Examples of javax.swing.text.JTextComponent$MutableCaretEvent

javax.swing.text.JTextComponent
Event to use when firing a notification of change to caret position. This is mutable so that the event can be reused since caret events can be fairly high in bandwidth.

        char c = e.getKeyChar();
        
        // as a coding convenience, create a reference to the text component
        // that is typecast to JTextComponent.  this is not essential, as we
        // could typecast every reference, but this makes the code cleaner
        JTextComponent _theComponent = (JTextComponent)DataTypeInteger.this._textComponent;
        String text = _theComponent.getText();
  
        // look for illegal chars
        if ( ! DataTypeInteger.this._isSigned && c == '-') {
          // cannot use '-' when unsigned
          _beepHelper.beep(_theComponent);
