@get
Description:
Gets the value of one or more cells in the row referenced by iter.
The variable argument list should contain integer column numbers, each column number followed by a place to store the value being retrieved.
The list is terminated by a -1. For example, to get a value from column 0 with type g_type_string, you would
write: `gtk_tree_model_get (model, iter, 0, &place_string_here, -1)`, where `place_string_here` is a gchararray to be filled
with the string.
Returned values with type g_type_object have to be unreferenced, values with type g_type_string or g_type_boxed have to be freed. Other values are passed by value.
Parameters:
| this | |
| iter |
a row in this |
| ... |
pairs of column number and value return locations, terminated by -1 |
