I find the documentation for Athena text widgets rather obscure, so
I'm hoping that some of you who have dealt with this before can answer
my questions ...
My setup: My widget msg_text is of asciiDiskWidgetClass, so a file
holds the messages to it. XtNeditType is set to XttextAppend and
XtNtextOptions are set to
scrollOnOverflow|scrollVertical|wordBreak|editable (<- I'm not sure if
it does any good to put 'editable' here since I'm in textAppend
mode??).
Using the text widget, I type a message to my application window that says,
"Enter a barcode: ". I would then like the user to type in a barcode
which my program can then do marvelous things with! This is the only
time the user has to type anything. The rest of the time I use the
text widget for displaying my messages to the user. I know my code
works ok when I'm displaying messages. I'm just not sure about
getting the response from the user.
1. Am I correct to use textAppend and asciiDiskWidgetClass?
2. How do I capture the user's input to a variable?
3. If using asciiDiskWidgetClass is correct, what would be the best
way of clearing the file every once in awhile, since this program
may be running for days at a time? Should I just close it and
then reopen it?
I will thank you in advance since our mailer is having problems. We
can receive mail, but it's hard to send out right now.
