[Lesstif-discuss] The other XmList problem (bug #916711)

[Danny Backx]

Martin,

I've tweaked your example a bit and attached the outcome to this
message.

With a one line change to List.c, the result of running the test
program is :

dell: {40} list2
Selection (count 1) : 2 
Selection (count 1) : 2 

Is this what we want ? (This is copying Motif's bug ...)

Note that the change to List.c is as yet incomplete : the widget
highlighting doesn't reflect the selection as printed by the
program.
