Solución 2
i chicos resolvieron este problema por mí mismo .. Thnks para ur coordinación ..actually que hice el error de dar weightx y de peso al panel de padres que está llevando a cabo el tanto al JList y para el panel JEditor ... brevemente nos deberá configurar los parámetros de ponderación para todos los contenedores primarios que contiene ningún componente que desea cambiar el tamaño ..
Otros consejos
Su lista no conseguirá mucho más grande si usted hace esto:
chooseNamesList.setMaximumSize(new java.awt.Dimension(46, 88));
Si se establece un valor de celda prototipo, el JList no va a cambiar el tamaño cuando se cambian los datos.
Consulte la página Javadoc JList para el método setPrototypeCellValue (objeto).
