Richedit how to highlight a defined word in memofields ?

[ukoenig]

Hello,

I want to highlight a defined word inside a memofield
from a selected record in xbrowse.
Maybe a solution using < At > and < Textout >

@ 10,20 XBROWSE oBrw SIZE 580, -75 PIXEL OF oDlg ;
COLUMNS "TOPICNO", "FORUM", "LIKE", "T_DELETE", "DATE", "AUTHOR", "INFO" ;
COLSIZES 50, 60, 45, 45, 70, 120, 110 ;
HEADERS "No.", "Forum", "Like", "Del.", "Date", "Author", "Filter or Info" ;
AUTOSORT LINES NOBORDER FONT oMono ;
ALIAS cFileName UPDATE

WITH OBJECT oBrw
:nMarqueeStyle := MARQSTYLE_HIGHLROWRC
:bChange := { || cTCode := (cFileName)->CODE, oTCode:Refresh(), ; include the highlight function
cLink := ALLTRIM((cFileName)->LINK), oLink:Refresh(), ;
cTopic := ALLTRIM((cFileName)->TOPIC), oTopic:Refresh(), ;
nGoRecord := (cFileName)->(RECNO()) }

@ 40, 610 GET oTCode VAR cTCode SIZE 590, 420 PIXEL OF oDlg ; // w h
MEMO READONLY HSCROLL FONT oMono UPDATE



any idea ?

Try using a richtext edit control instead of a multiline edit.

Enrico,

do You have any sample for it to do this on a xbrowse-recordchange ?

Uwe

[Enrico Maria Giordano]

No, sorry.

Uwe,

Please review FWH/source/function/memoedit.prg and look there for function RichEdit()

[Marc Venken]

Antonio,

I don't see any code there that can be used ?

There is a line that calls a .DLL Are funtions insite there ?

[Marc Venken]

Uwe,

We may be looking into the sample

testrtf = code with 1 word highlighted

testrtf5 and find a way there, using richedit as function to browse (show) the data.

Unless someone has done this :: Otto has !

In this topic :

viewtopic.php?f=3&t=34703&hilit=xml

There is a sample in replacing text in XML. Maybe also a possibility

Code: Select all  Expand view

METHOD Colorize( nStart, nEnd, nColor ) CLASS TRichEdit

   ::SetSel( nStart, nEnd )
   RESetCharFormat( ::hWnd, ::oFont:cFaceName, ;
                    Size2Font( ::oFont:nHeight ) * 20, nColor, ;
                    ::oFont:nCharSet, ;
                    ::oFont:nPitchFamily, ;
                    ::oFont:nWeight, ;
                    ::oFont:lItalic, ;
                    ::oFont:lUnderline, ;
                    ::oFont:lStrikeOut )
   ::HideSel()

return nil

It is not my cup of thea, but maybe also with this function something can be done ?

cFind = "Xbrowse"
cText = ((XLM code color)) + "Xbrowse" + ((XLM code endcolor))

and the function below will do it ?

Code: Select all  Expand view

METHOD ReplaceAll( lUndo, cFind, lDown, lCase, lWord, lAll, cText, lMsg ) CLASS TRichEdit5
   
   local   lSw   := .T.
   local   nV    := 0
   local   nPos  := ::GetPos()
   
   DEFAULT lUndo := .T.
   DEFAULT lMsg  := .T.

   Do While lSw
      lSw := ::Find( cFind, lDown, lCase, lWord )
      if lSw
         nV++
         ::ReplaceSel( lUndo, cText )
      endif
   Enddo
   if !Empty( nV )
      if lMsg
         MsgInfo( "End Replace: " + StrZero( nV, 5 ) + " found" )
      endif
   else
      MsgInfo("String not found: " + cFind )
   endif
   ::SetPos( nPos )

return if( !Empty( nV ), .T., .F. )

It is possible that this may help

Is the 5 version a upgrade ?

this code works, but in simple code. Not fancy.

Works with sample dir.

