hello,
We have some problems with dynamic MOTIF widget creation and destruction, it
seems that this action makes
memory consumption
environment :
-------------
Digital UNIX V3.2C (Rev. 148); Mon Aug 12 10:39:49 MET DST 1996
Digital UNIX V3.2C Worksystem Software (Rev. 148)
We write a little bench to show the problem
I send you the program : tow files : test_mopo.uil and test_mopo.c
make by :
cc test_mopo.c -threads -D_SHARED_LIBRARIES -Dalpha -D_REENTRANT -lX11 -lXt
-lXm -lMrm -o test_mopo
/usr/bin/X11/uil -w -o test_mopo.uid test_mopo.uil

test_mopo

We run this bench for one night, and on the morning it is impossible to stop
this bench (by ctrl c), we
must reboot the computer !!!

| I've run your code example (thanks) and reproduced the problem.
Creating and destroying widgets repeatedly in this way always leads to
memory "leaks". This is considered a feature of X and not a bug.
We strongly recommend that you re-use widgets instead of destroying then
re-creating them. You should unmanage them, redefine their properties,
and re-manage them.
