; to initialize fontObject object (not required):
; ============================================
; fontObject := Object("name","Tahoma","size",14,"color",0xFF0000,"strike",1,"underline",1,"italic",1,"bold",1)

; ==================================================================
; fntName		= name of var to store selected font
; fontObject	= name of var to store fontObject
; hwnd			= parent gui hwnd for modal, leave blank for not modal
; effects		= allow selection of underline / strike out / italic
; ==================================================================
; fontObject output:
;
;	fontObject["str"]	= string to use with AutoHotkey to set GUI values - see examples
;	fontObject["hwnd"]	= handle of the font object to use with SendMessage - see examples
