Problema con ActionListener en ventana en segundo plano

Publicado por Alejandro (19 intervenciones) el 22/11/2019 17:48:56
  • Alejandro se encuentra ahora conectado en el
  • chat de PHP
Tengo un JFrame que implementa ActionListener y una clase que extiende ActionEvent para generar los eventos.
El programa reacciona a los eventos mientras la ventana tenga el Foco, si cambio de ventana el programa deja de responder a los eventos. Yo necesito que aunque la ventana este minimizada responda a los eventos.
Cualquier ayuda es bienvenida, gracias.
