change the ndatalines (xbrowse) on line - RESOLVED -
Posted: Fri May 12, 2023 01:13 PM

Initially a test line in the browse consists of a single example line

WITH OBJECT oBrw
IF lmore
:nDataLines := 2
ELSE
:nDataLines := 1
ENDIF

...
END

Code (fw): Select all Collapse

  :bStrData := { || oDbf:Street + CRLF +oDbf:city+" "+ oDbf:state }

the user by a menu popup can change the configuration and set more rows
on command of menu I made

Code (fw): Select all Collapse

Function oBtnMenu2(oBrw,oDbf,oParent,cSection,nRow,nCol)
   local oMenu,oItem1
  MENU oMenu POPUP
 MENUITEM oItem1 PROMPT "More Rows" ;
      ACTION (lMore := !lMore,;
                 ( IIF( lMore,oBrw:nDataLines := 2,oBrw:nDataLines := 1 ),;
                   oBrw:refresh()) )
      ENDMENU
      oItem1:SetCheck(lMore)
     ACTIVATE POPUP oMenu OF oParent AT  oBrw:nTop+nRow, oBrw:nLeft+nCol
return nil

Why not refresh the oBrw ?

Silvio,

Please try : chr(13)+chr(10) in stead of CRLF

  COLUMNS "ID", "FIRST+CHR(13)+CHR(10)+LAST", ;

     "STREET+CHR(13)+CHR(10)+CITY+CHR(13)+CHR(10)+STATE+ '-' + ZIP" ;

  HEADERS "ID", "NAME", "ADDRESS" ;

I can be wrong ))))

nDataLines is used by xbrowse only while creating the browse for the first time for calculating the row height. After creation of the browse. i.e., during runtime, it is never used and changing the values does not do anything.

During runtime, you can change the data oBrw:nRowHeight.

Not correct.
chr(13)+chr(10) or CRLF should not be inside the quotes.

Code (fw): Select all Collapse

      COLUMNS "ID", "FIRST+CHR(13)+CHR(10)+LAST", ;

is not correct

Code (fw): Select all Collapse

      COLUMNS "ID", "FIRST"+CHR(13)+CHR(10)+"LAST", ;

is correct.
You can use CRLF also.
