public void set_node_attribute (string attribute, Value? value, DestroyNotify destroy)
Set the value associated to a named attribute.
The attribute string is used AS IT IS by this method (eg. no copy of it is made), and the memory it uses will be freed
using the destroy function when no longer needed (if destroy is null, then the string will not be
freed at all).
Attributes can have any name, but Libgda proposes some default names, see this section.
For example one would use it as:
gda_tree_node_set_node_attribute (node, g_strdup (my_attribute), my_value, g_free); gda_tree_node_set_node_attribute (node,
GDA_ATTRIBUTE_NAME, my_value, NULL);
If there is already an attribute named attribute set, then its value is replaced with the new value (value is
copied), except if value is null, in which case the attribute is removed.
