二、Graphics 绘图常用 API 一、AWT 绘图步骤 在AWT 绘图中 , Canvas 是绘图所在的画布 , Graphics 是绘图使用的画笔 ; AWT 绘图步骤如下 : 首先,自定义 Canvas 组件类 , 重写其中的 Component#paint(Graphics g) 函数 , Component 组件 与 Graphics 是由 paint(Graphics g) 函数 进行关联的 ; ...
public void paint(Graphics g) { Graphics2D g2 = (Graphics2D) g; // The width and height of the canvas int w = getSize().width; int h = getSize().height; // Create an ellipse and use it as the clipping path Ellipse2D e = new Ellipse2D.Float(w/4.0f,h/4.0f, w/2.0f,h/2.0...
