Re: GtkListStore and Threads problems

[Lorena Salinas <lsalinas invap com ar>]

Hi,

This is what I do inside the worker_thread function
(create_and_start_worker_thread ()) every time I want to update the
model:


gdk_threads_enter();            /* get GTK thread lock */

gtk_list_store_set (GTK_LIST_STORE (host_model), &iter,
                        MYMODEL_COL_STATUS, STATUS_NORMAL,
                -1);

gdk_threads_leave();            /* release GTK thread lock */

I don't know if the problem is because the model is sorted by that
column. I set this using : gtk_tree_view_column_set_sort_column_id
(column, MYMODEL_COL_STATUS) when I create the tree_view for that model
.

Regards,
Lorena
