It is all about treeview. How does tree view maps its record with its attached data model?. I have my own data model where i manipulate the records.
When i add a new record into datamodel, i need to inform to others [treeview] by gtk_tree_model_row_inserted( mode, path, iter), which emits row-inserted signal. i need to fill the position of the record into the path which i pass to this API, by gtk_tree_path_append_index (path, position)
Ie.,
gtk_tree_path_append_index (path, position);
gtk_tree_model_row_inserted (model, path, &iter)
* this API emits row-inserted signal.
* gets iter from given path by calling _get_iter function of our own.
1. Now, does this position value matters to treeview except getting the appropriate record [ to be displayed columns] from data model to display?
2. in the row-activated signal handler of treeview, i get only GtkTreePath which has indices and depth. Assume user clicked on 3rd record, hence gtk_tree_path_get_indices (path)[0] has the value '2'. If i want to get the iter for the same, do i have to depend on this value to retrieve the exact row from the data model?
3. datamodel -> treeview.
Assume i have 10 records initially which is listed in the treeview.
when i append new record [11th] in the datamodel, how can i make that
record to appear on the second row of treemodel.
