在Swing的面板中,我使用paintComponent使用Graphics2D绘制具有不同坐标的字符串:
g2.drawString("one", 0, 0);
g2.drawString("two", 50, 50);
有没有一种方法可以将多个结果图纸组合成一个drawString?
编辑:我基本上使用unicode字符绘制一个音乐梯级,我想绘制另一个梯级。我希望会有一种干净的方法来复制它。
最佳答案
样例代码。
private BufferedImage sample; //declare as class member to reuse instance
@Override
protected void paintComponent(Graphics g) {
if (sample == null) { // lazy initialization, but you could do it even in constructor
sample = new BufferedImage(sampleWidth, sampleHeight, bufferedImage.TYPE_INT_ARGB);
Graphics2D g2d = sample.createGraphics();
g2d.setColor(Color.WHITE);
g2d.fillRect(0, 0, sampleWidth, sampleHeight);
g2d.setColor(Color.BLACK);
g2d.drawString("Some text", 10, 10);
g2d.drawWhateverYouNeed(....);
}
g.setColor(getBackground());
g.fillRect(0, 0, getWidth(), getHeight());
// draw sample image three times, in sequence
for (int i = 0; i < 3; i++) {
g.drawImage(sample, 0, i * sampleHeight, this);
}
}
