Routines / Creating and Managing Rectangles

SetRect

To assign coordinates to a rectangle, you can use the SetRect procedure.

PROCEDURE SetRect (VAR r:\xDDRect; left,top,right,bottom:\xDDInteger); 

r

The rectangle to set.

left

The horizontal coordinate of the new upper-left corner of the rectangle.

top

The vertical coordinate of the new upper-left corner of the rectangle.

right

The horizontal coordinate of the new lower-right corner of the rectangle.

bottom

The vertical coordinate of the new lower-right corner of the rectangle.

DESCRIPTION

The SetRect procedure assigns the coordinates you specify in the left, top, right, and bottom parameters to the rectangle that you specify in the r parameter. This procedure is provided to help you shorten your program text. If you want a more readable text, at the expense of source text length, you can instead assign integers (or points) directly into the fields of a Rect record.

Listing 3-4 on page 3-19 illustrates how to use this procedure. The data structure of type Rect is described in the chapter "Basic QuickDraw."
