WARNING
Although this program is freely distributable (see COPYRIGHT below), I
would appreciate if you take the time to write me a line or two (E-Mail
please) if you are using any of my programs or if you have any kind of
ideas or suggestions (This is not too much to ask, is it?). If you feel
particularly generous, I would like to receive a disk with any useful
programs you have written, preferrably with source. Thanks!
DESCRIPTION
BellPrefs is an interactive, Intuition based preferences module that can
be used to configure Bell. It uses the WB 2.0 user interface style, and
works just like the preferences modules already in your SYS:Prefs drawer.
It allows a digitized sound to be selected through a file requester, and
played with any combinations of volume and pitch values. The sound
waveform is displayed graphically, and the program works under WB 2.0 only.
OPTIONS
usage: BellPrefs (no options)
The program is completely interactive, and does not support command line
parameters (yet?). It can also be run from Workbench, and an appropriate
icon is provided so that it can be placed in your SYS:Prefs drawer. When
run, it opens a window with a couple of gadgets and menu items that will be
described:
GADGETS:
Visual Bell: determines if the bell should be visible, i.e., if the
screen should flash when an error occurs.
Audible Bell: determines if the bell should be audible, i.e., if the
sound should be played when an error occurs.
Volume: determines the volume at which the sound is to be played,
ranging from 0 to 64 (loudest).
Speed: determines the speed at which the sound is to played, ranging
from 4000 to 16000 (fastest). The faster a sound is played, the higher the
pitch will be.
Sound File: this string gadget contains the full pathname of the IFF
8SVX sound file. If you type a pathname and hit return, the sound will be
loaded and the volume and speed gadgets will be changed to reflect the
default values stored in the file.
Select: this gadget brings up a file requester to select interactively
the sound file pathname.
(Graphic): this gadget, when hit, will simulate what will happen in an
error condition according to the current settings. This may produce a
screen flash (if the Visual Bell is enabled) or a sound (if the Audible
Bell is enabled) or both (or even none).
Save: saves the current preferences on disk (ENVARC:).
Use: saves the current preferences in memory (ENV:), and signals Bell
that the preferences have been changed.
Cancel: self-explanatory.
MENUS:
Project/Open...: loads a bell preferences file, selected from a file
requester.
Project/Save As...: saves a bell preferences file, in a file selected
from a file requester.
Project/Quit: quits.
Edit/Reset To Defaults: resets all options to the internal defaults.
Edit/Last Saved: resets all options to the ones saved in ENVARC:.
Edit/Restore: resets all options to the ones saved in ENV:.
BUGS
Should support some command line parameters, just like the system
preferences modules.
