1.1 porting

grp@Unify.com (Greg Pasquariello) (03/26/91)

I am in need of information regarding porting of applications
from Motif 1.0 to Motif 1.1.  I'm kind of naive about Motif (but
I know OLIT really well :-)), so if anyone can help me I would
appreciate it.  I am interested especially in the following:

0.  The answer to this is probably "no", but I'll ask anyway.  Is
    there any chance of compiling a 1.0 appl with the 1.1 toolkit
    and having it work?

1.  What is involved with changes to the functions relating
    to input focus?  We currently use the 1.0 undocumented
    _XmGrabTheFocus(), and need to know how the operation
    of this function (or its analog) has changed with the 
    new toolkit.

2.  What issues are involved with window grabs?  Are they handled
    by the toolkit or the window manager?  If grabs are done differently,
    will it affect my code at all?

3.  Can a 1.1 application function correctly with a 1.0 window
    manager (and vice versa)?  _Is_ there a 1.1 window manager, 
    or is 1.1 just a toolkit release?

4.  If there is a 1.1 window manager, is any programmatic access
    provided to it?

5.  Any major changes to resources?  What they are called, where
    they are found?

6.  Is Motif 1.1 based on X11R3 or X11R4?  If it's based on R4
    can I run my application on an R3 server?

Thanks for any help you may provide.  I _really_ appreciate
it.

Actually the answer is Yes.  But it depends on what you've done of course.
In fact I've even run 1.0 apps with the 1.1 shared libraries - although I
wouldn't ever want to ship something in that configuration.

Use XmProcessTraversal and cross your fingers.

1.1 has a new Mwm.  I haven't used it yet since I expect most of our
customers to still have the old one.  So the answer is Yes.

No more than 1.0, as far as I know.  Although I gather that at 1.0 it didn't
all work correctly.

Some changes wrt who frees XmStrings.

R4, yes.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