Code: Select all  Expand view

#include "FiveWin.ch"
#include "RichEdit.ch"

function Main()

  local cTitle:="Test"
  local cResult, oMemo
  Public cShowstr:=""
  Public oDlg

  REQUEST DBFCDX

   USE clients via "DBFCDX" NEW

   DEFINE FONT oFont NAME "Courier New" SIZE 8,15
   DEFINE FONT oBold NAME "Courier New" BOLD SIZE 8,15

   DEFINE DIALOG oDlg FROM 5,10 TO 50, 200 font oFont TITLE "Test Color"

   @ 10, 10 XBROWSE oBrw OF oDlg ;
      SIZE 400, 200 PIXEL ;
      COLUMNS 'Name', 'Adress', 'Notes' ;
      ALIAS 'CLIENTS' NOBORDER

   WITH OBJECT oBrw

      :nColDividerStyle := LINESTYLE_LIGHTGRAY
      :nRowDividerStyle := LINESTYLE_LIGHTGRAY
      :bClrRowFocus     := { || { CLR_BLACK, RGB(185,220,255) } }
      :nMarqueeStyle    := MARQSTYLE_HIGHLROWMS

      :bChange := { || oSay:refresh(),showmemo() }

      :CreateFromCode()
   END

   @ 10,460 SAY oSay PROMPT clients->notes SIZE 200,200 PIXEL OF oDlg COLOR CLR_BLACK update  //TRANSPARENT

   ACTIVATE DIALOG oDlg CENTERED

   close all
Return nil

function showmemo()
   Local cStr:=""
   local cChange:= "FiveWin"   //  Word that we will look for
   local cInto:= "\cf2 FiveWin \cf1"  // Put Word in Color


   cText = alltrim(clients->notes)

   cStr  += "{\rtf1\ansi\deff0"
   cStr  += "{\colortbl;\red0\green0\blue0;\red255\green0\blue0;}"
   cstr  = cStr + cText
   cStr  += "}"

   cShowStr = StrTran( cStr, cChange, cInto )  // --> "Harbour Power"

   hDLL = LoadLibrary( 'riched20.dll' )
   @ 250,900 RICHEDIT oMemo VAR cShowstr of oDlg PIXEL SIZE 300,400

return NIL
 

[cnavarro]

Please try with new control

Code: Select all  Expand view

#include "RichEdit5.ch"


    // hDLL = LoadLibrary( 'riched20.dll' )              // Not use this
   @ 250,900 RICHEDIT5 oMemo VAR cShowstr of oDlg PIXEL SIZE 300,400

Christobal,

I got the defined hightlighted words from MEMO displayed.
There are some problems :

1. different typings "xBrowse" found "XBROWSE" not found
2. The MEMO is displayed in just one line NO working linefeed with defined HSCROLL
-- without HSCROLL no formatted text.
3. NO edit possible ( textchange is needed ) .
4. what happens with multiple findings ( a scan must be included ) ?

Is there still something that must be included ?

Code: Select all  Expand view

FUNCTION SHOWMEMO(cText, oFont, cFSeek1, cFSeek2)
LOCAL cStr      := ""
LOCAL cChange   := "xbrowse"                //  Word that we will look for
LOCAL cInto     := "\highlight1 xbrowse \highlight0"  // Put Word in Color
LOCAL cVar      := ""

cStr    += "{\rtf1\ansi\ansicpg1252\deff0\nouicompat\deflang3082{\fonttbl{\f0\fnil\fcharset0 Tahoma;}}"
cStr    += "{\colortbl ;\red255\green0\blue0;\red0\green0\blue0;\red128\green64\blue64;\red0\green0\blue128;}"
cStr    += "\viewkind4\uc1"
cStr    += "\pard\fs20" + if( Empty( cText ), " ", cText )
cStr    += "}"
cStr    := STRTRAN( cStr, cChange, cInto )

IF HB_ISNIL( oMemo )
    @ 70, 625 RICHEDIT5 oMemo VAR cVar OF oDlg SIZE 600, 380 ; // w h
    FONT oFont  PIXEL HSCROLL      
ENDIF
oMemo:LoadRTF( cStr, .F. )
oMemo:GoToLine( 1 )

RETURN NIL

Uwe, test it, and tell me

Code: Select all  Expand view

   IF HB_ISNIL( oMemo )
       @ 5, 5 RICHEDIT5 oMemo VAR cVar OF oDlg SIZE 350, 300 ;
       FONT oFont  PIXEL //HSCROLL
      oMemo:lHighlight := .t.
   ENDIF
   oMemo:LoadRTF( cStr, .F. )
   oMemo:SetPos( 0 )
