Hi,
While coding on Glade for my GSoC project, I'd like to select a specific
row in a tree view (backed by a hierarchical GtkTreeStore) while
building it up. For this I am doing something like the following in a loop:
gtk_tree_store_append (model, &iter, ...);
gtk_tree_model_set (model, &iter, ....);
if (is row to select)
gtk_tree_select_iter (selection, &iter);
However, this doesn't work. Removing the "if" conditional and printing
out gtk_tree_selection_get_selected (selection, NULL, NULL) right after
select_iter reveals that only the root element can be selected this way
(printout is 1), while all others don't get selected (printout 0).
Digging a bit deeper, it seems that _gtk_tree_view_find_node(), called
from gtk_tree_selection_select_path(), cannot find an RBNode belonging
to the tree iter's path (it returns TRUE, which makes the next statement
silently return). This is very strange, though, considering that I added
that exact row which the iter points to two statements earlier.
How can this be? I am really stuck with this and need your help! Thanks
in advance.
(Oh, and the tree view is not yet added to a parent widget or shown on
the sreen during the model buildup, if that matters; the model is,
however, set as model of the tree view.)
Regards,
Denis Washington
