How to make text pane accept pastes but block typing

Question

My Goal is : having a text pane where user can paste text only(with OS not a button!!!) and can't type in to the pane

because: can't have submit button (this is a must requirement - I know that it's not logical)

after pasting: the text-pane becomes not editable for user, and the program will change background at specific chars.

after button "clear filed" pressed - the program clears the pane and returns to initial state

My Problem: How to make text pane accept pastes but block typing

so far I made only JPanel with the text pane itself and all the controls will be in different JPanel

public class textPanel extends JPanel{

private JTextPane text;

public textPanel ()
{
    setLayout(new BorderLayout());
    text = new JTextPane();        //12,81
    text.setBorder(BorderFactory.createLoweredBevelBorder());
    add(text,BorderLayout.CENTER);

    StyledDocument doc = text.getStyledDocument();


    setBackground(Color.LIGHT_GRAY);
    setPreferredSize(new Dimension(1000, 210));




}    

thanks for help

Answer 1

Override public void paste() method of your. By default your JTextPane is not editable (setEditable(false)).

The paste() method's source in JTextComponent is

public void paste() {
    if (isEditable() && isEnabled()) {
        invokeAction("paste", TransferHandler.getPasteAction());
    }
}

So you just make it editable, call super.paste(), and set the editable=false back after the super call.
