How to get a switch's status?

Accessing members of the ext structure is generally not a wise/portable practice, because the values are meant for internal use by LittlevGL and may not be what you expect. (Also, we’re free to change the ext structure in minor releases, so members may be removed/renamed/added.) When they exist, it’s better to use the proper getter functions that are documented for each object type.
