Need help with GtkTreeView

[Petrolea]

Hi everyone!

I'm making a cinema program, which is showing movies names and the dates when they're playing.

When I select a certain row in GtkTreeView everything works fine, I can get the value out of it, but what I want to do is to select a child row and then get the value of its parent too (when I select a date I also want to select movie name).

How could I do this? Any ideas?

This is the code for getting the value out of row that is selected:


void row_act(GtkTreeView *treeview, GtkTreePath *treepath, GtkTreeViewColumn *column, void* data)
{
GtkTreeSelection *selection;
GtkTreeModel *model;
GtkTreeIter iter;
gchar *value;

selection = gtk_tree_view_get_selection(treeview);
gtk_tree_selection_get_selected(selection, &model, &iter);
gtk_tree_model_get(model, &iter, 0, &value, -1);
g_print("Value: %s\n", value);
g_free(value);
}


Thanks in advance!
