A
Point
holds the horizontal and vertical coordinates of a two-dimensional point.
The fields in a
Point
are:
| x |
A
double
that represents the horizontal displacement of the point from the origin.
| | y |
A
double
that represents the vertical displacement of the point from the origin.
|
Both numbers often refer to location in the default Yoix coordinate system,
which has its origin at the upper left corner of the screen,
positive x to the right, positive y down, and a resolution of
72 dots per inch.

| Example: |
The program,
import yoix.thread.*;
Frame f;
Point p;
int n;
f.visible = TRUE;
for (n = 0; n < 10; n++) {
p = f.location; // gets current location
p.x += 18; // 0.25 inch right
p.y += 18; // 0.25 inch down
f.location = p; // moves the frame
sleep(1);
}
exit(0);
slowly moves an empty frame down and to the right on your screen,
but only for about 10 seconds.
