TFont for Antonio

[Otto]

Hello Antonio,
Would you be so kind to adapt the functionality of
METHOD SaveToText( nIndent ).

It would be fine having similar functions like
METHOD SaveState( aData )
METHOD RestoreState( cInfo ) in xBrowse
for TFont class.

Thanks in advance
Otto

Otto,
I save the font of mine xbrowses on file Ini

I create a setup for colums,background and fonts Ican call on each table(xbrowse) :




For the fonts then I save on file ini

Sample :
[FntBrowse]
mvBrwFont=Forte:10:Normale;Elephant:10:Normale;Engravers MT:10:Normale;




and then on xbrowse I call the fonts at init for Head,Dataa and Footers


Do you like it ?

Hello Silvio,
this question is about TFont.

But please post you code. I am sure it is useful for many of us.

Best regards,
Otto

Mr Otto

Can you pls try these two functions?

Code: Select all  Expand view  RUN

//----------------------------------------------------------------------------//

function FontToText( oFont )
return FW_ValToExp(  { ;
   oFont:cFaceName, 0, oFont:nInpHeight, .f., oFont:lBold, oFont:nEscapement, ;
   oFont:nOrientation, nil, oFont:lItalic, oFont:lUnderline, oFont:lStrikeOut, ;
   oFont:nCharSet, oFont:nOutPrecision, oFont:nClipPrecision, oFont:nQuality, ;
   nil, oFont:nPitchFamily }  )
//----------------------------------------------------------------------------//

function FontFromText( cText )
return HB_ExecFromArray( TFont(), "NEW", &cText )

//----------------------------------------------------------------------------//

Dear Mr. Rao,
thank you for helping me.

If I read the Font from the restored value the result differ from the original Font. I did many tests this afternoon also with the build in method cGenPrg with the same result.
Please see the screen shot.
The height is not like the original.

Best regards,
Otto











This is my test program

Dear Mr. Rao,
thank you. Your code is working fine.
I had a mistake here.
FontToText( oSay:oFont )
@ 5,40 BUTTON "FontToText";
SIZE 100,50;
ACTION (cVar := FontToText( oFont ),memowrit( "RAOfont.txt",cVar) ) OF oWnd

But I still have a different behaviour with the build in class oFont:cGenPrg().

with build in:
oFont := TFont():New( 'Verdana', 21.12, 48, .f., .f., 0, 0, 400, .f., .f., .f., 0,3, 2, 1,, 34 )
with your code and this gives the correct behaviour if you use FontFromText( cText )
{"Verdana", 0,-48, .F., .F., 0, 0, , .F.,.F.,.F.,0,3,2,1,,34}

Best regards,
Otto

[nageswaragunupudi]

Please modify this line method cGenPrg

Code: Select all  Expand view  RUN

     cCode    += "'" + ::cFaceName + "', " + nTrim( ::nwidth ) + ", " + nTrim( ::nHeight ) + ", .f., "
 

as

Code: Select all  Expand view  RUN

      cCode    += "'" + ::cFaceName + "', " + nTrim( ::nInpwidth ) + ", " + nTrim( ::nInpHeight ) + ", .f., "

Dear Mr. Rao,
this is the output of your file:
{"Calibri", 0, -19, .F., .F., 0, 0, , .F., .F., .F., 0,3, 2, 1, ,34}
This of method cGenPrg:
'Calibri', 0, -19, .f., .f., 0, 0, 400, .f., .f., .f., 0,3, 2, 1, , 34 )
There is a difference in one value.
I think this value is ::nWeight .
Best regards,
Otto

[nageswaragunupudi]

Yes. :nInpWidth and :nWeight
I revised the function too

Code: Select all  Expand view  RUN

//----------------------------------------------------------------------------//
function FontToText( oFont )
return FW_ValToExp(  { ;
   oFont:cFaceName, oFont:nInpWidth, oFont:nInpHeight, .f., oFont:lBold, oFont:nEscapement, ;
   oFont:nOrientation, oFont:nWeight, oFont:lItalic, oFont:lUnderline, oFont:lStrikeOut, ;
   oFont:nCharSet, oFont:nOutPrecision, oFont:nClipPrecision, oFont:nQuality, ;
   nil, oFont:nPitchFamily }  )
//----------------------------------------------------------------------------//
function FontFromText( cText )
return HB_ExecFromArray( TFont(), "NEW", &cText )
//----------------------------------------------------------------------------//
 

Now, these functions and also cGenPrg method of oFont should work reliably
