set spinner on combobox

[Silvio.Falconi]

when the user change the second combobox , the procedure must change the value of the tget

Code: Select all  Expand view

      @ 480,630 COMBOBOX oCbx3 Var cFormazione ITEMS aFormazione ;
             SIZE 120,70 PIXEL OF oDlg HEIGHTGET 18
       @ 510,630 COMBOBOX oCbx4 Var cCalcolo ITEMS aCalcolo ;
             SIZE 120,70 PIXEL OF oDlg HEIGHTGET 18 ;
             ON CHANGE ( [b]ResetValore[/b](oCbx3:nAt,oCbx4:nAt, @nValore,aGet) )
       @ 540,630 GET aGet[8] var nValore SIZE 100,20 PIXEL RIGHT OF oDlg  SPINNER MIN 1 MAX 90



Function ResetValore(nForma,nMetodo, nValore,oControls)

     IF nForma= 1 .and. nMetodo= 3
        nValore:= 3
     *  oControls[8]:bMin := 3

     elseif nForma= 2 .and. nMetodo= 3
        nValore:= 6
       * oControls[8]:bMin := 6
        Endif
         oControls[8]:refresh()
   return nil

How I can to set MIN and MAX ? ( I must change only the value of MIN
I tried with oControls[8]:bMin := 3 and make error

Mire en \samples\XBRCALEN.PRG si le ayuda. No entiendo muy bien lo que quieres hacer. Un ejemplo completo siempre es bienvenido para las críticas.

in fact I understood that you did not understand
Is simple
if the first combo is 1 and the second is 3 the value in the get must be 3 as the min value and 90 as the max
if the first combo is 2 and the second is 3 the value in the get must be 6 as the min value and 90 as the max

here is a little test, obviously it changes the value of the get but if the user presses the spinner he could put the value 1 instead of three or six
I wanted to block the minimum value

hi Silvio,

i would try aGet[8]:bMin

Code: Select all  Expand view

METHOD Spinner( bUp, bDown, bMin, bMax ) CLASS TGet

   If ::lReadOnly
      return nil
   Endif

   ::bMin := bMin
   ::bMax := bMax

No not run

if the user changes the value back to 1 when the minimum is 3 or 6 the procedure could crash because I'll explain for example if we analyze the sequences
1-2 adds up to 3 this when it comes to sequences with two numbers
1-2-3 the minimum sum is 6 this when it concerns the sequences with three numbers
if the user changes and puts 1 the procedure will never be able to create an array in which the summed sequences make 1 and therefore could crash the program making an error
I think I have explained the problem well

Thanks I had already tried ... but there is a problem !! If the procedure tells the tget that bMin: = {|| nValue}, changes the value ok. if the user increases and then decreases it does not return to the minimum number

perhaps with a video I try to understand the problem



ie if the user presses the down arrow he cannot decrease the value

the user can initially decrease or increase the value in the get by pressing the spinner buttons,

once the ResetValore() function has set the minimum value the user can only increase the value, and cannot return back
