BUG COMBOBOX ?????

[Silvio.Falconi]

I need to have two COMBOBOXes TYPE

local aElemento :={"Testo","Immagine","Barcode"}
local aTipoData :={"Campo","Valore"}
local nvar:=1
local nVar:=2

@ 8, 5 Say "Tipo Elemento " SIZE 80,14 PIXEL OF oDlg TRANSPARENT
@ 8, 75 COMBOBOX aGet[1] VAR nVar1 ITEMS aElemento SIZE 50,90 PIXEL OF oDlg STYLE CBS_DROPDOWN
@ 24, 5 Say "Tipo Dato " SIZE 80,14 PIXEL OF oDlg TRANSPARENT
@ 22, 75 COMBOBOX aGet[2] VAR nVar2 ITEMS aTipoDATA SIZE 50,90 PIXEL OF oDlg STYLE CBS_DROPDOWN

I have always done so I don't understand why now oget_lostfocus makes a error

Code: Select all  Expand view

 Error description: Error BASE/1072  Argument error: <>
   Args:
     [   1] = N   1
     [   2] = C   Testo

what has been changed?


if I change the variable from numeric to text it makes me a strange error example

Code: Select all  Expand view

#include "fivewin.ch"
#include "constant.ch"


Function Test()
       local oDlg,oBar,oFont,oBold
       local nBottom   := 24
       local nRight    := 102
       local nWidth :=  Max( nRight * DLG_CHARPIX_W, 180 )
       local nHeight := nBottom * DLG_CHARPIX_H
       local aGet[17]


       local aElemento :={"Testo","Immagine","Barcode"}
       local aTipoData :={"Campo","Valore"}
       local cDescrizione:=space(40)
       local cItem1    := aElemento[ 1 ]
       local cItem2    := aTipoData[ 1 ]
   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14

   DEFINE DIALOG oDlg        ;
   TITLE "Riga modulo"     ;
   SIZE nWidth, nHeight   PIXEL  FONT oFont    ;
   STYLE nOr( DS_MODALFRAME, WS_POPUP, WS_CAPTION,  4 ) ;
   COLOR CLR_BLACK,  nRgb( 245,244,234)


       @ 8, 5 Say "Tipo Elemento "  SIZE 80,14 PIXEL OF oDlg  TRANSPARENT
       @ 8, 75 COMBOBOX aGet[1] VAR cItem1  ITEMS aElemento  SIZE 50,90 PIXEL OF oDlg    STYLE CBS_DROPDOWN

       @ 24, 5 Say "Tipo Dato "  SIZE 80,14 PIXEL OF oDlg  TRANSPARENT
       @ 22, 75 COMBOBOX aGet[2] VAR cItem2  ITEMS aTipoDATA  SIZE 50,90 PIXEL OF oDlg    STYLE CBS_DROPDOWN

 ACTIVATE DIALOG oDlg CENTERED ;
       ON INIT ( aGet[1]:oGet:SetSel(), aGet[2]:oGet:SetSel())
 RETURN NIL

 

if you play with the two comboboxes, sometimes the word "campo" becomes "campoe"
or the word "barcode" becomes "barcodee"


why don't you fix this bug?

why don't you fix this bug?

If there is a bug, we can fix.
There is no bug in the libs.

You please check your program.

good Mr Linossi teacher of Fwh

Hello Silvio,
you assign a numeric variable to a character.
If you need the numeric, the position in the array you should use aGet[1]:nAt.

@ 8, 75 COMBOBOX aGet[1] VAR cItem1 ITEMS aElemento SIZE 50,90 PIXEL OF oDlg STYLE CBS_DROPDOWN ON CHANGE msginfo( aGet[1]:nAt )

Best regards,
Otto

[Silvio.Falconi]

that is only a sample because numeric test not run ok
now I resolved with
nTipoData:= 1

@ 24, 5 Say "Dato da Stampare" SIZE 90,20 PIXEL OF oDlg TRANSPARENT
@ 22, 75 COMBOBOX aGet[2] VAR nTipoData ITEMS aDataPrint SIZE 50,90 PIXEL OF oDlg;
ON CHANGE ( IIF( nTipoData=2,;
(aGet[3]:hide(),aGet[4]:show(), ;
aGet[4]:setFocus(),;
oBtn1:Hide(),oBtn2:Hide(),oBtn3:Hide()),;
(aGet[4]:hide(),aGet[3]:show(), ;
aGet[3]:setFocus(),;
oBtn1:Show(),oBtn2:Show(),oBtn3:Show() ) ) )

as you can see here

before criticizing myself and continuing to offend me with this gif, carefully read this topic viewtopic.php?f=3&t=38179&p=228031&hilit=+combobox#p228031
and the solution made by Antonino Perricone for combobox control
If Antonino Perricone has created a new class it means that the parent class has problems

[nageswaragunupudi]

the parent class has problems

There are no problems.
You just need to know how to use the class.

