Coloque o seu código entre as tags [code], por favor, para facilitar a leitura e te ajudarmos.
Você parece estar usando GridBagLayout. Experimente modificar as restrições (se estiver com o NB em inglês, “constraints”) do JTextField cujo tamanho quer manter fixo. O conselho mais extremo seria parar de usar GridBagLayout e mudar para outro gerenciador de layout.
Esse comportamento que você está descrevendo geralmente acontece quando o text field não possui um número de colunas configuradas.
Especifique um número maior que zero (e sem exageros) de colunas usando o método setColumns que deve resolver.
Obrigado Erick…
A coluna esta com valor 0.
Mudei para 1 e tudo se resolveu…
Thanks…
