我使用paintComponent()
画在的backgound动画图像的GIF JPanel
。 它显示了GIF,但不动画。 我用Java 1.5的,我知道,我可以使用标签与图标。
是否有任何身体知道为什么,以及如何解决它?
private static class CirclePanel extends JPanel {
ImageIcon imageIcon = new ImageIcon(BarcodeModel.class.getResource("verify.gif"));
Point point = f.getLocation();
protected void paintComponent(Graphics g) {
Graphics gc = g.create();
Graphics2D g2d = (Graphics2D) g.create();
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.3f));
g2d.setColor(Color.BLUE);
g2d.drawImage(imageIcon.getImage(), getWidth() / 2, getHeight() / 2, null);
g2d.drawRect(0, 0, getWidth(), getHeight());
g2d.setStroke(new BasicStroke(10f,BasicStroke.CAP_ROUND,BasicStroke.JOIN_MITER));
g2d.setFont(g.getFont().deriveFont(Font.BOLD | Font.ITALIC,15f));
g2d.drawString("Wait Please ...",getWidth()/2-imageIcon.getIconHeight()/3,getHeight()/2+imageIcon.getIconHeight()+15);
g2d.dispose();
}
这是GIF图像。
编辑:只需添加图像观测到g2d.drawImage()方法。
g2d.drawImage(imageIcon.getImage(), getWidth() / 2, getHeight() / 2, this);
