SWT x EU --> variavel

Bom dia galera!!!

estou iniciando em java agora, e pra estudar estou montando uma agenda pessoal em java/swt , com o visual editor do eclipse.

gostaria que me ajudassem num problema, mais que ainda não resolvi…

estou criando um botão, na toolbar assim:

e tipo essa variável btExcluir somente funciona dentro dessa função, quando coloco dentro de um listener da tabela, pra quando a pessoa clicar em cima da tabela ela habilitar o o botão.

quando uso ela assim:

esse código ai acima está dentro de outra função , inicializada assim:

Me desculpe a extenção do tópico, mas já tentei de tudo e não consegui. Obrigado!
