不可编辑时，将插入符号保留在TextArea中

Question

I'm using java, and I'm trying to make a JTextArea that is non-editable but still has the caret in the field. In other words, a Text Area that does not display characters typed by the user, but still has the blinking caret (ie focus).

I honestly stumped on this problem. I've tried mucking around with setEditable , but theres no way to keep the caret. I've also tried deleting the character the user enters as soon as they type it, but i can't stop it flashing on the screen.

Answer 1

I think the following will help you:

textArea.getCaret().setVisible(true);

or

textArea.getCaret().setSelectionVisible(true);

Answer 2

As for the answers above

textArea.getCaret().setVisible(true);

does not always work perfectly, if the TextArea or EditorPane loses focus, say you click on a different frame or something, when you come back the cursor will be invisible again.

I have had the same issues, it appears the solution is to add a focus listener and set it visible every time the editor gains focus.

text.addFocusListener(new FocusAdapter() {
  @Override
  public void focusGained(FocusEvent e) {
    text.getCaret().setVisible(true); // show the caret anyway
  }
});
