Dear all,

what is a good way to implement a textbox that can only receive number?
when I tried to implement it using text_updated event
it runs so slow that it disturb overall process (my menu stop working)
or even better, what method to overwrite in wxtextctrl class to achieve

The best way is to use Validators. There's a pre-built one for
controlling numerics:,
  :validator => )

I tried filter_numeric before
and found out if it only filter input, not realy confirm if the number
I try to workaround a bit using key_update event
and filter some more key like + - , . e
well, it works well, the trick is to use* change_value*, not *set_value*
somehow, when I try to add humanizing number function, I got stuck
(humanizing = 10000 -> 10,000)
because I cannot move my cursor / insert point to the last of textctrl
and *set_insertion_point_end* does not seem to work
is there a way to fix this?
