* DrawView.h
* Created by Ken Anderson, Ken Fromm
*
* The purpose of the application is to show different methods for drawing paths and
* the times obtained for each method. Lines are used in the construction of the paths
* but curves and arcs could be used as well.
*
* This file contains the class definition for DrawView, a subclass of View.
* Instance Variable:
* Each index for the arrays below corresponds to one line.
* X[ ], Y[ ] - Initial points, used with moveto. Selected randomly.
* X1[ ], Y1[ ] - End points, used with lineto. Selected randomly.
* C[ ], W[ ] - Line color and line width. Chosen specifically/selected randomly.
* LineColor, LineWidth - The current line color and line width as passed in by
* the sliders.
*
* TotalLines - the number of lines that have been made for a draw operation.
* PSTrace - Boolean value indicating whether to trace the PostScript.
* Random - Boolean value indicating whether to select the line color and line
* width at random or to use the current values of the slider controls.
*
* matrixDisplayTimes - id to identify to display the display time fields.
* enableSliderColor, enableSliderWidth - id's of sliders.
