I did not understand why if I have a get control to which I change the value, it does not execute the "On change" command
to execute this command I have to add EVAL (aGet [1]: bchange)

sample :

DEFINE DIALOG oDlg SIZE 400,200 Title "test date,valid"

@ 12,5 SAY "Dal :" OF oDlg PIXEL SIZE 100,20 TRANSPARENT

@ 10,35 GET aGet[1] VAR dDataIniziale SIZE 100,12 PIXEL OF oDlg ;
BITMAP ".\bitmaps\cal.bmp" ;
ACTION (dDataIniziale:= XbrGetDate(txt_to_date( dDataIniziale) , "Select a date",dStagioneMin,dStagioneMax, .t., 0.6, ,aGet[1] ),;
IIF( dDataIniziale=ctod("") .or. dDataIniziale=nil ,;
(dDataIniziale:="Select a date",aGet[1]:CTEXT(date_to_txt(dDataIniziale))),;
aGet[1]:CTEXT(date_to_txt(dDataIniziale)) ) ,;
aGet[1]:refresh(),EVAL( aGet[1]:bchange)) ;
VALID ValidareData(txt_to_date(dDataIniziale),txt_to_date( dDataFinale) ) ;
ON CHANGE ( dtemp1:= txt_to_date( dDataIniziale),;
dtemp2:= txt_to_date( dDataFinale) ,;
dDataIniApp:=dtemp1,;
dDataFinApp:=dtemp2,;
CHANGE_PLAN( dDataIniApp,dDataFinApp,lShowNumeri,lshowPagamenti) )

If I not insert EVAL( aGet[1]:bchange) the get not execute the command ON CHANGE why ?

Try:

ON CHANGE( My_Function(... ) )

Posted: **Wed Apr 08, 2020 10:28 pm**

karinha,

allready tried
static dDataIniApp,dDataFinApp,lShowNumeri,lshowPagamenti //because are DATA variables

ON CHANGE ( MyFunction(dDataIniziale,dDataFinale) )

Function MyFunction(dDataIniziale,dDataFinale)
local dtemp1:= txt_to_date( dDataIniziale)
local dtemp2:= txt_to_date( dDataFinale)

dDataIniApp:=dtemp1
dDataFinApp:=dtemp2

CHANGE_PLAN( dDataIniApp,dDataFinApp,lShowNumeri,lshowPagamenti)

return nil

it need only EVAL( aGet[2]:bchange) otherwise it does not bchange

I tried also with

aGet[1]:bchange := { || MyFunction(dDataIniziale,dDataFinale) }
aGet[2]:bchange := { || MyFunction(dDataIniziale,dDataFinale) }

not run

Don't you have to refresh() the object?

Posted: **Thu Apr 09, 2020 12:01 am**

the problem is not refresh the get but assign the new values on dDataIniApp and dDataFinApp are two data of Tapplication()

Hola buenos dias,
Sigue habiendo problemas con el ON CHANGE del Método TGET, como se puede solucionar?

Ejemplo:

Code: Select all

REDEFINE GET oGet1 VAR mGET1 ID 11     OF oDlg ON CHANGE (mGET2:=mGET1+10,oGet2:Refresh())
REDEFINE GET oGet2 VAR mGET2 ID 12     OF oDlg

No se actualiza el valor del segundo get (oGet2)

Muchas gracias...
