A
Color
object represents a color by specifying the intensities of the three
primary colors.
The fields in a
Color
are:
| blue |
A
Number
that specifies the intensity of the blue component as a
double
in the range
0.0
to
1.0
or an
int
in the range
0
to
255.
| | green |
A
Number
that specifies the intensity of the green component as a
double
in the range
0.0
to
1.0
or an
int
in the range
0
to
255.
| | red |
A
Number
that specifies the intensity of the red component as a
double
in the range
0.0
to
1.0
or an
int
in the range
0
to
255.
|
An intensity of zero represents no contribution from the component,
while an intensity of
1.0
in the case of a
double
or
255
in the case of an
int
represents the maximum contribution from that component.
Setting all three components to zero represents black,
while setting them all to their maximum value represents white.
The color represents a shade of gray if the three components are
numerically equal and have the same type.

| Example: |
The program,
import yoix.*.*;
int n;
Frame f = {
Array layout = {
new Label {
String tag = "$_name";
String font = "Lucida-bold-14";
Color background = Color.lightGray;
Color foreground = Color.black;
int alignment = CENTER;
}, NORTH,
};
};
f.visible = TRUE;
for (n = 0; n < Color@length; n++) {
f.background = Color[n];
f.components.$_name.text = Color[n]@nameof;
sleep(2);
}
exit(0);
slowly changes the background color assigned to a frame to all the colors
defined in the
yoix.awt.Color
dictionary and shows the name of each selected color in the label that is
positioned at the top of the frame.
