发帖数: 100 | 1 定义Graphics g
g.drawLine(X1,Y1,X2,Y2)
怎么能对这根直线加粗？在网上找了很久，找到的是用g.setStroke().
但是我加进这个之后，显示错误：the method setStroke is undefined for this
type of graphics. 我在这个中class都
import javax.swing.*;
import java.applet.Applet;
import java.awt.Graphics;
谢谢指教！ |

enable anti-aliasing

发帖数: 82 | 7 It depends. the performance of filling a polygon is better than that of
Java2D with a line stroke > 1. If it's just a horizontal or vertical line
you can use the polygon approach with simple math, although it is not
hard for a line with any slope either.
g.drawPolygon() will respect the antialiasing hint.
