I have a JEditorPane with text/html and I want an Option to insert (via CTRL + V) text as plain text OR as formatted text. So far the default inserting is working with formatted text. Now I created a class that I can paste the text as plain text. Its mapped to CTRL+V.

My Idea is to map the formatted (standard) inserting to CTRL+SHIFT+V so that I have the option to choose between the two methods

My class for plain text inserting

    class PasteAction extends AbstractAction {

        /**
         * 
         */
        private static final long serialVersionUID = 1L;
        private final JEditorPane textPane;

        public PasteAction(JEditorPane textPane) {
            this.textPane = textPane;
        }

        @Override
        public void actionPerformed(ActionEvent e) {
            try {
                int offset = textPane.getSelectionStart();
                Document sd = textPane.getDocument();
                String value = getClipboard();
                sd.remove(textPane.getSelectionStart(), textPane.getSelectionEnd() - textPane.getSelectionStart());
                textPane.getDocument().insertString(offset, value, null);
                if (value != null) {
                    textPane.setCaretPosition(offset + value.length());
                }
            } catch (Exception exc) {
                exc.printStackTrace();
            }
        }

        public String getClipboard() throws ClassNotFoundException, UnsupportedFlavorException {
            Transferable t = Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null);
            DataFlavor htmlStringFlavor = new DataFlavor("text/plain; class=java.lang.String");
            try {
                if (t != null && t.isDataFlavorSupported(htmlStringFlavor)) {
                    String text = (String) t.getTransferData(htmlStringFlavor);
                    return text;
                }
            } catch (UnsupportedFlavorException | IOException e) {
                e.printStackTrace();
            }
            return null;
        }
    }

Mapping

JEditorPane textareaLogText = new JEditorPane ();
PasteAction pasteAction     = new PasteAction(textareaLogText);                                           // to allow only plaintext to be added
textareaLogText.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_V, ActionEvent.CTRL_MASK), "paste"); // to allow only plaintext to be added
textareaLogText.getActionMap().put("paste", pasteAction);                                                 // to allow only plaintext to be added
textareaLogText.setContentType("text/html");

Any ideas ?

EDIT: Sometimes it is as easy as pie and it is helpful to read the documantation of the JEditorPane.

A simple editorpane.paste(); does the trick.

Below you can find the solution for the search function.

        JEditorPane textareaLogText = new JEditorPane ();
        
        // to allow only plaintext to be added
        PasteAction pasteAction = new PasteAction(textareaLogText);
        InputMap inputMap = textareaLogText.getInputMap(JComponent.WHEN_FOCUSED);
        inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_V, ActionEvent.CTRL_MASK), "pasteUnFormatted");
        textareaLogText.getActionMap().put("pasteUnFormatted", pasteAction);

        // to allow formatted text
        PasteFormattedAction pasteFormattedAction = new PasteFormattedAction(textareaLogText);
        InputMap inputMap2 = textareaLogText.getInputMap(JComponent.WHEN_FOCUSED);
        inputMap2.put(KeyStroke.getKeyStroke(KeyEvent.VK_V, ActionEvent.CTRL_MASK | ActionEvent.SHIFT_MASK), "pasteFormatted");
        textareaLogText.getActionMap().put("pasteFormatted", pasteFormattedAction);

    class PasteFormattedAction extends AbstractAction {
        /**
         * 
         */
        private static final long serialVersionUID = 1L;
        private JTextComponent textComponent;

        public PasteFormattedAction(JTextComponent textComponent) {
            this.textComponent = textComponent;
        }

        @Override

            textComponent.paste();

                int offset = textPane.getSelectionStart();
                Document sd = textPane.getDocument();
                String value = getClipboard();
                sd.remove(textPane.getSelectionStart(), textPane.getSelectionEnd() - textPane.getSelectionStart());
                textPane.getDocument().insertString(offset, value, null);
                if (value != null) {
                    textPane.setCaretPosition(offset + value.length());
                }
            } catch (Exception exc) {
                exc.printStackTrace();
            }
        }
