Hello, Yes, I realised the "error of my ways" at about 3AM this morning. Woke up and thought "Damn, why did I do that for?"
After checking the GTK doc I realised that what I should have done is this: - DONT destroy anything. - Dont ceate a new treeview. - Create the liststore as usual. - use: gtk_tree_view_set_model (GTK_TREE_VIEW(lookup_widget(widget, "treeview4")), GTK_TREE_MODEL(list_store)); According to the documentation, this will automatically destroy and remove any previous model and hook the new model into the Treeview.(I wont have to worry about memory freeing, but I *miht* have to free the list_store. I shouldnt need to worry if the list_store is a local variable though, should I?) I wont have to recreate the entire treeview, just the model/list_store. AND it still keeps with the hide/show modelling that the GTK tutorials and PHP/Mysql examples all referred to (from the SAMS publishing website). Thanks for your comments. They helped me rethink the issues I was having and got me to this stage!
