* 32.asm TLgetfont and TLnewfont version 0.01 8.6.99
include 'Front.i' ;*** change to 'Tandem.i' to step thru TL's ***
; This program introduces the selection of fonts. There are 5 subrountines
; for this. they use a table of fonts which is pointed to by xxp_FSuite.
; There can be 10 fonts, numbered 0-9, and each of these can have 4 forms,
; theoretically, 40 fonts in all. The window(s) can each have a font &
; font style attached. Or, they can have Topaz/8 attached, i.e. font 0,
; as they do initially.
; Font 0 is always Topaz/8. So, you can use fonts 1-9. If you use TLgetfont
; or TLaslfont on any font already opened, it will be closed, and any
; windows using it will revert to font 0, i.e. Topaz/8.
; Here are the subroutines:
;
; TLGetfont: puts a predetermined fontname and height in an FSuite entry,
; and closes anything already there. Does not open the font.
; TLAslfont: as TLGetfont, but puts up a requester for the font.
; TLNewfont: attaches an xxp_FSuite font & style to the xxp_ window.
; TLFsub: closes an Fsuite font (called automatically by TLWclose)
; The commonest font styles are:
; 0 plain
; 1 bold
; 2 italic
; 3 bold+italic
