| rectbutton |
(Number x, Number y, Number width, Number height [, double border [, int state]]) |
|
| |
Transforms
rect,
or the rectangle that has
(x, y)
as its upper left corner and
width
and
height
as its dimensions, using
CTM
and then fills the resulting path on
drawable
by painting its interior using
foreground.
If the optional
border
argument is positive then it is used as the width of a border that is drawn along
the interior edges of the rectangle with the four pieces of the border shaded so
the rectangle looks like a raised button when
state
is zero (the default) or a lowered (i.e., pressed) button when
state
is non-zero.
Right now the interpretation of "raised" and "lowered" gets muddled in rotated
coordinate systems.
rectbutton
makes no use of or changes to the current
path.

| Example: |
The program,
import yoix.*.*;
JFrame f = {
Color background = Color.black;
Rectangle button = {
double x = 144;
double y = 144;
double width = 144;
double height = 72.0;
};
int pressed = 0;
paint(Rectangle r) {
graphics { // "named block"
gsave();
setgray(0.8);
rectbutton(button, 72/16, pressed);
grestore();
}
}
mousePressed(e) {
if (pointInRect(e.coordinates, button)) {
pressed = 1;
repaint();
}
}
mouseReleased(e) {
if (pressed) {
pressed = 0;
repaint();
}
}
};
f.visible = TRUE;
defines a paint function that draws a button with a small border that
reacts when you press a mouse button when the cursor is in the button.
