Thread: jbutton and action event

I want to program a application, when I push the start button, it runs a ffmpeg command to record a online stream, when I push the stop button, I want to send a "q" key to stop the recording. how should I do?

you have to add an actionListener to your button like this:
yourButtonName.addActionListener(new actionListener(){.....});
actionListener is an interface so you have to over write the method actionperformed and add what you want to do with your application (depending on which button user pressed)

I don't thnk Robot willl come into it, isn't ffmpeg a command line app?
