void W.draw rectangle(double x 0 , double y 0 , double x 1 , double y 1 ,
color = window :: fgcol)
draws a rectangle with lower left corner (x 0 , y 0 ) and upper
right corner (x 1 , y 1 ).
Precondition: x 0 < x 1 and y 0 < y 1 .

W.draw rectangle(point p, point q, color = window :: fgcol)
draws a rectangle with lower left corner p and upper right
corner q.
Precondition: p < q.
W.draw rectangle(const rectangle& R, color = window :: fgcol)
draws rectangle R.
W.draw box(double x 0 , double y 0 , double x 1 , double y 1 , color c = window :: fgcol)
draws a filled rectangle with lower left corner (x 0 , y 0 ) and
upper right corner (x 1 , y 1 ).
Precondition: x 0 < x 1 and y 0 < y 1 .
W.draw filled rectangle(point p, point q, color = window :: fgcol)
draws a filled rectangle with lower left corner p and upper
right corner q.
Precondition: p < q.
W.draw filled rectangle(const rectangle& R, color = window :: fgcol)
draws rectangle R.
W.draw box(point p, point q, color c = window :: fgcol)
same as draw filled rectangle(p, q, c).
W.draw box(const rectangle& R, color c = window :: fgcol)
same as draw filled rectangle(p, q, c).
W.draw roundrect(double x 0 , double y 0 , double x 1 , double y 1 , double rndness,
color col = window :: fgcol)
draws a rectangle (x 0 , y 0 , x 1 , y 1 ) with round corners. The
rndness argument must be real number in the intervall
[0, 1] and defines the “roundness” of the rectangle.
W.draw roundrect(point p, point q, double rndness, color col = window :: fgcol)
draws a round rectangle with lower left corner p, upper
right corner q, and roundness rndness.
W.draw roundbox(double x 0 , double y 0 , double x 1 , double y 1 , double rndness,
color col = window :: fgcol)
draws a filled rectangle (x 0 , y 0 , x 1 , y 1 ) with round corners.
The rndness argument must be real number in the intervall
[0, 1] and defined the “roundness” of the rectangle.
