With that in mind, my first question is whether this needs to be a new widget, or a new trait.
(Make no mistake: traits may look strange, or they may appear to be hard stuff because of terms like multiple inheritance, but they're usually surprisingly easy to implement.)
I have zero experience with traits, so tell me whether you can add a trait to existing widgets (in this case, Core and Gadget) without subclassing them. But note that LiteClue does *not* subclass Core nor Gadget; it is a subclass of Shell, the hooks are explicitly installed by an API. What OM2.2 did was intended to control the tooltips via resources.
Yes, my traits remark is based on the assumption of either adding to
XmGadget+XmPrimitive+XmManager,
Over my dead package body :-) Remember our discussions on ABI compatibility?
or subclassing them.
I understand that this doesn't solve your problem.
The nice thing about LiteClue is that it does not require you to go over your code, changing every XmPushButton to XmNewImprovedPushButton. Big time saver.
Another issue is that the filtering of events away from X-insensitive widgets is buried rather deep in Xm and Xt. LiteClue works by having its own events dispatcher. So, with Lesstif or OM 2.1 or 2.2, where there is *no* way to make any change inside them, I'm afraid the implementation will never look very clean. It *exists* and I thought that rather than keep it for myself it would be better to put it in an opensource distribution.
Could we please *first* add it to Xlt? Later we could see how to make it a trait, but IMHO that should first be a spec proposal for OM2.3
Still no reply from Rick. He should have been faster if he wanted to object, so send me your stuff and I'll add it to Xlt.

The author has sent me a tarball of his CVS files themselves. Can you inject *that* in the Xlt cvs? So that history doesnt get lost?
Then I will make the patches to add the 'original' (latest) LiteClue to Xlt, which will become the reference site for LiteClue (with changes to the author's site and the Motif FAQ).
Then I will make the changes needed to support an XltLiteClue subclass (with gadget support).
OK?
