the\ console's\ interpreter\ and\ change\ the\ font.\ i.e.\n\ console\ eval\ \{.console\ configure\ -font\ \{Courier\ 14\}\}\n\n----\n'''Examples\ illustrating\ the\ console\ interpreter\ vs.\ the\

(so\ I\ could\ have\ my\ own\ version\ with\ a\ bigger\ font)\ and\ wasted\ some\ time\ wondering\ why\ my\ changes\ weren't\ being\ read.\n\ \ \ 3.\ Maybe\ more\;\ I\ haven't\ looked\ in\ detail.\n\n\[Brian\ Theado\]\ -\ I'm\ pretty\ sure\ my\ console.tcl\ code\ is\ verbatim\ from\ \[console\ for\ UNIX\]--I've\ made\ no\ changes\ to\ it.\ \ I\ don't\ think\ anyone\ would\ object\ to\ enhancing\ the\ comments\ in\ the\ code\ on\ that\ page.\n\nAs\ mentioned\ in\ private\ email,\ I\ recommend\ against\ having\ your\ own\ copy\ of\ the\ library\ console.tcl\ and\ instead\ use\ the\ \[\[console\ eval\]\ command\ to\ get\ access\ to\ the\ console's\ interpreter\ and\ change\ the\ font.\ i.e.\n\ console\ eval\ \{.console\ configure\ -font\ \{Courier\ 14\}\}\n\n----\n'''Examples\ illustrating\ the\ console\ interpreter\ vs.\ the\ main\ Tcl\ interpreter'''\n\nShow\ the\ windows\ available\ to\ the\ main\ application\ interpreter:\n\ winfo\ children\ .\nShow\ the\ windows\ that\ makeup\ the\ console\ toplevel:\n\ console\ eval\ \{winfo\ children\ .\}\n\nText\ typed\ into\ the\ console\ is\ read\ by\ the\ console\ interpreter\ and\ the\ command\ is\ passed\ to\ the\ main\ application\ interpreter.\ \ The\ \[\[console\ eval\]\ command\ provides\ access\ to\ the\ console's\ interpreter.\n\nThe\ console\ uses\ a\ separate\ interpreter\ likely\ in\ order\ to\ avoid\ confusion/collision\ of\ window\ names\ and\ command\ names\ that\ are\ used\ by\ the\ console.\ \ By\ having\ this\ interpreter,\ these\ windows\ and\ commands\ are\ hidden\ unless\ the\ \[\[console\ eval\]\ command\ is\ used.\n\n----\n08/31/2005\ \[BHE\]\ I\ added\ an\ extra\ menu\ to\ the\ menubar\ for\ 'Options'\ and\ created\ an\ (un)word\ wrap\ option.\ \ It\ required\ that\ I\ also\ add\ a\ horizontal\ scrollbar\ and\ change\ the\ geometry\ manager\ from\ 'pack'\ to\ 'grid'.\n\nAdd\ this\ block\ to\ proc\ tk::ConsoleInit\ before\ the\ help\ menu\ is\ added:\n\n\ \ \ \ \ \ \ .menubar\ add\ cascade\ -label\ Options\ -menu\ .menubar.options\ -underline\ 0\n\ \ \ \ \ \ \ menu\ .menubar.options\ -tearoff\ 0\n\ \ \ \ \ \ \ .menubar.options\ add\ checkbutton\ -label\ \"Word\ Wrap\"\ \\\n\ \ \ \ \ \ \ \ \ \ -underline\ 0\ -command\ tk::ConsoleWrap\ -variable\ ::tk::console::wrapLines\ \\\n\ \ \ \ \ \ \ \ \ \ -onvalue\ char\ -offvalue\ none\n\ \ \ \ \ \ \ variable\ ::tk::console::wrapLines\ char\n\nAnd\ then\ add\ the\ horizontal\ scrollbar\ to\ proc\ tk::ConsoleInit\ and\ change\ the\ geometry\ manager:\n\n\ \ \ \ set\ con\ \[text\ .console\ \ -yscrollcommand\ \[list\ .sb\ set\]\ -xscrollcommand\ \[list\ .hsb\ set\]\ -setgrid\ true\]\n\ \ \ \ scrollbar\ .sb\ -command\ \[list\ \$con\ yview\]\n\ \ \ \ scrollbar\ .hsb\ -orient\ horizontal\ -command\ \[list\ \$con\ xview\]\n\ \ \ \ #pack\ .sb\ -side\ right\ -fill\ both\n\ \ \ \ #pack\ \$con\ -fill\ both\ -expand\ 1\ -side\ left\n\ \ \ \ grid\ \$con\ .sb\ -sticky\ nsew\n\ \ \ \ grid\ .hsb\ -column\ 0\ -row\ 1\ -sticky\ ew\n\ \ \ \ grid\ remove\ .hsb\n\ \ \ \ \n\ \ \ \ grid\ columnconfigure\ .\ 0\ -weight\ 1\n\ \ \ \ grid\ rowconfigure\ .\ 0\ -weight\ 1\n\nand\ finally,\ add\ this\ procedure:\n\n\ #\ ::tk::ConsoleWrap\ --\n\ #\n\ #\ Toggles\ the\ word\ wrapping\ in\ the\ console\n\ #\n\ #\ Arguments:\n\ #\ None.\n\ \n\ proc\ tk::ConsoleWrap\ \{\}\ \{\n\ \ \ \ \ variable\

\ \ \ \ \ \ \ grid\ remove\ .hsb\n\ \ \ \ \ \ \ \ \ \n\ \ \ \ \ \}\ else\ \{\n\ \ \ \ \ \ \ \ \ grid\ .hsb\n\ \ \ \ \ \}\n\ \}\n\nIt\ might\ be\ a\ good\ idea\ to\ add\ a\ font\ dialog\ option\ to\ the\ Options\ menu\ as\ well.\n\n\[LV\]\ One\ of\ the\ frustrating\ things\ when\ using\ GUI\ applications\ is\ finding\ that\ they\ haven't\ made\ it\ easy\ to\ change\ the\ font\ size.\ \ Some\ authors\ just\ point\ people\ to\ resource\ files\ or\ suggest\ they\ hack\ the\ code.\ \ But\ adding\ something\ like\ a\ font\ dialog\ option\ would\ be\ a\ great\ step\ forward.\
