# How do I remove the data I have attached to an object?

When attaching the data to the object, you can use the `gtk_object_set_data_full()` function. The three first arguments of the function are the same as in `gtk_object_set_data()`. The fourth one is a pointer to a callback function which is called when the data is destroyed. The data is destroyed when you:

- destroy the object

- replace the data with a new one (with the same key)

- replace the data with NULL (with the same key)
