(String str [, double alpha]) |
typedict.Graphics |
| |
Draws the characters in
str
on
drawable
starting at the current point, which is adjusted as the characters in
str
are printed.
Character outlines come from
font
and are painted using
foreground
and the optional
alpha
argument, which should be a number between
0.0
and
1.0,
as the alpha value.
Omitting
alpha
or supplying a value of
1.0
are equivalent.
show
aborts with a
nocurrentpoint
error if
path
is empty.
show
may or may not process the characters in
str
individually (the details are font and implementation dependent),
but it will always be the simplest and fastest way to paint
str
on
drawable.
The first character in
str
is placed at the current point, which is adjusted horizontally by the
width of that character before the second character is printed.
The process stops after the last character in
str
is printed.

| Example: |
The program,
import yoix.*.*;
JFrame f = {
Graphics graphics = {
String font = "Lucida-bold-24";
Color foreground = Color.red;
};
paint(Rectangle r) {
String text = "hello, world";
graphics { // "named block"
gsave();
rectclip(r);
translate(drawable.size.width/2, drawable.size.height/2);
rotate(-30);
moveto(-stringwidth(text)/2, 0);
show(text);
grestore();
}
}
};
f.visible = TRUE;
defines a paint function in a frame that draws a string of characters
near the center of the frame using
show.
