Tlist con Xbrowse

[audisys]

Alguien por curiosidad tiene la Clase Tlist de Manuel Exposito, mejorada para que trabaje con Xbrowse, no he podido hacer funcionar con el Xbrowse de la 8.04. El Metodo Setarray no sincroniza bien con el Xbrowse.


Mil Gracias,

[Antonio Linares]

José,

Puedes mostrarnos la parte del código PRG en donde llamas al método SetArray() ? gracias

[audisys]

Antonio este el codigo del llamado al xbrowse

REDEFINE XBROWSE ::oLbxBody ID 600 OF oDlg ;

::oLbxBody:bKeyDown := {|nKey,nFlags|::LeeTecla(nKey,nFlags,oList,lView),Eval(bChanBrw)}
oList:SetBrowse(::oLbxBody)

Siempre me muestra el primer elemento.

Adjunto la clase Tlist que estoy usando.

José,

Prueba así:

Code: Select all

 REDEFINE XBROWSE ::oLbxBody ID 600 OF oDlg ; 
      FIELDS oList:Pos ,;
         oList:Current[1] ,;
         oList:Current[2] ,;
         oList:Current[3] ,;
         oList:Current[4] ,;
         oList:Current[5] ,;
         oList:Current[6] ,;
         Round((oList:Current[3]*oList:Current[4]),0) ;
      HEADERS "No","Código","Descripción del Producto","Cantidad","Vlr.Unitario" ,;
      "% Desc","% Iva","Subtotal" ;
      PICTURES "999", nil, nil,"@Z 9999,999.99","@Z 9999,999,999.99","@Z 999.99","@Z 999.99", ;
      "@Z 9999,999,999" ;
      COLSIZES 27,90,140,70,90,40,40,90 ;
// JUSTIFY no es necesario. TXBrowse justifica automaticamente basándose en el tipo de datos
// No es necesario usar Transform(). Puedes usar la claúsula PICTURE si te hace falta

oList:SetBrowse( ::oLbxBody )
ACTIVATE DIALOG oDlg CENTERED

Modifica la Clase TList método SetBrowse() de esta forma:

Code: Select all

if upper( oBrw:ClassName() ) $ "TXBROWSE" // De WINDOWS

   oBrw:bGoTop       := { || ::GoTop() }
   oBrw:bGoBottom    := { || ::GoBottom() }
   oBrw:bBof         := { || ::BoA }
   oBrw:bEof         := { || ::EoA }
   oBrw:bSkip        := { |n| ::Skipper( If( n == nil, 1, n ) ) }
   oBrw:bKeyCount    := { || Len( ::aList ) }
   oBrw:bKeyNo       := ;
   oBrw:bBookMark    := { |n| If( n == nil, ::pos, ::pos := n ) }

   oBrw:nDataType    := 3

Endif
