MetaTableColumn.setAttribute

void setAttribute(string attribute, gobject.value.Value value = null, glib.types.DestroyNotify destroy = null)

Set the value associated to a named attribute.

Attributes can have any name, but Libgda proposes some default names, see <link linkend="libgda-40-Attributes-manager.synopsis">this section</link>. If there is already an attribute named attribute set, then its value is replaced with the new value, except if value is null, in which case the attribute is removed.

Warning: attribute is not copied, if it needs to be freed when not used anymore, then destroy should point to the functions which will free it (typically [glib.global.gfree]). If attribute does not need to be freed, then destroy can be null.

Parameters

`attribute`	attribute name as a static string
`value`	a #GValue, or null
`destroy`	function called when attribute has to be freed, or null
