Dear All,
I have found the answer to my problem.
I have a sub-menu in which I have a couple of entries. I can check one of
those, which disables the other one. In effect, I can use a check box or
radio buttons to depict the change. I tried to check a menu item in the
signal handler, but that caused a race condition, and the program crashed.
Now, I have used a signal handler of the parent to do this job. Bu parent I
mean, the item which forks the sub-menu. It is working just fine.
Thanks
Kartikay