I respect you and I don't want to keep fueling discussions with you let's do this I start studying the classes, I just copied an old source of an old program that I didn't do and I recompiled it and it doesn't work with the current version of fwh, there is someone who enjoys modify the object classes to drive us crazy to find the errors and changes made: do I have to list all those classes that over time have been changed for the worse? For example I use a version of the rpreview class but with override comands because the current version has problems and this is not just me but also famous people who are in the breach long before you

Using Combobox:

1) With Numeric Variables:
When using numeric variables, we should NOT use CBS_DROPDOWN style.
Sample:

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oDlg
   local aElemento   :={ "Testo","Immagine","Barcode" }
   local aTipoData   :={ "Campo","Valore"}
   local nvar1       := 1
   local nVar2       := 2
   local aGet[ 2 ]

   DEFINE DIALOG oDlg SIZE 400,200 PIXEL

   @  8,  5 Say "Tipo Elemento " SIZE 80,14 PIXEL OF oDlg
   @  8, 75 COMBOBOX aGet[1] VAR nVar1 ITEMS aElemento SIZE 50,90 PIXEL OF oDlg
   @ 24,  5 Say "Tipo Dato " SIZE 80,14 PIXEL OF oDlg
   @ 22, 75 COMBOBOX aGet[2] VAR nVar2 ITEMS aTipoDATA SIZE 50,90 PIXEL OF oDlg

   ACTIVATE DIALOG oDlg CENTERED

   ? aElemento[ nVar1 ], aTipoData[ nVar2 ]

return nil
 

2)(a) Using Character Variables without CBS_DROPDOWN style.
In this case, user can select one of the options but can not enter a different value manually like in a Get.

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oDlg
   local aElemento   :={ "Testo","Immagine","Barcode" }
   local aTipoData   :={ "Campo","Valore" }
   local cvar1       := "Testo"
   local cVar2       := "Valore"
   local aGet[ 2 ]

   DEFINE DIALOG oDlg SIZE 400,200 PIXEL

   @  8,  5 Say "Tipo Elemento " SIZE 80,14 PIXEL OF oDlg
   @  8, 75 COMBOBOX aGet[1] VAR cVar1 ITEMS aElemento SIZE 50,90 PIXEL OF oDlg
   @ 24,  5 Say "Tipo Dato " SIZE 80,14 PIXEL OF oDlg
   @ 22, 75 COMBOBOX aGet[2] VAR cVar2 ITEMS aTipoDATA SIZE 50,90 PIXEL OF oDlg

   ACTIVATE DIALOG oDlg CENTERED

   ? cVar1, cVar2

return nil
 

2)(b) Using Character Variables with CBS_DROPDOWN style:
In this case, user can select one of the options or enter a different value in the Get.

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oDlg
   local aElemento   :={ "Testo","Immagine","Barcode" }
   local aTipoData   :={ "Campo","Valore" }
   local cvar1       := "Testo"
   local cVar2       := "Valore"
   local aGet[ 2 ]

   DEFINE DIALOG oDlg SIZE 400,200 PIXEL

   @  8,  5 Say "Tipo Elemento " SIZE 80,14 PIXEL OF oDlg
   @  8, 75 COMBOBOX aGet[1] VAR cVar1 ITEMS aElemento SIZE 50,90 PIXEL OF oDlg STYLE CBS_DROPDOWN
   @ 24,  5 Say "Tipo Dato " SIZE 80,14 PIXEL OF oDlg
   @ 22, 75 COMBOBOX aGet[2] VAR cVar2 ITEMS aTipoDATA SIZE 50,90 PIXEL OF oDlg STYLE CBS_DROPDOWN

   ACTIVATE DIALOG oDlg CENTERED

   ? cVar1, cVar2

return nil
 

Please follow these guidelines and you will not get any error.

I allreay resolved see viewtopic.php?f=3&t=39547&p=236024#p236003

Hello Silvio,

Funny I am working right now on a similar program - but for mod harbour.
Same components: Font size, color picker, checkbox, icon selector.

Nages,

my dialog is more complex of your sample







I use nTipoElemento and nTipodata as numeric for the combox

but I take the data from a dbf where I have two field

1. text ( 1CR)
2. Logic

return nil
 

When the nTipoDato=2 it show the get (4) with Memo and you can edit it ,

when nTipoDato=1 it show the normal get but you cannot edit it

then if I press ESC it make error on this lines


@ 22, 130 GET aGet[3] VAR cDesc SIZE 220,12 PIXEL OF oDlg WHEN nTipoDato=1 UPDATE

@ 22, 130 GET aGet[4] VAR cDesc MEMO SIZE 270,30 PIXEL OF oDlg WHEN nTipoDato=2 UPDATE


why I cannet edit the gets? and sometimes I have also oget:lostfocus error I don't Know why
