problem with clist and option menu

[Jerome Bolliet <bolliet in2p3 fr>]

Hi,

I have found a bug in clist.
I am using a clist widget to display a circular list of message.
When a new message need to be display at the end of the list, and,if the
size of the list is to big, i'm removing the first message. After i'm
forcing clist to display the last message.

But I have found, that if you remove a row at the start of the clist,
and immediatly, you add a row at the end, it seems that there is a
problem with adjustment. The gtk_clist_moveto don't show the row as
expected.

I've made a sample program to show the problem.

I've modify adjust_adjustments in gtk_clist to solve my problem

     if (clist->clist_window_height - clist->voffset != LIST_HEIGHT (clist))
by

     if (clist->clist_window_height - clist->voffset > LIST_HEIGHT (clist))

But i'm not sure that is the good solution.

For the option menu widget, i've a problem with
gtk_widget_set_sensitive.

If i'm making the widget unsensitive, and i change the history of the
widget, when i'm making widget sensitive, some item in menu don't get
their sensitive state.

I've made a sample too.

Bye
