[BUG] Repeating input-value not possible when holding max value

[jakobjung10]

there are no new joystick events generated when you hold the maximum value of the joystick (e.g. -1.0 or 1.0).
i.e. when holding up or down or left or right at their respective extreme positions, no events are generated after the first event.

code: Qt-example in the README
Hardware: SteamDeck with Ubuntu

That is how the sdl2 library works. There is no new action, so there isn't a new event. You need to implement your own repeat or you can look at the button_repeater.py file in the pyjoystick library. I believe I use a thread to check how much time has passed to implement a repeat action. I only have classes for a normal button or the hat button type.

Thank you, @justengel, for the response,

what's the easiest approach in your opinion?
I don't want to mess around with the internals of the library, if avoidable.
I don't see how subclassing a new Repeater will solve the problem yet.
Could you maybe guide me into the right direction?

BR,
Jakob

I think this would work. It has been a long time.

from pyjoystick import Repeater

class AxisRepeater(Repeater):
    def start_repeat(self, key):
        """Start a key repeating."""
        if key.keytype == key.AXIS:
            Repeater.start_repeat(self, key)


repeater= AxisRepeater(
    first_repeat_timeout=0.5, 
    repeat_timeout=0.03, 
    check_timeout=0.01
)

mngr = pyjoystick.ThreadEventManager(
    event_loop=run_event_loop,
    handle_key_event=handle_key_event,
    button_repeater=repeater
)
mngr.start()


# do stuff to keep the event manager running

If you aren't using the thread event manager then you can use.

def handle_key_event(key):
    pass  # Do something with the key

repeater = AxisRepeater(
    first_repeat_timeout=0.5, 
    repeat_timeout=0.03, 
    check_timeout=0.01,
    key_repeated=handle_key_event,  # function called when key is repeated
)
repeater.start()  # start the thread

def key_received(key):
    repeater.start_repeat(key)
    handle_key_event(key)

run_event_loop(print_add, print_remove, key_received)
