FontID()

Syntax

FontID = FontID(#Font)

Returns the unique system identifier of the #Font.

This result is sometimes also refered to as a 'Handle'. Take a look at the extra chapter Handles and Numbers for more information.

It is also possible to use the result of FontID() to choose from several loaded fonts.
An example of using FontID() in combination with SetGadgetFont():

  If OpenWindow(0, 0, 0, 222, 130, "FontID()", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    ButtonGadget(0, 10, 10, 200, 30, "Click to change the font...")
    Font1 = LoadFont(#PB_Any, "Arial"  ,  8, #PB_Font_Bold)
    Font2 = LoadFont(#PB_Any, "Verdana", 12, #PB_Font_StrikeOut)
    UsedFont = 1
  EndIf

  Repeat
    Event = WaitWindowEvent()

  If Event = #PB_Event_Gadget
    If EventGadget() = 0
      If UsedFont = 1
        SetGadgetFont(0, FontID(Font2))
        UsedFont = 2
      Else
        SetGadgetFont(0, FontID(Font1))
        UsedFont = 1
      EndIf
    EndIf
  EndIf

  Until Event = #PB_Event_CloseWindow
