将 jTextPane 文本复制到剪贴板

Question

I have a form which contains a jTextPane and a jButton , I've set the jTextPane Accessible Description to text/html , now I want when I click on the jButton to copy the content of the jTextPane to my clipboard, I tried this code :

 private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        StringSelection stringSelection = new StringSelection (jTextPane1.getText());
        Clipboard clpbrd = Toolkit.getDefaultToolkit ().getSystemClipboard ();
        clpbrd.setContents (stringSelection, null);
    } 

but when I past, it past the text as an HTML format.

How can I solve this probelm ?

First of all, there are 2 clipboards in Java (a local one and a system one, which you are using). Here 's an example that uses the system clipboard. Take a look and try this getClipboardContents method:

public String getClipboardContents(Clipboard clipboard) {
    String result = "";
    if (clipbloard != null){            
        //odd: the Object param of getContents is not currently used
        Transferable contents = clipboard.getContents(null);
        boolean hasTransferableText =
          (contents != null) &&
          contents.isDataFlavorSupported(DataFlavor.stringFlavor);
        if ( hasTransferableText ) {
          try {
            result = (String)contents.getTransferData(DataFlavor.stringFlavor);
          }
          catch (UnsupportedFlavorException ex){
            //highly unlikely since we are using a standard DataFlavor
            System.out.println(ex);
            ex.printStackTrace();
          }
          catch (IOException ex) {
            System.out.println(ex);
            ex.printStackTrace();
          }
        }
    }
    return result;
}

When I use Ctrl+CI get text copied to the clipboard without HTML. You can use the default Action with the following code:

Action copy = new ActionMapAction("Copy", textPane, "copy-to-clipboard");
JButton copyButton = new JButton(copy);

See Action Map Action for more information on how this works.

first you need to select all the text in the textpane and then copy.

private void btnCopyActionPerformed(java.awt.event.ActionEvent evt) {                                        
    textPaneLogs.selectAll();
    textPaneLogs.setFocusable(true);
    textPaneLogs.copy();
}
