XBROWSE CheckBOX SelectALL

[shri_fwh]

Dear Rao Sir ,

I have tried to use CheckBox in XBROWSE and its working checks and un-checks BUT it is NOT working for SelectAll method.

The Code is given below. Could you please guide me

Code: Select all  Expand view

#include "fivewin.ch"

function Main

   local oDlg, oBrw, aData
   local oCn := FW_DemoDB( 1 )
   local oRs

   oRs := oCn:RowSet( "select * from clients" )


   DEFINE DIALOG oDlg SIZE 400,400 PIXEL TRUEPIXEL

   @ 20,20 XBROWSE oBrw SIZE -20,-20 PIXEL OF oDlg ;
      DATASOURCE oRs  ;
      COLUMNS "Code", "First", "Last" ;
      LINES NOBORDER




    WITH OBJECT oBrw:InsCol( 1 )

      :cHeader       := " "
      :bEditValue    := { || If( AScan( oBrw:aSelected, oBrw:BookMark ) > 0, .t., nil ) }
      :SetCheck()
      :nHeadBmpNo    := { || If( Len( oBrw:aSelected ) == oBrw:nLen, 1, 2 ) }
      :bLClickHeader := < |r,c,f,oCol|



                            If  Len( oBrw:aSelected ) == oBrw:nLen
                                oBrw:SelectNone()
                            else
                                oBrw:SelectAll()
                                ?"Select All"
                            endif


                            return nil
                        >

   END


   WITH OBJECT oBrw
      :nMarqueeStyle    := MARQSTYLE_HIGHLROW
      :lMultiSelect     := .f.
      :bClrSelFocus     := { || { CLR_BLACK, CLR_HGRAY } }
      :nStretchCol      := 3
      :aCols[ 1 ]:bClrSelFocus := { ||{  CLR_BLACK, CLR_WHITE } }
      :bLClicked        := { |r,c,f,oBrw| If( oBrw:MouseColPos( c ) == 1 , ;
                           If( ( f := AScan( oBrw:aSelected, oBrw:BookMark ) ) == 0, ;
                           AAdd( oBrw:aSelected, oBrw:BookMark ), ;
                           ADel( oBrw:aSelected, f, .t. ) ), nil ), ;
                           oBrw:RefreshCurrent() }
      :CreateFromCode()
   END




   ACTIVATE DIALOG oDlg CENTERED

return nil

 

Thanks

We recommend this approach for users with recent versions of FWH

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oCn, oRs
   local oDlg, oBrw, oFont

   oCn   := FW_DemoDB()
   oRs   := oCn:Customer

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
   DEFINE DIALOG oDlg SIZE 700,600 PIXEL TRUEPIXEL FONT oFont

   @ 20,20 XBROWSE oBrw SIZE -20,-20 PIXEL OF oDlg ;
      DATASOURCE oRs ;
      COLUMNS  {|| oBrw:IsSelectedRow() }, "FIRST", "CITY", "SALARY" ;
      HEADERS  " " ;
      COLSIZES "9999" ;
      CELL LINES FOOTERS NOBORDER

   WITH OBJECT oBrw
      WITH OBJECT :aCols[ 1 ]
         :SetCheck()
         :bFooter       := { || Len( oBrw:aSelected ) }
         :nHeadBmpNo    := { || If( Len( oBrw:aSelected ) == oBrw:nLen, 1, 2 ) }
         :bLClickHeader := { || oBrw:SelectRow( If( Len( oBrw:aSelected ) < oBrw:nLen, 4, 0 ) ), ;
                                oBrw:Refresh() }
      END
      WITH OBJECT :Salary
         :nFooterType   := AGGR_SUM
         :bSumCondition := { || oBrw:IsSelectedRow() }
      END
      :bLDblClick := { || oBrw:SelectRow() }
      :bKeyChar   := { |k| If( k == 32, ( oBrw:SelectRow(), 0 ), nil ) }
      :bClrStd    := { || { CLR_BLACK, If( oBrw:IsSelectedRow(), CLR_HGREEN, CLR_WHITE ) } }
      //
      :MakeTotals()
      :CreateFromCode()
   END

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

   oRs:Close()
   oCn:Close()

return nil
 

I have provided to toggle selection with double click and pressing space key. You can change it as you like.
Generally try to avoid toggling on single click, because single click is meant for repositioning the row,

This sample also demonstrates automatic recalculation of footers and refreshing without any extra code. Please also note that the sum of salary column is a conditional sum of selected rows only.

Dear Sir ,

Many thanks for this example and providing tips on the conditional sum.

Thanks
