Antonio,

Do you mean using FWH own Class TCBrowse ?

[AHF]

Yes.

AHF,

The below info is from my notes file. Note that you have indexes, filters, and deleted records to handle, so the solution has to consider these.

James

---------------------------------
8/24/2007 Update: Antonio posted this one.

oBrw:nClrPane := { || If( OrdKeyNo() % 2 == 0, RGB( 230, 230, 230), RGB( 190, 215, 190 ) ) }
----------------------

This is a much better one, but only for objects. Unfortunately dbskip() only returns nil so you can't do this without a database object. [Update: There is an undocumented function _dbskipper() that does return the number of records skipped, so perhaps this could be done without a database object.]

lClrFlag:=.f.

oLbx:bSkip:={| nRecs | (nRecs:= ::oInvmast:skipper( nRecs ), lClrFlag:=if(nRecs/2 = int(nRecs/2), lClrFlag,!lClrFlag), nRecs) }

oLbx:nClrPane := { || if(lClrFlag, rgb(255,255,235), rgb(192,208,179)) }

The above works with or without indexes, filters, and deleted records.

// end

James,

Thanks.

AHF,

here is another working solution

Code: Select all

...
::oBrw:bBkColor := {|nRow,nCol,nStyle| TcBrwCol (nRow,nStyle,::oBrw,  aColorK) }
...

FUNCTION TcBrwCol ( nRow, nStyle, oBrw, aColor )

LOCAL nColor

DEFAULT aColor := {RGB( 102, 205, 170 ),RGB( 32, 178, 170 )}

//IF nStyle = 0
   IF IsEven( nRow )
      nColor := aColor[1]
   ELSE
      nColor := aColor[2]
   ENDIF
//ENDIF

RETURN ( nColor )


FUNCTION IsEven( nVal )
RETURN IIF( nVal = Round( nVal/2, 0 )*2, .T., .F. )

Problem solved. Thanks for your help.

Hello,

I return to same problem because using OrdKeyNo in a network the application is crawling. Without it it works great!. However the users are claiming for a 2 colors lines.
How can I solve it ?

Any ideas ?

Antonio

AHF,

There are two solutions above that don't use OrdKeyNo(), have you tried them?

James

[AHF]

James,

Yes.
The problem with those solutions is when you begin to skip over the last visible line of the browse (line by line) you always get the smae rownr and it stops working.
It only works when you repaint all the browse. (pg up or down)

I have never had that problem. Can we see the code you are using?

AHF,

Below is a working example. Use it with the fw\samples\customer.dbf file.

Regards,
James

Code: Select all

// Purpose : Sample TCBrowse with alternating color rows
// Author  : James Bott
// Date    : 1/9/2008

#include "fivewin.ch"
#include "TCBrowse.ch"    // <-- Important

function main()
   local oWnd, oCustomer, oBrw, lClrFlag

   use customer
   database oCustomer

   define window oWnd title "TCBrowse Test"

   @ 0,0 browse oBrw of oWnd update

   oBrw:setoDBF( oCustomer )
   oBrw:cAlias := oCustomer:cAlias // required

   add column to browse oBrw field first

   add column to browse oBrw field last

   lClrFlag:=.f.

   oBrw:bSkip:={| nRecs | (nRecs:= oCustomer:skipper( nRecs ), lClrFlag:=if(nRecs/2 = int(nRecs/2), lClrFlag,!lClrFlag), nRecs) }

   oBrw:nClrPane := { || if(lClrFlag, rgb(255,255,235), rgb(192,208,179)) }

   oWnd:oClient:=oBrw

   activate window oWnd

return nil

James,

I don't work with database objects. I have my own skip blocks.

Database objects are not required. Show me your skipblock.

[Antonio Linares]

Antonio,

Stefan proposed you, in this thread, a solution that does not use the DBF at all.

Its based on the painted row number. Please review it, thanks
