public virtual signal void remove (Widget widget)
widget from this.
widget must be inside this. Note that this will own a
widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget.
If you want to use
widget again, you need to add a reference to it before removing it from a container, using
@ref. If you don’t want to use
widget again it’s usually more
efficient to simply destroy it directly using destroy since this will remove it
from the container and help break any circular reference count cycles.
