Re: Deleting selected items from a list

[Jeff Shipman <shippy cs nmt edu>]

I think it's because you are forgetting that selection only
grabs the first one...you have to keep iterating through the
list to get them all. Try something like this:

GList *sel = GTK_CLIST(list)->selection;

while(sel)
{
gtk_clist_remove(GTK_CLIST(list), (int)sel->data);
sel = GTK_CLIST(list)->selection;
}

Hope that helps!
