Change columns color at run-time TXBrowse()? *Fixed Now*

Postby dutch » Mon Apr 28, 2008 7:46 pm

Dear All,

I try to set color CLR_RED for columns that content 'X' but it's not working.
How can I do that? This is image of my sample code.

Image
Code: Select all  Expand view  RUN
#include 'fivewin.ch'
#include 'xbrowse.ch'

FUNCTION Main

local oWnd, oBrw
local aStatus := { {'1','','X','','X'}, ;
         {'2','X','X','','X'}, ;
         {'3','','','X','X'} }
local n

   DEFINE WINDOW oWnd TITLE "Change columns colors"

   oBrw := TXBrowse():New( oWnd )

   oBrw:nMarqueeStyle       := MARQSTYLE_HIGHLCELL
   oBrw:nColDividerStyle    := LINESTYLE_BLACK
   oBrw:nRowDividerStyle    := LINESTYLE_BLACK
   oBrw:nFreeze             := 1
   oBrw:bLDblClick       := {|nRow,nCol,nKeyFlag| msginfo( eval(oBrw:acols[oBrw:nAt()]:bStrData) ) }

   oBrw:SetArray( aStatus )

   for n := 1 to len(aStatus)
       oBrw:aCols[n]:bClrStd := {|| { CLR_BLACK, iif(eval(oBrw:aCols[n]:bStrData)='X',CLR_RED,CLR_WHITE) } }
   next

   oBrw:CreateFromCode()

   oWnd:oClient := oBrw

   ACTIVATE WINDOW oWnd ON INIT oBrw:SetFocus()

return nil


Regards,
Dutch

Dutch,

Try this:

oBrw:aCols[n]:bClrStd := {|| iif(eval(oBrw:aCols[n]:bStrData)='X',{CLR_BLACK,CLR_RED},{CLR_BLACK,CLR_WHITE } }

Dear James,

It still doesn't work. It likes the eval(oBrw:aCols[n]:bStrData) don't return correctly.

I try this code but still doesn't work.
Code: Select all  Expand view  RUN
oBrw:aCols[n]:bClrStd := {|| iif(aStatus[oBrw:nArrayAt][n]='X',{CLR_BLACK,CLR_RED},{CLR_BLACK,CLR_WHITE }) }

Xbrowse behaves a bit strange on evaluating colors, try it this way

oBrw:aCols[I]:bClrStd := {|| {CLR_BLACK,iif(eval(oBrw:aCols[n]:bStrData)='X',CLR_RED,CLR_WHITE ) } }

Dutch,

>I try to set color CLR_RED for columns that content 'X' but it's not working

I think you have problem with this logic. Do you want to change the color of the entire colomn if there is a X in any row in the column? If so this is going to be very hard to do. You will need to scan the entire database looking for X's before you decide which color to make the column.

You can't do this with a codeblock that is only looking at the current row.

Perhaps I don't understand what you are trying to do?

Dear James,

In the past I use TWBrowse() to do as picture and now I would like to change to TXBrowse().
Image

This is TWbrowse() code that I use. It is able to change bBkColor, bTextColor at runtime.

Code: Select all  Expand view  RUN
   
   REDEFINE LISTBOX oBrw FIELDS  "" ;
       ID 103 ;
                          OF oDlg

   oBrw:nAt       := 1
   oBrw:bLine     := { || aRmNo[oBrw:nAt] }
   oBrw:bGoTop     := { || oBrw:nAt := 1 }
   oBrw:bGoBottom := { || oBrw:nAt := Eval( oBrw:bLogicLen ) }
   oBrw:bSkip     := { | nWant, nOld | nOld := oBrw:nAt, oBrw:nAt += nWant,;
                   oBrw:nAt := Max( 1, Min( oBrw:nAt, Eval( oBrw:bLogicLen ) ) ),;
                   oBrw:nAt - nOld }

   oBrw:bLogicLen:= { || Len( aRmNo ) }
   oBrw:SetArray( aRmNo )

   oBrw:lDrawSelect  := .T.
   oBrw:aColSizes    := aSizes
   oBrw:aHeaders     := aHead
   oBrw:aJustify     := aJust
   oBrw:aHJustify    := aHJust
   oBrw:lAdjBrowse   := .F.
   oBrw:lAdjLastCol  := .F.
   oBrw:lCellStyle   := .T.
   oBrw:nLineStyle   := 11
   oBrw:nFreeze      := 1
   oBrw:nLineHeight  := 20
   oBrw:nHeaderHeight:= 22
   oBrw:lMChange     := .F.
   oBrw:bGoLeft      := {|| oBrw:nColAct > 2 }
   oBrw:bBkColor     := {|nRow,nCol,nStyle| if(nStyle=0,SetClr(oBrw:nAt,nCol,nStyle,oBrw,aRmSt),) }
   oBrw:bTextColor   := {|nRow,nCol,nStyle| if(nStyle=1,SetClr(oBrw:nAt,nCol,nStyle,oBrw,aRmSt),) }
*  oBrw:bFont        := {|nRow,nCol,nStyle| if(nStyle=1.and.aDate[nCol]=1, oFnt:hFont , if(nStyle=0.or.nStyle=3, oFont:hFont , ) ) }
   oBrw:bChange      := {|| oBrw:Refresh() }

   oBrw:nClrNFFore   := oBrw:nClrText
   oBrw:nClrNFBack   := oBrw:nClrPane

Dear Richard,

Your example is the same first sample above and It doesn't work correctly.

Please modify the code like this
Code: Select all  Expand view  RUN
   for n := 1 to len(aStatus)
       oBrw:aCols[n]:bClrStd := { || CellColor( oBrw, n ) }
   next

...
...

//-----------------------------//
static function CellColor( oBrw, n )
return {|| { CLR_BLACK, iif(eval(oBrw:aCols[n]:bStrData)='X',CLR_RED,CLR_WHITE) } }
//-----------------------------//


The problem is because of using loop variable to construct a codeblock.

This is a piece of code from my application, it works OK

Code: Select all  Expand view  RUN
FOR I = 1 TO LEN(oBrw:aCols)
   oBrw:aCols[I]:nWidth    := ASIZE[I]
   oBrw:aCols[I]:oDataFont := {||IIF(DET->SDETAIL,TABCOL[12],IIF(DET->ENR = "3" .OR. DET->ENR = "1"  ,TABOBJ[04], TABCOL[11] ) )  }
   oBrw:aCols[I]:bClrStd := {|| {CLR_BLUE, If( DET->SDETAIL,CLR_YELLOW,CLR_WHITE)  } }
NEXT
