I tried to write a very simple layout that shows how you can intercept left and right and map next_game and prev_game. Here there's a signal callback function that basically shifts the games in the opposite direction with respect to what you press (so right = previous game, left = next game).
fe.add_text ("[Title]",0,0,fe.layout.width,fe.layout.width*0.05)
fe.add_signal_handler( this, "on_signal" )
function on_signal( sig ){
if (sig == "left") {
fe.signal ("next_game")
return true
}
if (sig == "right"){
fe.signal ("prev_game")
return true
}
return false
}
