unselect-child

The "unselect-child" signal is emitted when a child is deselected. It carries the deselected child as an argument.

This signal is basically a wrapper for the "deselect" signal emitted by the GtkListItem that has just been deselected. If you mix the two, the same item will emit the same signal twice in response to deselection.

Callback function

void callback(GtkList list, GtkWidget child);
