19 * @short_description: Widget which plays an interactive fiction game
20 * @stability: Unstable
22 * The #ChimaraIF widget, given an interactive fiction game file to run, selects
23 * an appropriate interpreter plugin and runs it. Interpreter options are set by
24 * setting properties on the widget.
26 * Using it in a GTK program is similar to using #ChimaraGlk (which see).
27 * Threads must be initialized before using #ChimaraIF and the call to
28 * gtk_main() must be bracketed between gdk_threads_enter() and
29 * gdk_threads_leave(). Use chimara_if_run_game() to start playing an
30 * interactive fiction game.

359 * <member>E — East</member>
360 * <member>G — aGain</member>

371 * <member>Z — wait (ZZZZ...)</member>
373 * Some early Infocom games might not recognize these abbreviations. Setting
374 * this property to %TRUE will cause the interpreter to expand the
375 * abbreviations to the full words before passing the commands on to the
376 * game. Frotz only expands G, X, and Z; Nitfol expands all of the above
377 * plus the following nonstandard ones:
379 * <member>C — Close</member>
380 * <member>K — attacK</member>

422 * ChimaraIF:interpreter-number:
424 * Infocom gave each port of their interpreter a different number. The Frotz

440 * ChimaraIF:random-seed:
442 * If the #ChimaraIF:random-seed-set property is %TRUE, then the interpreter
