标签：boolean java类 操作 事件 etc nts too getc board 4.1 Swing操作方式的Clipboard类位于 java.awt.datatransfer包中，而JavaFX操作方式的Clipboard类位于javafx.scene.input包中。 4.2 如果你在你的Java桌面应用程序中同时使用了Swing和JavaFX技术，建议只使用一种剪切方法，且要保证在对应的事件线程上同步，否则可能会遇到剪切板锁定无法访问的问题。 本文参考了以下文章的内容 5.1 http://blog.csdn.net/shenzhennba/article/details/8213294 5.2 http://cuiweiqing1988.iteye.com/blog/947030 转载于：http://www.alanzeng.cn/2015/10/java-clipboard/ 【转】【Java】剪切板操作大全 标签：boolean java类 操作 事件 etc nts too getc board 原文地址：https://www.cnblogs.com/xiaostudy/p/12909146.html1. 概述
2. Swing的操作方式
2.1 String文本类型
//获取系统剪切板
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
//设置字符串
String str = "测试设置String到剪切板";
//构建String数据类型
StringSelection selection = new StringSelection(str);
//添加文本到系统剪切板
clipboard.setContents(selection, null);
Transferable content = clipboard.getContents(null);//从系统剪切板中获取数据
if (content.isDataFlavorSupported(DataFlavor.stringFlavor)) {//判断是否为文本类型
String text = (String) content.getTransferData(DataFlavor.stringFlavor);//从数据中获取文本值
if (text == null) {
return;
}
System.out.println(text);
}
2.2 Image图像类型
public static void setImageClipboard(Image image) {
ImageSelection imgSel = new ImageSelection(image);
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(imgSel, null);
}
public static class ImageSelection implements Transferable {
private Image image;
public ImageSelection(Image image) {this.image = image;}
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[]{DataFlavor.imageFlavor};
}
public boolean isDataFlavorSupported(DataFlavor flavor) {
return DataFlavor.imageFlavor.equals(flavor);
}
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (!DataFlavor.imageFlavor.equals(flavor)) {throw new UnsupportedFlavorException(flavor);}
return image;
}
}
public static Image getImageClipboard() {
Transferable t = Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null);
try {
if (null != t && t.isDataFlavorSupported(DataFlavor.imageFlavor)) {
Image image = (Image)t.getTransferData(DataFlavor.imageFlavor);
return image;
}
} catch (UnsupportedFlavorException e) {
//System.out.println("Error tip: "+e.getMessage());
} catch (IOException e) {
//System.out.println("Error tip: "+e.getMessage());
}
return null;
}
2.3 自定义剪切板
public class TestSelection implements Transferable, ClipboardOwner {
public static final DataFlavor rangeFlavor = new DataFlavor(RangeDataModel.class, "Report Range");//class为自定义的java类 字串随便
private static final DataFlavor[] flavors = { rangeFlavor };
private Object data;
public TestSelection(Object data) {
this.data = data;
}
@Override
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (flavor.equals(flavors[RANGE])) {
return data;
} else {
throw new UnsupportedFlavorException(flavor);
}
}
@Override
public DataFlavor[] getTransferDataFlavors() {
return (DataFlavor[]) flavors.clone();
}
@Override
public boolean isDataFlavorSupported(DataFlavor flavor) {
for (int i = 0; i ) {
if (flavor.equals(flavors[i])) {
return true;
}
}
return false;
}
@Override
public void lostOwnership(Clipboard clipboard, Transferable contents) {
// TODO Auto-generated method stub
}
}
//创建自定义剪切板对象
Clipboard clipboard = new Clipboard("clipboardName");
//构建数据对象 data为数据类型java类的对象
ReportSelection content = new ReportSelection(data);
clipboard.setContents(content, null);
//注意：自定义剪切板必须给null参数
Transferable content = clipboard.getContents(null);
if (content.isDataFlavorSupported(ReportSelection.rangeFlavor)) {
RangeDataModel data = (RangeDataModel) content.getTransferData(ReportSelection.rangeFlavor);
System.out.println(data);
}
3. JavaFX的操作方式
Clipboard clipboard = Clipboard.getSystemClipboard();
ClipboardContent cc = new ClipboardContent();
cc.putString("测试使用JavaFX向系统剪切板放置数据");
clipboard.setContent(cc);
Clipboard clipboard = Clipboard.getSystemClipboard();
clipboard.getContent(DataFormat.PLAIN_TEXT);
