Swing Designer doesn't render a window that contains JTextFieldLimit object.

Have you you tried <JTextFieldLimit class> with Swing Designer? Swing Designer doesn't render a window that contains JTextFieldLimit object.

I have never heard of that class, and it does not appear to be part of the JDK.

With out a complete test case and your log file, I couldn't even begin to guess at what the issue might be.

JTextFieldLimit Class look like this

Code: Select all

import javax.swing.*;
import javax.swing.text.*;

public class JTextFieldLimit extends PlainDocument {
  private int limit;
  // optional uppercase conversion
  private boolean toUppercase = false;
 
  JTextFieldLimit(int limit) {
   super();
   this.limit = limit;
   }
   
  JTextFieldLimit(int limit, boolean upper) {
   super();
   this.limit = limit;
   toUppercase = upper;
   }

  public void insertString
    (int offset, String  str, AttributeSet attr)
      throws BadLocationException {
   if (str == null) return;

   if ((getLength() + str.length()) <= limit) {
     if (toUppercase) str = str.toUpperCase();
     super.insertString(offset, str, attr);
     }
   }
}


and this class is used like this

Code: Select all

textField = new JTextField();
textField.setDocument(new JTextFieldLimit(10));

And here's log file in .metadata/.log
