I use GtkTreeView to show some data in columns, the data has type G_TYPE_DOUBLE. The problem is that is see the numbers with the full precision. That means .000000 after the floating point. So, how can I specify the exact precision that i need?

You must use a cell data function, which is called every time a row is created. You can control the precision with this. Basically, use gtk_tree_view_column_set_cell_data_func() to add a cell data function to a tree view column. Then, you can customize the displayed text in that function.
