RE: Selecting item with another béhaviour

[martyn 2 russell bt com]

 

Sorry for the break in the thread, but I didn't write this mail on my linuxbox.
What I want to do with my GtkListStore is not configure it to be able to select more than one item. I've already post or read a mail about that. What I want to do is to modify the behaviour to select another item in my GtkListStore. 

 

So by this you mean, you want to select ONLY 1 at a time?  If so, just set the selection to SINGLE. 
    selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(treeview));
    gtk_tree_selection_set_mode(GTK_TREE_SELECTION(selection),
    GTK_SELECTION_SINGLE);  

 
So, I must connect my own function on my GtkTreeView. And this function contain the following algorithm :
 
on_click(item) {
 if (is_selected(item) == TRUE)
  {
    set_selected(item, FALSE);
  }
 else
  {
    set_selected(item, TRUE);
  }
}

The problem is that I don't know the name of the event, and I don't know how to change the state of an item (selected or not selected).
  

For the selection change, you want to look at the "changed" event for the selection.

    /* set changed event function */
    g_signal_connect(G_OBJECT(GTK_TREE_SELECTION(selection)), "changed",
       G_CALLBACK(on_treeview_ops_selection_changed),
       NULL);

The function in G_CALLBACK() should look something like this:

    void on_treeview_ops_selection_changed(GtkTreeSelection *treeselection, gpointer user_data)

    {

        ...

    }
