The helper type to represent any value flowing through the GUI.
Used for converting values from controls to JSON;
Use Tron.proxify
or Tree.proxify
function to make any GUI store its current values as the subjects.
Since in case of Tron.proxify
it is a function (Just
is stored inside), proxify
is safe in that sense, but keep in mind that for Tree.proxify => Tree Control.Value
those values don't change, if one changes the inner control value after that.
