Possible to define a FONT with a saved String ?

[ukoenig]

Hello from Germany,

I have a small problem :

Yesterday i added the option to the messagebar-programm,
that the user can define his own fonts.
The fontstring "NAME Arial SIZE 21 0 BOLD ITALIC"
is saved in a INI-File

Normaly i must do :
DEFINE FONT oFont NAME "Arial" SIZE 21, 0 BOLD ITALIC

The Action creates the Fontstring :

ACTION ( oSAY4:GetFont(), oSAY4:SelFont(), ;
e_FTYP4 := " NAME " + '"' + oSAY4:oFont:cFaceName + '"'+ ;
" SIZE " + ALLTRIM(STR( oSAY4:oFont:nHeight ) ) + ;
", 0 " + ;
IIF( oSAY4:oFont:lBold = .T., " BOLD", "") + ;
IIF( oSAY4:oFont:lItalic = .T., " ITALIC", "" ) )

e_FTYPE4 := is the FONT-STRING will be stored in the INI-File

But it is impossible to work with a Var like
DEFINE FONT oFont e_FTYPE4



Is there another way to handle this, to define a Font with a Var ?

Honestly, I always find so hard to understand your messages. Anyway, have a look at the following sample. I don't know if it will be of any help for you, though:

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oWnd

    LOCAL cVar := "This is a test"

    LOCAL aFont := SELECTFONT( oWnd )

    LOCAL aSaved

    IF EMPTY( aFont ); RETURN NIL; ENDIF

    DEFINE WINDOW oWnd

    @ 1, 1 SAY "This is a test";
           COLOR CLR_BLACK

    @ 3, 1 GET cVar;
           SIZE 100, 20

    @ 5, 1 BUTTON "Choose font";
           SIZE 100, 20;
           ACTION aFont := SELECTFONT( oWnd )

    @ 7, 1 BUTTON "Save font";
           SIZE 100, 20;
           ACTION aSaved := aFont

    @ 9, 1 BUTTON "Restore font";
           SIZE 100, 20;
           ACTION RESTOREFONT( oWnd, aSaved )

    ACTIVATE WINDOW oWnd

    RETURN NIL


STATIC FUNCTION SELECTFONT( oWnd )

    LOCAL aFont := CHOOSEFONT()

    LOCAL oFont := BUILDFONT( aFont )

    IF oFont = NIL; RETURN NIL; ENDIF

    IF oWnd != NIL; REFRESHWND( oWnd, oFont ); ENDIF

    RETURN aFont


#define FW_NORMAL 400


STATIC FUNCTION RESTOREFONT( oWnd, aFont )

    LOCAL oFont := BUILDFONT( aFont )

    IF oFont = NIL; RETURN NIL; ENDIF

    REFRESHWND( oWnd, oFont )

    RETURN NIL


STATIC FUNCTION BUILDFONT( aFont )

    IF EMPTY( aFont[ LF_FACENAME ] )
        RETURN NIL
    ENDIF

    RETURN TFont():New( aFont[ LF_FACENAME ],;
                        ,;
                        aFont[ LF_HEIGHT ],;
                        .f.,;
                        !( aFont[ LF_WEIGHT ] == FW_NORMAL ),;
                        aFont[ LF_ESCAPEMENT ],;
                        aFont[ LF_ORIENTATION ],;
                        aFont[ LF_WEIGHT ],;
                        aFont[ LF_ITALIC ],;
                        aFont[ LF_UNDERLINE ],;
                        aFont[ LF_STRIKEOUT ],;
                        aFont[ LF_CHARSET ],;
                        aFont[ LF_OUTPRECISION ],;
                        aFont[ LF_CLIPPRECISION ],;
                        aFont[ LF_QUALITY ],;
                        ,;
                        aFont[ LF_PITCHANDFAMILY ] )


STATIC FUNCTION REFRESHWND( oWnd, oFont )

    LOCAL i

    oWnd:SetFont( oFont )

    FOR i = 1 TO LEN( oWnd:aControls )
        oWnd:aControls[ i ]:SetFont( oFont )
        oWnd:aControls[ i ]:Refresh()
    NEXT

    RETURN NIL

Thank you very much,

I know, sometimes it is not easy for me, to explain in english
what i mean, but i do my best.

I see, i cannot use the full string
i have to save the parts in a array and use it like :

For

Face := aFont1[1]
Height := aFont1[2]
Bold := aFont1[3]
italic := aFont1[4]

with TFont:New

I have still to test, how a Array works with Ini-Files.

Uwe

Enrico, Thank very much
it's working now
The code, how customers can change the text-type
