Bad solution.

Not really. Moving a mouse across a widget would generate only a handful
of events. But if you put a single clipping widget over ALL headers and
track mouse motion only in this widget - there would be even less. In fact,
no noticable performace degrade whatsoever (unless one would intentionally
move pointer very fast across the labels back and forth - but even then
user would not notice anything - as no visual feedback is expected).

Ever tried scrolling (or repopulating, resizing, etc.) the matrix with 80 rows
(and about 15 of them visible) on 486 ? :) Even on PII-300 the difference
in performance is noticable between XbaeMatrix and XmAxyList.
Plus, the code is big and there is no way to turn off many features one does
not need (when compiling it statically into the application).
Thanks,
Alex Y.
