Re: nevermind 2nd part of my last question

[Tristan Van Berkom <vantr touchtunes com>]

I know that with a "GtkFixed" you can remove members and I just looked
at the
code for "GtkTable" and you should be able to remove with:

gtk_container_remove(GTK_CONTAINER(your_table), GTK_WIDGET(your_child));

I know this should do something (well I know that GtkTable provides a
method
for this).

I hope this helps,
Cheers
