PV Add font


PV Add font ( area ; name ) -> Function result

Parameter	Type	Description
area	Longint	4D View area
name	String	Font name
Function result	Longint	Font ID

Description

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.

Example

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_TEXT($FontName) //Name of font to add/remove from Area

 

 ARRAY LONGINT($FontNumArray;0) //Font numbers array

 ARRAY TEXT($FontNameArray;0) //Font names array

 C_LONGINT($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
