Multi Group Purge With Menu

You can’t use the purge code within a function. You’ll need a different trick for that but you’d simply use your purge code inside your menu callbacks (including previous and next buttons).

Check this old post for more info on next/prev menu buttons: click here

Thanks. I did add the code as you said. It works but now the menu only cycles 1-20 and not 1-40 using the Prev + Next buttons.

The link to the old post didn't work. I'll have a search.

I don't know why the link wasn't attached.

Anyway, here's a quick example of what you're looking for:

on init

declare ui_menu $my_menu

make_persistent($my_menu)

declare $i

$i := 0

while ($i<10)

add_menu_item($my_menu,$i+1,$i)

inc($i)

end while

declare ui_button $prev

declare ui_button $next

end on
 
on ui_control($next)

if ($my_menu<(10-1))

set_control_par(get_ui_id($my_menu),$CONTROL_PAR_VALUE,$my_menu+1)

end if

set_control_par(get_ui_id($next),$CONTROL_PAR_VALUE,0)

end on

on ui_control($prev)

if ($my_menu>0)

set_control_par(get_ui_id($my_menu),$CONTROL_PAR_VALUE,$my_menu-1)

end if

set_control_par(get_ui_id($prev),$CONTROL_PAR_VALUE,0)

end on

Thanks a lot. I did post yesterday to say I had found the answer. Not sure why it hasn't added to the discussion. Maybe my PC had a moment.

I'm all sorted now thanks to you folks.
