[RESOLVIDO] Netbeans 8.2 nao deixa criar um evento Action Performed para um icone

Jefferson_Andre_da_1 · Novembro 5, 2018, 9:08pm

Saudações,

Estou seguindo as aulas do prof., Jose Assis e a opcao btnUsuReadActionPerformed nao aparece ao clicar com o botao direito em cima do icone.

Sera que pulei alguma etapa ou esta opcao ficou obsoleta neste netbeans ? E se ficou como proceder para ao clicar no icone fazer uma procura no Mysql ?

Segue a tela que nao esta permitindo fazer isso e obrigado pela atencao
