Code: Select all
#include "fivewin.ch"
#include "constant.ch"
Function Test()
Local oDlg,oFont,oBold
Local ObtnSel[10]
Local cFont:=""
Local nSizeFont:=0
Local nBottom := 22
Local nRight := 102
Local nWidth := Max( nRight * DLG_CHARPIX_W, 180 )
Local nHeight := nBottom * DLG_CHARPIX_H
local aGet[20]
local oSay[10]
DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
DEFINE FONT oBold NAME "TAHOMA" SIZE 0,-14 BOLD
DEFINE DIALOG oDlg ;
TITLE "test sel font" ;
SIZE nWidth, nHeight PIXEL FONT oFont ;
STYLE nOr( DS_MODALFRAME, WS_POPUP, WS_CAPTION, 4 ) ;
COLOR CLR_BLACK, nRgb( 245,244,234)
@ 116, 5 SAY oSay[6] Prompt "Carattere" SIZE 80,14 PIXEL OF oDlg TRANSPARENT FONT oBold
@ 126, 5 GET aGet[14] VAR cFont SIZE 200,12 PIXEL OF oDlg
@ 126, 208 GET aGet[15] VAR nSizeFont SIZE 18,12 PIXEL OF oDlg
@ 126, 228 BTNBMP oBtnSel[4] RESOURCE "font.bmp" FLAT SIZE 14, 12 OF oDlg PIXEL ;
COLOR nRgb(238,236,219),nRgb(238,236,219) BORDER;
ACTION (aFont:=ChooseFont(),;
cFont :=aFont[LF_FACENAME],;
nSizeFont:= aFont[LF_HEIGHT ],;
msginfo( nSizeFont),;

If you look into the aFont : there is no correct size from to font ? Strange...
For the save : it seems that the lenght of aGet[15] is to small to see it.

ChooseFont() function of FWH is a straight forward implementation of Windows function ChooseFont().
The font size displayed in the ChooseFont() dialog box is in "Points". This size in points is converted to font height with this formula.
Code: Select all
lfHeight = -MulDiv(PointSize, GetDeviceCaps(hDC, LOGPIXELSY), 72)
To get the size in points, we need to use reverse formula.
Code: Select all
function FontHeightInPoints( nHeight )
local nPoints, hDC
nPoints := Round( Abs( nHeight ) * 72 / GetDeviceCaps( hDC := GetDC( 0 ), 90 ), 0 )
ReleaseDC( 0, hDC )
return nPoints

Thanks Rao
But I not understood How call that function
ACTION (aFont:=ChooseFont(),;
cFont :=aFont[LF_FACENAME],;
nSizeFont:=FontHeightInPoints( aFont[LF_HEIGHT ]),;
aGet[14]:refresh(),aGet[15]:refresh())
run ok
I need also to Know these parameters
Font name
Font size
Color
Bold
Italic
Underlined
Strikethrough
why I not see the color of the font ????

Hello Silvio, please look into EasyReport. Here you see how to do. You have to change the pen before printing.
Best regards,
Otto

Perhaps you not understood what I mean
this Image is from web
here , I not see bold... and color
when you make choosefont you must have
Font name
Font size
Color
Bold
Italic
Underlined
Strikethrough
I remember EasyReport save 20 type of font with 20 type of colors and it no good ( error )
on my app you can select any font you want and then it build a font when it print the text
