Java 如何复制图片到剪切板呢?
下面是我做的一个软件:
项目源代码见附件
这里面就有"复制图片到剪切板"功能.核心方法如下:
Java代码
- /***
- * 复制图片到剪切板
- * @param image
- */
- public static void setClipboardImage(JFrame frame, final Image image) {
- Transferable trans = new Transferable() {
- @Override
- public Object getTransferData(DataFlavor flavor)
- throws UnsupportedFlavorException, IOException {
- if (isDataFlavorSupported(flavor)) {
- return image;
- }
- throw new UnsupportedFlavorException(flavor);
- }
- @Override
- public DataFlavor[] getTransferDataFlavors() {
- return new DataFlavor[] { DataFlavor.imageFlavor };
- }
- @Override
- public boolean isDataFlavorSupported(DataFlavor flavor) {
- return DataFlavor.imageFlavor.equals(flavor);
- }
- };
- frame.getToolkit().getSystemClipboard().setContents(trans, null);
- }
在JFrame中如何设置图标
方式一:
Java代码
- URL url=this.getClass().getResource("/com/kingbase/img/kingbase_log.PNG");
- // System.out.println(url.getPath());
- ImageIcon icon = new ImageIcon(url);
- frame.setIconImage(icon.getImage());
方式二:
Java代码
- InputStream is = this.getClass().getResourceAsStream(
- "/com/kingbase/img/kingbase_log.PNG");
- BufferedInputStream isr = new BufferedInputStream(is);
- byte[] b = null;
- try
- {
- b = new byte[isr.available()];
- isr.read(b);
- System.out.println(b.length);
- }
- catch (IOException e2)
- {
- e2.printStackTrace();
- }
- if (b != null)
- {
- ImageIcon imageIcon = new ImageIcon(b);
- frame.setIconImage(imageIcon.getImage());
- }
方式三:
Java代码
- InputStream is = this.getClass().getClassLoader().getResourceAsStream(
- "com/kingbase/img/kingbase_log.PNG");前面没有斜杠
- BufferedInputStream isr = new BufferedInputStream(is);
- byte[] b = null;
- try
- {
- b = new byte[isr.available()];
- isr.read(b);
- System.out.println(b.length);
- }
- catch (IOException e2)
- {
- e2.printStackTrace();
- }
- if (b != null)
- {
- ImageIcon imageIcon = new ImageIcon(b);
- frame.setIconImage(imageIcon.getImage());
- }
