Command PV Add font

PV Add font

version 6.8

PV Add font (area; name) Longint

Parameter	Type		Description
area	Longint		4D View area
name	String		Font name

Function result Longint Font ID

The PV Add font command adds a font to the area by its name and returns its ID.

If name already exists, the PV Add font command returns its ID (the number can also be obtained using the PV GET FONT LIST command).

For more information on how fonts associated with a 4D View area work, refer to the section PV Style, Introduction.

This method also works with toggle: it removes a font from the 4D View area or associates it if it has already been removed.

   C_STRING(255;$FontName)  `Name of font to add/remove from Area

   ARRAY LONGINT($FontNumArray;0)  `Font numbers array
   ARRAY STRING(255;$FontNameArray;0)  `Font names array
   C_INTEGER($Position)  `Position of the font in the number and name arrays

   $FontName:="Arial"

   PV GET FONT LIST (Area;$FontNumArray;$FontNameArray)  `List of available fonts
   $Position:=Find in array($FontNameArray;$FontName)

   If ($Position=-1)  `$FontName font is unavailable for the area?
      $Position:=Size of array($FontNameArray)+1  `We will add it
      INSERT IN ARRAY($FontNameArray;$Position)  `Resize...
      INSERT IN ARRAY($FontNumArray;$Position)  `...arrays
      $FontNameArray{$Position}:=$FontName  `Assign name of new font
      $FontNumArray{$Position}:=PV Add font (Area;$FontName)  `Assign font number
   
   Else `$FontName font is already present in the area
      PV REMOVE FONT (Area;$FontNumArray{$Position})  `Remove it
   End if

PV GET FONT LIST, PV REMOVE FONT.
