Swing text组件无法从剪贴板粘贴大型文本数据:java.io.IOException:所有者无法转换数据
我直接使用JTextArea,并通过JTextComponent接口尝试将基于swing的应用程序(记事本)外部的文本数据粘贴到应用程序中 使用两种不同的方法(如下所示),对于大量文本数据,我似乎得到了相同的结果。只要我坚持少量(java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76))就行 at>java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:87) 在java.awt.EventQueue$4.run(EventQueue.java:708) 在java.awt.EventQueue$4.run(EventQueue.java:706) 位于java.security.AccessController.doPrivileged(本机方法) at>java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) 位于java.awt.EventQueue.dispatchEvent(EventQueue.java:705) 位于java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) 在java.awt.EventDispatchThread.PumpeEventsforFilter(EventDispatchThread.java:161) 位于java.awt.EventDispatchThread.PumpeEventsforHierarchy(EventDispatchThread.java:150) 位于java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) 位于java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) 在java.awt.EventDispatchThread.run(EventDispatchThread.java:91) ==更新==Swing text组件无法从剪贴板粘贴大型文本数据:java.io.IOException:所有者无法转换数据,java,swing,exception,jtextarea,ioexception,Java,Swing,Exception,Jtextarea,Ioexception,我直接使用JTextArea,并通过JTextComponent接口尝试将基于swing的应用程序(记事本)外部的文本数据粘贴到应用程序中 使用两种不同的方法(如下所示),对于大量文本数据,我似乎得到了相同的结果。只要我坚持少量(java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76))就行 at>java.security.ProtectionDomain$1.doIntersectio
额外的测试似乎表明,这只发生在Linux操作系统(我用于开发)上,但它似乎在windows上运行(我不使用)。不知道它是否能更好地处理大数据,但您可以尝试使用DefaultEditorKit中的默认操作进行复制:
JButton paste = new JButton( new DefaultEditorKit.PasteAction() );
该操作也可以添加到JMenuItem。它实际上没有,但感谢您的建议。
Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable t = c.getContents(this);
if (t == null)
return;
try {
component.setText((String) t.getTransferData(DataFlavor.stringFlavor));
} catch (Exception e){
e.printStackTrace();
}
