Graphics
is an abstract class.
Although many of these methods are abstract, we always use them with objects of a concrete
descendent class of
Graphics
, even though we usually do not know the name of that
concrete class.
public abstract void
drawRect(
int
x,
int
y,
int
width,
int
height)
Draws the outline of the specifi ed rectangle. (
x
,
y
) is the location of the upper-left corner of
the rectangle.
public abstract void
fillRect(
int
x,
int
y,
int
width,
int
height)
Fills the specifi ed rectangle. (
x
,
y
) is the location of the upper-left corner of the rectangle.
public void
draw3DRect(
int
x,
int
y,
int
width,
int
height,
boolean
raised)
Draws the outline of the specifi ed rectangle. (
x
,
y
) is the location of the upper-left corner.The
rectangle is highlighted to look like it has thickness. If
raised
is
true
, the highlight makes
the rectangle appear to stand out from the background. If
raised
is
false
, the highlight makes
the rectangle appear to be sunken into the background.
public void
fill3DRect(
int
x,
int
y,
int
width,
int
height,
boolean
raised)
Fills the rectangle specifi ed by
draw3DRec(x, y,width, height, raised)
public abstract void
drawArc(
int
x,
int
y,
int
width,
int
height,
int
startAngle,
int
arcSweep)
Draws part of an oval that just fi ts into an invisible rectangle described by the fi rst four
arguments. The portion of the oval drawn is given by the last two arguments. See Chapter 18
for details.
public abstract void
drawLine(
int
x1,
int
y1,
int
x2,
int
y2)
Draws a line between points (
x1
,
y1
) and (
x2
,
y2
).
public abstract void
drawOval(
int
x,
int
y,
int
width,
int
height)
Draws the outline of the oval with the smallest enclosing rectangle that has the specifi ed width
and height. The (imagined) rectangle has its upper-left corner located at (
x
,
y
).
