Como podria hacer esto con xbrowse ?
Posted: Fri Jan 28, 2011 06:13 PM
Hola amigos

Tengo dos DBF'S indexadas por el campo código, una es de clientes, y otra de sus almacenes, (Tienen los mismos campos), y me gustaría que en un xbrowse, al hacer doble click sobre un código, se abra un tree, y me muestre los almacenes de éste cliente.

He hecho pruebas con el ejemplo xbrwtree, pero me lío cuando son dos bases de datos

Code (fw): Select all Collapse
Static function rutasc(oDlg1,oDlg,recibe,aAlias)
local n,conduc:=space(5)
local titulo:="LISTADO DE RUTAS DE CLIENTES"
local oBrw
   if Publicas:abierta=1
      msginfo('Tienes Una ventana Abierta','Atencion')
      return nil
   endif
  dbUseArea(.T.,,Publicas:cUnidad+Publicas:cSubd+"\Almacen",aAlias[23],.T.)
  (aAlias[23])->(OrdSetFocus("Codigo"))
  (aAlias[23])->( dbGotop() )
  dbUseArea(.T.,,Publicas:cUnidad+Publicas:cSubd+"\PROVE",aAlias[21],.T.)
  (aAlias[21])->(OrdSetFocus("Codigo"))
  (aAlias[21])->( dbGotop() )
   SetParent( oDlg1:hWnd, oDlg:hWnd )   
 
   @ 0,0 XBROWSE oBrw ;
     COLUMNS 'Codigo','Nombre','Calle', 'Pobla','Rutar' ;
      SIZE 260,320 PIXEL ;
      COLSIZES ,250,225,200,25 ;      
      JUSTIFY AL_CENTER ;
      OF oDlg1 Alias aAlias[21] FOOTERS AUTOCOLS LINES CELL
      oBrw:aCols[5]:nEditType := 1
      oBrw:bClrSelFocus    := { || { CLR_BLUE, nRGB( 230, 255, 230 ) } }
      oBrw:lColDividerComplete := .f.
      oBrw:nTop    := oDlg1:nTop()
      oBrw:lKineticBrw         := .f.
      oBrw:nBottom := oDlg1:nheight()
      oBrw:nRight  := oDlg1:nWidth()
      oBrw:nStretchCol := STRETCHCOL_LAST
      oBrw:nMarqueeStyle = MARQSTYLE_HIGHLROW
      oBrw:CreateFromCode()
      barra1(oDlg1,oBrw,titulo)
      oBrw:Setfocus()
     
return nil


Esto me muestra en un browse los datos de Prove

Alguna ayuda?

This is a sample using STATES.DBF related to CUSTOMER.DBF in the \fwh\samples folder. Please compile and test this program in the \fwh\samples folder.

In the above sample, the entire data is read into the TreeItem's cargo variable in the memory.

In the next sample, data is NOT read into memory but the DBF is navigated to show the data.
