XBrowse – show lines slashed

[Otto]

Is it possible to show some lines in a crossed out font?
Thanks in advance
Otto

Otto,

You have to replace each column row DATA oDataFont

Its not a codeblock so you have to do it manually

[Otto]

Thank you, Antonio. I got it working.

Would you mind sharing the way you did it (the font issue)

Antonio, a codeblock would be a good idea for column data, it could be evaluated easilly

Hello Richard,
here is the define of the font:
StrikeOut is not in font.ch!!!
oFNT := TFont():New( "MS Sans Serif", 10, 15,,.T.,,,,.f.,.f.,.t.,,,,, )
Regards,
Otto

My concern is how did you draw a different font per column without a codeblock being evaluated

Thanks for help

Richard

[Otto]

Do you mean per column or row?
column is standard in xBrowser:

oCol := oxBrw:AddCol()
oCol:cHeader := "...."
oCol:oHeaderFont := oWHSetup:oFntKlein()
oCol:bStrData := { || ...}
---> oCol:oDataFont := oFntAnzeig
oCol:nWidth := 181

Try my snipkeeper.exe.

Hello Antonio,
I did some changes to get rowFont for each column.

Could you please have a look if these changes are save.
xBrowser is very complex and I don't feel secure about my own changes.

In xbrowse-class i made 5 chances:
Please see the red lines

[Antonio Linares]

Otto,

Instead of adding a new DATA, we could check if ::oDataFont contains a codeblock:

Code: Select all  Expand view

METHOD PaintData( nRow, nCol, nHeight, lHighLite, lSelected, nOrder ) CLASS TXBrwColumn

oFont := ::oDataFont

if ValType( oFont ) == "B"
   oFont = Eval( oFont, Self )
endif


Anyhow, there are more places where this must be checked. See next msg

[Antonio Linares]

Code: Select all  Expand view

METHOD DataHeight() CLASS TXBrwColumn
...
   if ::bStrData != nil .and. ::oDataFont != nil
      if ValType( ::oDataFont ) == "B"
         nHeight := FontHeight( ::oBrw, Eval( ::oDataFont, Self ) )
      else   
         nHeight := FontHeight( ::oBrw, ::oDataFont )
      endif   
   endif
...


Code: Select all  Expand view

METHOD DataWidth() CLASS TXBrwColumn
...
   if ::bStrData != nil
       cText := Eval( ::bStrData, Self )
       nLen  := Len( cText )
       if ValType ( ::oDataFont ) == "B"
          oFont = Eval( ::oDataFont, Self )
       else
          oFont = ::oDataFont
       endif     
       while nFrom <= nLen
         cLine  := ExtractLine( cText, @nFrom )
         cLine  := Replicate( "B", Len( cLine ) )
         nWidth := Max( nWidth, ::oBrw:GetWidth( cLine, oFont ) )
       enddo
   endif
...


Code: Select all  Expand view

METHOD CreateButtons() CLASS TXBrwColumn
...
      ::oBtnList:SetFont( If( ValType( ::oDataFont ) == "B", Eval( ::oDataFont, Self ), ::oDataFont ) )
...
      ::oBtnElip:SetFont( If( ValType( ::oDataFont ) == "B", Eval( ::oDataFont, Self ), ::oDataFont ) )

Antonio, do you think 8.01 will have a codeblock for different row height.
For the moment I have hard coded the functionality for my neccessity.

So I can wait for 8.01.

Otto

Each column can have a different font, and the font can change in the same column too. oDataFont is ok for that. Unless I am missing something.

If we have enough time then we will work to include it

[Otto]

Thank you.

I meant not different row height but Font.

Although row height would be nice too depending how much text (memofield) you have.


Could you please post a little example how this font codeblock should look like
and how to evaluate.


At the moment I use this to get the different fonts per column:

oCol:bFntRowData := { || f_fntRowData() }




STATIC FUNCTION f_fntRowData()
LOCAL oFntRow:=""

IF (ordkeyno()) % 2 == 0
oFntRow := oFnt1
elseif
…
ELSE
oFntRow := oFnt2
ENDIF
RETURN (oFntRow)

[nageswaragunupudi]

Mr Antonio

My small suggestion. Instead of having a public data bRowfont or oFont holding either codeblock or font object, if oFont is a setget method( access assign ) we do not have to search where all we need to change in the code.

In my personal copy I have done the same for cFooter so that it works without breaking or making too many changes in the orginal source.

my 2 cents

[Antonio Linares]

Otto,

You use it exactly the same way:

Code: Select all  Expand view

oCol:oDataFont := { || f_fntRowData() }


STATIC FUNCTION f_fntRowData()
LOCAL oFntRow:=""

IF (ordkeyno()) % 2 == 0
oFntRow := oFnt1
elseif
…
ELSE
oFntRow := oFnt2
ENDIF
RETURN (oFntRow)
