void MythUICheckBox::CreateCopy ( MythUIType parent)

void MythUICheckBox::Finalize ( void  )
protectedvirtual

Perform any post-xml parsing initialisation tasks.

This is called after the widget has been created and it's state established by ParseElement() or CopyFrom(). A derived class should use this to perform any initialisation tasks which should occur after this point.
