Ola Pessoal,
Estou com problemas para implementar um GlassPanel dentro de Internal
Frames:
1. O GlassPanel (no qual estou desenhando um circulo vermelho) nao aparece dentro do
InternalFrame
quando a janela em questao esta selecionada, somente quando seleciono/ativo outra
janela eh que o
glasspanel pode ser visualizado. Nao acredito que seja bug, pois o metodo paint do
GlassPanel nao
eh chamado quanto a janela encontrasse selecionada. Provavelmente eh algum setup
necessario ao
JDesktop, porem nao o encontrei nenhuma referencia na documentacao da sun. Por favo se
alguem ja
tiver encontrado alguma solucao para este problema me responda.
ps: seguem um exemplo que fiz com o problema. (desculpem o spawn na
lista)
Obrigado.
Luciano da Silva Ribas
