is there a way to tell which arrow has been clicked by the user?

thanks

Only indirectly:

1) Read the value of the control

2) If the event EVENT_VAL_CHANGED occurred, read the value of the control again

3) The new value should be old_value +/- increment_value; from this change it is possible to derive the sign of the increment, i.e. positive or negative; this you can translate to up or down

Hth,

Wolfgang

oh ok i thought i was missing a simpler way to do it.. Thank you wolfgang!

You're welcome.

Note however that the sketch of this indirect method is simplified because it may happen that an event EVENT_VAL_CHANGED is triggered while the numeric value has not changed at all! Hence you might consider supporting my suggestion for an improved behaviour of this event here.
